Describe classification of kingdom Plantae. Mention one characteristic and one example of each class.

Classification of Kingdom Plantae: Plant kingdom includes eukaryotic organisms usually with embryonic stage. The major plant groups are-

● Thallophyta- Plants that do not have well-differentiated body design fall in this group. The plants in this group are commonly called algae. Example- Spirogyra, Ulothrix.

● Bryophyta- These are called the amphibians of the plant kingdom. The plant body is commonly differentiated to form stem and leaf-like structures. Example- Funaria.

● Pteridophyta- The plant body is differentiated into roots, stem and leaves and has specialised tissue for the conduction of water and other substances from one part of the plant body to another. Example- Marsilea

● Gymnosperms- The plants of this group bear naked seeds and are usually perennial, evergreen and woody. Example- Pinus.

● Angiosperms- In the angiosperms or flowering plants, the pollen grains and ovules are developed in specialised structures called flowers. Example- Maize
