In this video we are going the learn the topic classification of the Plant Kingdom.
The plants have been divided into five classes:
Algae is aquatic in nature
The example of unicellular algae is Chlamydomonas
The example of colonial form algae is Volvox
The example of filamental form algae is Spirogyra
The plant body of algae is thalloid (a plant body which can not be differentiated into root, stem, and leaf)
Bryophytes include the various mosses and liverworts that are found commonly growing in moist shaded areas in the hills.
Bryophytes are known as the amphibians of the plant kingdom because these plants can live in soil but are dependent on water for sexual reproduction
In bryophytes, Vascular tissue is absent
The plant body of bryophytes is more differentiated than that of algae
Body of bryophytes is thallus-like and prostrate or erect, and attached to the substratum
Pteridophytes are the first teresterial plants
The vascular tissues are very well developed to absorb the water
Sporophytic generation is present in pteridophytes that they reproduce by asexual spores
Gymnosperm includes pinus and cycus, growing in cold conditions
Gymnosperms are said to be flowering plants as they produce flowers having naked seeds
In gymnosperm, ovule is not enclosed in ovary
Flowers of gymnosperm are called cones
Angiosperms are the highly eveolved group of plants
Angiosperms are the flowering plants having seeds which are enclosed within the ovary
Vascular tissues are well developed
Angiosperms are divided into monocot plants and dicot plants
