• B. Development of plants without the fusion of gametes.
• C. Inability to perceive stimulus for flowering.
• D. Effect of low temperature on plant growth.

Answer 1

Answer: (B)

Development of plants without the fusion of gametes.

Apomixis is a mode of asexual reproduction. The development of plants takes place without fusion of gametes. It is a powerful tool which fixes heterosis. The developed seeds are maternal clones. The somatic cell directly forms aposporous initial cells which form embryo and finally develops into the seed. In some cases, the megaspore mother cell directly forms the embryo sac and develops into the seed.

So, the correct answer is option B.
