Important Questions for NCERT Class 11 Biology Plant Kingdom
Questions. Why are bryophytes called the amphibians of the plant kingdom?
Answer : They are found in damp, moist places as they require water for fertilization.
Questions. In which plant will you look for mycorrhiza and coralloid roots?
Questions. The male and female reproductive organs of several pteridophytes and gymnosperms are comparable to floral structures of angiosperms. Make an attempt to compare the reproductive parts in the table given below:
Answer : a- Flowers b- carpel c- stamen d- seeds
Questions. Give three features that have lead to the dominance of vascular plants?
Answer : 1. Development of deep roots capable of penetrating the soil.
2. Development of water proofing material like cutin on leaves to reduce water loss.
3. Development of strong woody material to anchor and support above ground.
