2 . Define the type of germination taking place
3 . Give any one example of the same
4 . Name them:
a) the young root that grows into the root system of the plant
b) the seed leaves.
Answers
Answer:
a. In hypogeal type of germination, the epicotyl elongates and the cotyledons remain below or on the surface of ground e.g., gram. In epigeal type of germination, the hypocotyl elongates pushing the cotyledons above the ground e.g., bean.
b. In epigeal germination (or epigeous germination), the hypocotyl elongates and forms a hook, pulling rather than pushing the cotyledons and apical meristem through the soil. ... Beans, tamarind and papaya are examples of plants that germinate this way.
c. In most cases, the beginnings of the roots in plants are found in the embryo within the seed. This is called a radicle and will eventually form the primary root of a young plant. The primary root will then evolve into one of the two main types of roots in plants: a taproot system or a fibrous root system.
d. The answer is the Seed Leaf! The seed leaf stores food and provides the developing seedling food for respiration, so the seed can release energy for its own growth. The seedling continues to develop and grow and soon, its true leaves will appear and it will no longer depend on the seed leaf for food.
