What are the classes of kingdom Plantae?
Kingdom Plantae is broadly composed of four evolutionarily related groups: bryophytes (mosses), (seedless vascular plants), gymnosperms (cone bearing seed plants), and angiosperms (flowering seed plants).
What are the five 5 main groups of kingdom Plantae?
Kingdom Plantae includes green, brown and red algae, liverworts, mosses, ferns and seed plants with or without flowers.

Which is the important characteristics for the classification of Kingdom Plantae?
Solution. They are multicellular, eukaryotic organisms. The cell membrane is surrounded by a thick cell wall of cellulose. Except a few aquatic life forms, plants are non-motile.
Which is the important characteristics for the classification of kingdom Plantae?
How does Moss reproduce?
Mosses reproduce by branching and fragmentation, by regeneration from tiny pieces of photosynthetic tissues, and by the production of spores. The spore, under favourable conditions, germinates and grows into a branching green thread, the protonema.
How do organisms in Kingdom Plantae reproduce?
Reproduction in Kingdom Plantae The species in Kingdom Plantae reproduce in a variety of methods. Some species reproduce sexual and others use asexual means. The kingdom also includes a variety of reproductive structures, such as seeds, pollen, sperm, cones, spores, flowers, and eggs.
How do ferns and mosses reproduce?
To reproduce sexually, mosses and ferns produce sperm and eggs. The motile sperm must be able to swim through water to reach and fertilize the eggs, which is why most mosses and ferns live in damp habitats. Even in the absence of rainfall, moisture-laden fog or morning dew produce enough water to accomplish this task.
What are the stages of reproduction in plants?
Sexual reproduction takes place with slight variations in different groups of plants. Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. The haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures.
How many classes are there in the plant kingdom?
D. The Plant World is here regarded as readily divisible into four- teen phyla, thirty-three classes, and many more orders.
Is Plantae asexual reproduction?
Plants can reproduce asexually, without the fertilization of gametes, by either vegetative reproduction or apomixis.
How do angiosperms and gymnosperms reproduce?
Pollen allows angiosperms and gymnosperms to reproduce away from water, unlike mosses and ferns which require water for sperm to swim to the female gametophyte.
