In this video we are going the learn the topic classification of the Plant Kingdom.
- The plants have been divided into five classes:
- Algae
- Bryophytes
- Pteridophytes
- Gymnosperm
- Angiosperm
- 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
