Question

Select FALSE statement from the following.

• A. A persistent nucellus is called a perisperm.
• B. The integuments of an ovule harden as tough protective seed coats.
• C. The micropyle remains as a small pore in the seed coat and facilitates entry of oxygen and water into seed during germination.
• D. The general metabolic activity of the embryo is high post-fertilization.

Answer 1

Answer: (D)

Nucellus tissue around the embryo in ovule is referred to as perisperm. After fertilization the integuments form the seed coat -testa and tegmen. The pollen tube entry opening micropyle persists in seed to facilitate entry if oxygen and water.
After fertilization, the metabolic activity in embryo development is not high.
