- Plant classification is the process of grouping the plants on the basis of their similarities and separation from each other depending on the differences they exhibit.
There are more than 3,90,000 species of various kinds of plants (3,52,000 angiosperms, 1,050 gymnosperms, 15,000 ferns, 22,750 mosses) on the earth. Plants are distributed in all possible habitats including forests, mountains, high altitude regions, deserts, ponds, rivers, streams, and oceans. The study of such a diverse group without a classification is a very difficult task.
The plants are broadly classified into 5 divisions namely Thallophyta, Bryophyta, Pteridophyta, Gymnosperms, and Angiosperms. This classification is based on 4 characteristics viz., organization of plant body in root, stem, and leaves, presence or absence of vascular tissue, presence or absence of flowers, and nature of ovules (specifically, whether ovules are enclosed or naked).
This video describes the process of plant classification with suitable examples and the logic behind it. It also explains the complexity and evolution status of each group.
Thank you for a this lecture. It is crystal clear and very easy to follow, great presentation.
👌🏻👌🏻😇
Great
