ICSE Class 9 Biology
Question 4 of 11
Seeds - Structure and Germination — Question 5
Back to all questions(a) Two differences between Coleorhiza and Coleoptile:
| Coleorhiza | Coleoptile |
|---|---|
| Protective sheath of radicle | Protective sheath of plumule |
| Present towards the pointed end of embryonic region | Present towards the upper broader side of the embryonic region |
(b) Two differences between Bean seed and Maize grain:
| Bean seed | Maize grain |
|---|---|
| Two cotyledons | One cotyledon |
| No endosperm | Large endosperm present |
(c) Two differences between Germination and vivipary:
| Germination | Vivipary |
|---|---|
| When the embryo in the seed becomes activated and begins to grow into a new plant, then it is known as germination. | Vivipary is known as the germination of seed within the fruit, while it is still attached to the parent plant. |
| Germination is a common and widespread method of plant reproduction. | Vivipary is less common and is typically observed in plant species adapted to specific environments, such as wetlands or coastal areas. |
