Kingdom Plantae

Kingdom Plantae

General characteristics

1. There are many variations of the kingdom and they all possess chlorophyll A and B, thus capable of photosynthesizing i.e. convert sunlight energy into chemical energy and thus are producers of the ecosystem.
2. They have well developed vegetative bodies and are sometimes differentiated into roots, stems and leaves and also reproductive bodies.
3. They are sessile/limited locomotion which show curvature movements.
4. Plants have cellulose cell walls.
5. They have prominent large vacuoles in their cells and store carbohydrate in the form of starch.
6. They are multi-cellular organisms with apical growth and localized growth with indefinite number of parts.
7. Their life cycle involves alteration of generation which is more prominent in the lower plants.

Classification of Kingdom Plantae

1. Bryophyta e.g. musci e.g. funaria
2. Filicinophyta (pteridophyta) e.g. dryopteris filix
3. Coniferophyta e.g. pine (pinus sylvestris).
4. Angiospermophyta. E.g. (flowering plants) class; monocotyledonae, dicotyledonae.
