Botany - Sexual Reproduction in Flowering Plants Question with Solution | TestHub
Cross-pollinating plants
(i) Produce offsprings having variation among themselves.
(ii) Reduces inbreeding depression.
(iii) Results in the production of pure line homozygous offsprings.
(iv) Having bisexual flowers or have monoecious conditions.
Options:
Answer:
Solution:
Pollination is the process of transfer of pollen grain from anther to stigma of the female reproductive organ. If the transfer is to a different flower of different plant then it is considered to be cross pollination. Cross pollination promotes variation in the plants thus, supporting evolution process. Cross pollination results in formation of heterozygous condition rather than homozygous condition.
If the transfer of pollen grain is in the same flower or neighboring flower of same plant then it is called self pollination. Self pollination helps develop pure line of offsprings and it generally occurs in bisexual flowers.
