These are small groups of seed plants which are represented by only 900 living species. Eukaryotes are more complex and much larger than prokaryotes. Try refreshing the page, or contact customer support. The sex organs in bryophytes are multicellular, the male sex organs in bryophytes is called antheridium (which produces biflagellate antherozoids) and the flask-shaped female sex organ is called archegonium (produces a single egg). (c) parental body is distributed among the offspring ), some specific chemicals (usually secondary metabolites) and the chemical nature of proteins have been utilised to establish similarities and relationships. Answer: Which of the following options correctly identifies artificial and natural methods of vegetative propagation? These in turn, divide by mitosis to form a haploid plant body once again. (a) bulbs Answer: Plant Nutrients in Soil They belong to the kingdom Monera and are classified as bacteria because they resemble bacteria when observed under a microscope.

(a) slow metabolism Plus, get practice tests, quizzes, and personalized coaching to help you The five kingdoms classification involves Kingdom Monera, Protista, Fungi, Plantae, and Animalia. Habitat Archaebacteria are known to be the oldest living organisms on earth. The system was initiated by Engler and PrantI (1887-1899) in Die Naturalichen Pflanzefamilien. In homothallic fungi, the opposing sexual functions are performed by separate cells belonging to the same mycelium. The male sex organs is called spermatogonium or antheridium. Kingdom Fungi Overview, Characteristics & Examples | What is Fungi? Parasitic fungi that commandeer nutrients from plant hosts utilize specialized hyphal structures that allow them to penetrate host cells. Deposition of calcareous shell around zygote occurs in (d) Tapeworm, earthworm, honeybee Fungi can reproduce by many mechanisms, both sexually and asexually, with the particular mechanisms employed dependant on species. (b) Eyes Lesson : 2 The Kingdom Monera, Protoctista and Fungi (634 KB) 2. Flowers Monera Types & Examples | What is Monera? (2019) published to Nature demonstrated that fungi may have colonized the land much earlier than thought by applying spectroscopic analysis to 1 billion-year-old shale formations in arctic Canada, finding multicellular organic-walled microfossils with a strong resemblance to the branching and terminal bulbous structures of hyphae. Answer: Bryophytes include the various mosses and liverworts. Classification of Algae Class-Phaeophyceae (Brovin Algae) ii. They evolved about 130-160 million years ago. Following fertilisation, zygote develops into an embryo and the ovules into seeds. (c) occurs after fertilisation, Question 54. Bryophytes in general are of little economic importance. This kind of life cycle is called haplontic. Answer: Apart from this, they are completely distinct from prokaryotes. In heterosporous ferns, the female gametophyte depends on food stored by the megaspore. "What are Fungi?". Economic Importance of Gymnosperms The natural system of classification is based on natural affinities among the organisms. The multicellular female gametophyte is also retained within megasporangium. (d) birds (d) both (a) and (b). (d) Onion Saw dust of conifers is used in making plastics and linoleum. Some members of this kingdom seem like they would fit in elsewhere, like sponges or coral. They are used in scrubbing and polishing. To know additional about plants, it is vital to know more about the Some cells of the sporophyte undergo reduction division (meiosis) to produce haploid spores (which germinate to produce gametophyte). Classification of Angiosperms Each fragment gets develop into a thallus. These represent largest algae. (b) 10 (a) single-celled zygote. (b) Crow, 30 years Development of new individual from female gamete without fertilisation is termed as (b) perennial plants Question 55. The plant body of large forms often differentiated into holdfast (with which it usually attaches to the substratum) a stalk called the stipe and lamina (frond), which is photosynthetic. These are xylem and phloem present throughout the body. Question 40. Staminate flowers produce Updated: 07/23/2021 Table of Contents It also has antitumour properties. The smallest angiosperm is water plant Wolffia and tallest is Eucalyptus regnans (100 mand above). Xylem consists of tracheids and phloem is made up of sieve cells and albuminous cells. Kingdom Monera: Characteristics, Classification Read more . The sporangia produce spores by meiosis in spore mother cells. Artificial System of Classification (c) tubers Disadvantages of natural system are given below The polar : nuclei eventually fuses and forms diploid secondary nucleus. Archaebacteria, eubacteria and cyanobacteria are the three domains of kingdom monera. 2nd edition. Algae are chlorophyll-bearing, simple, thalloid, autotrophic and largely aquatic (both freshwater and marine) organisms. The members of Chlorophyceae are commonly called green algae. Equilibrium Constants and its Significance Read more . Algae are divided into various classes based on pigmentation, stored food and flagellation. Kingdom Plantae Carolus Linnaeus is known as father of Taxonomy. Bryophytes commonly grow in -moist, shaded areas in hills. Animals can be endotherms (sometimes termed warm-blooded) like you or ectotherms (cold-blooded) like a frog. (ii) Ferns protect soil from erosion by providing a good cover on the hill slopes and other fragile places. (a) Bamboo, Question 23. (i) This is not helpful in plant identification.

(c) morphology and physiology of the organism (d) Formation of pollen grains Image Courtesy:1. (b) Gametes are always formed. (d) parthenogenesis. Archaebacteria: Introns are present in archaebacteria. All seed bearing plants, gymnosperms and angiosperms follow this pattern of life cycle. Once an animal is grouped into a kingdom, it is further grouped into phyla (singular is phylum), and there are 35 phyla within the Animalia Kingdom. Julie has taught high school Zoology, Biology, Physical Science and Chem Tech. However, surface conduction through capillarity is an important mechanism of water supply to aerial parts. Each pollen grain germinates on the stigma forming a pollen tube that carries two male gametes to the embryo sac, growing through the tissues of stigma and style. 3. A fruit is actually a ripened ovary. Learn the Animalia definition, characteristics of kingdom Animalia, and about the organisms in the Animalia kingdom with Animalia examples. The term Pteridophyte was coined by Haeckel (1866). (d) Bulbil Eubacteria: Other than binary fission, budding and fragmentation, eubacteria are capable of producing spores in order to remain dormant during unfavorable conditions.

Get unlimited access to over 84,000 lessons. * Vegetative Reproduction It occurs by fragmentation and by budding in the secondary protonema from exposed rhizoids and other parts (like gemmae, buds and tubers). Five Kingdom Classification . 2. Asexual Reproduction through binary fission. Answer: (b) 12 years, Question 25. (d) all of these, Question 29. Fertilisation Eubacteria. Differences between Bryophytes and Pteridophytes, 2 Gymnosperms, Angiosperms and Plant Life Cycles. Meiosis does not occur in It is a creeping, green, branched and frequently filamentous stage; the second stage is the leafy stage which develops from the secondary protonema as a lateral bud. Sexual Reproduction During this male and female sex organs are produced either on the same or on different thalli. Select the monocarpic plant out of the following. Prokaryotic and Eukaryotic Cells Economic Importance of Angiosperms a. asexual reproduction only Bacteria are in the kingdom Monera. (a) Habitat Most of the red algae are marine with greater concentrations found in the warmer areas. They take part in fixation and absorption of water. The characteristic features of Chlorophyceae are discussed below (c) dioecious The seeds contain food laden tissue called endosperm. (i) Chromosome number is constant for a species, e.g., 46 in man, 48 in apes and potato, 20 in maize, 16 in onion and 8 in Drosophila. thinning paints, varnishes, etc., and resin is used extremophiles); Eubacteria traditional bacteria including most known pathogenic The main criteria for classification used by him include cell structure, thallus organisation, mode of nutrition, reproduction and phylogenetic relationships. The mode of reproduction is sexual or asexual. The largest kelps are Macrocystis (40-100m) and Nereocystis (20-30 m). (b) length of juvenile phase Bacteria (c) Both X and Y Three types of archaebacteria are found: methanogens, halophiles and thermophiles. 18 Apr. (v) About 70 species of marine alga are used as food, e.g., Porphyra, Laminaria and Sargassum. Some animals are fast, like the peregrine falcon (200 mph when diving) and the cheetah (over 60 mph). (b) Size They range from simple branched, filamentous forms (Ectocarpus) to profusely branched forms as represented by kelps. Vegetative propagation is the term used for (iii) Mosses along with lichens are the first organisms to colonise rocks. (c) 20 years Interestingly, this is a case of convergent evolution, where gill structures have developed separately in several lineages. (d) all of these. * The brown algae that are used as food are Laminaria, Nerocystis, Macrocystis, Alaria, etc. The gametophyte may be produced directly or first from a juvenile stage called protonema. The levels of classification might also provide information on the evolutionary history of a species or other taxonomic group. Answer: (d) Sporophyte The sporophyte in mosses is more elaborate than that in liverworts. Which of the following is a post-fertilisation event in flowering plants? (i) This system use only few superficial characters (i.e., habits, numbers, colours and shapes of leaves, etc) which leads to many orgarfisms grouped together, However, most algal genera are haplontic, some of them such as Ectocarpus, Polysiphonia and kelps are haplodiplontic. They include almost all the major kingdoms except kingdom monera. Taxol is an anticancer drug obtained from Taxus. It is essential to know about plants and their functions and characteristics. The phylogenetic system of classification indicates the evolutionary as well as genetic relationships among organisms. (h) Reproduction Vegetative reproduction occurs through fragmentation (e.g., Sargassum), adventitious branches and stolons (e.g, Dictyota). Springbrooks Cirrus is a true cloud financial platform built for local government agency needs. (b) Layering Bulbils.

Cytotaxonomy is based on cytological information like chromosome number, structure, behaviour and type of chromosomes. The female gamete is bigger, passive, non-motile and laden with food, e.g., Volvox, Fucus. Most are unicellular and live in an aquatic environment, swimming with the aid of a single flagellum and frequently acting as parasites to insects, plants, and amphibians. Eubacteria: Eubacteria are cocci, bacilli, vibrio, rods, filaments or spirochetes in shape. The wall of the ovary forms Contact us: inquiries@biologydictionary.net FOLLOW US What if I also told you that these are not some alien creatures in a science fiction movie but, instead, living among us and are all members of the Animalia Kingdom? The gymnosperms (Gymnos = naked; sperma = seeds) are plants in which the ovules are not enclosed by any ovary wall and remain exposed, both before and after fertilisation. Sexual reproduction in Fucus, Volvox, and Albugo is oogamous; The sporophyte in liverworts is more elaborate than that in mosses; Both, Pinus and Marchantia are dioecious Monera Kingdom Monera exclusively includes all forms of bacteria. The studies with electron microscope made it clear that bacteria and related organisms have a different nuclear structure as compared to others. Answer: Kingdom Monera Cell wall is composed of cellulose, pectose and phycocolloids. Question 53. (c) Cell Wall The cell wall contains cellulose, pectic compounds and certain mucopolysaccharides called phycocolloids, such as agar, carrageenin, etc. They remain within the sporangia retained on the sporophytes. (d) all of these. Liverworts (Hepaticopsida) usually grow in moist, shady places such as banks of streams, marshy ground, damp soil, bark of trees and deep in the woods. smooth walled and tuberculate. Answer: (d) Thallus It is heterotrichous filament with both prostrate and upright branches (Ectocarpus). Home Science Biology Difference Between Archaebacteria and Eubacteria. 2017. Other animals are slow, like the giant tortoise (0.2 mph) and the sloth (1 mph). So, what were those mysterious critters? The gametes fuse and produce a diploid zygote, that represents sporophytic generation. Types of Classification System They help in conduction of food materials. Which of the following organisms has the highest number of chromosomes? Also Read: Kingdom Monera, Protista and Fungi. Recommended Video: Uses of Fungi. Archaebacteria:Archaebacteria are three types: methanogens, halophiles and thermophiles. A distinct male gametophyte may not be present. (iii) Sphenopsida (Equisetum) (d) haploid gametes. (a) Offset * Alginic acid is a phycocolloid obtained from a number of brown algae such as Alaria, Macrocystis, Ascophyllum, Laminaria.
