Question

Choose the correct statements
a. Inability of seed germination due to immature embryo is called Quiescence.
b. Seed coats of Fabaceae do not absorb $O_{2}$ and $H_{2}O$.
c. Germination of tomato seeds is inhibited by chemical compounds.
d. Seeds of polygonum require exposure to low temperature.

• A. a, b, c, d
• B. b, c, d
• C. c, d
• D. a, b, d

Hint:

Germination barriers include seed coat impermeability, immature embryo, chemical inhibitors, and temperature needs.

Answer 1

The Correct Option is A

All statements are correct. Quiescence is due to an immature embryo. The seed coat of Fabaceae acts as a barrier to water and oxygen. Tomato seed germination is inhibited by certain chemicals in the seed coat, and polygonum seeds need chilling (low temperature) to break dormancy.
