Question

Germinating seed shows which type of movement? Give an example of chemotropism other than pollen germination.

Answer 1

Explanation:

first part

Epigeal Germination: In this type of germination, the hypocotyl elongates rapidly and arches upwards pulling the cotyledons which move above the soil. ...

Hypogeal Germination: In this type of germination, the epicotyl elongates and the cotyledons remain below the soil.

second part

Nitrogen fixation

Answer 2

Answer:

In this kind of germination, the cotyledons do not come out of the soil surface. In such seeds the epicotyl (i.e., part of embryonic axis between plumule and cotyledons) elongates pushing the plumule out of the soil. All monocotyledons show hypogeal germination
