Question

Temperature below the optimum level (i)________ the growth of the embryo. Whereas temperatures much higher than the optimum range (ii)_______ the embryo.

• A. (i) inhibits (ii) destroys
• B. (i) destroys (ii) inhibits
• C. (i) enhances (ii) destroys
• D. (i) enhances (ii) inhibits

Answer 1

The correct option is A

(i) inhibits (ii) destroys

Very low temperature inhibits the growth of the embryo, whereas very high temperature destroys the enzymes and delicate tissues of the embryo. The seeds kept at lower temperatures can resume the growth when optimum temperature is provided. But seeds kept at very high temperatures get destroyed permanently.
