This video contains multiple choice questions about Bryophytes.
Pteridophytes have following characteristics
1. They are basically land plants that grow well in moist, shady and cool places.
2. The plant body is differentiated into true roots, stem and leaves.
3. They have well-developed specialised tissues for conduction. Xylem transports
water and phloem translocates food.
4. The main plant body is a sporophyte which has true roots, stem and leaves with
vascular tissue.
5. The gametophyte is reduced to a simple small prothallus.
6. The plants exhibit alternation of generation with the sporophyte being dominant.
7. The stem of most ferns except tree ferns is an underground, horizontally growing
rhizome. As it is underground, ferns are the first plants to appear after the forest
fire.
8. The rhizome produces numerous roots called adventitious roots . In
Adiantum whenever a leaf surface touches the soil surface it gives out adventitious
roots and hence is called a walking fern.
9. The size of the leaves in pteridophytes varies considerably.
- in Selaginella-the leaves are very small and are called microphylls.
- in ferns- the leaves are large and are called macrophylls.
