Question

give reasons for following statements
(a) nature favours cross pollination (b) vegetative propagation is quicker than sexual reproduction
(c) some plants produce large flowers with sweet smell​

PLEASE ANSWER

Answer 1

1. In self-pollination, there will be fusion of male and female gametes from the same parent plant. ... However, in cross-pollination, the fusion of two different male and female gametes results in variation in the progeny produced. Hence, nature favours cross-pollination over self-pollination.

2. the reason is asexual reproduction there is only one parent. ... only one parent is needed. it is more time and energy efficient as you don't need a mate. it is faster than sexual reproduction.

3. Sweet scents attract daytime pollinators such as bees, butterflies and flies. When the flower is ready for pollination, their scent is the strongest; it diminishes as the flower's need for pollination declines.

hope this is helpful for you....
