PLANT REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The best way for a plant to reproduce when a pest species is introduced is ____
A
asexual
B
sexual
Explanation: 

Detailed explanation-1: -Sexual reproduction in flowering plants involves the production of separate male and female gametophytes that produce gametes. The anther produces pollen grains which contain male gametophytes. The pollen grains attach to the stigma on top of a carpel, in which the female gametophytes (inside ovules) are located.

Detailed explanation-2: -sexual reproduction, the production of new organisms by the combination of genetic information of two individuals of different sexes. In most species the genetic information is carried on chromosomes in the nucleus of reproductive cells called gametes, which then fuse to form a diploid zygote.

Detailed explanation-3: -In dioecious plants, sexual reproduction requires close proximity to potential mates, but clonal growth can increase this distance and, therefore, reduce the probability of mating. Reduction in sexual propagules can lead to decreased dispersal and gene flow between populations.

Detailed explanation-4: -The most common method for asexual propagation is from cuttings. A cutting is any detached plant part which, under favorable conditions for regeneration of missing parts, will produce a new plant identical to the parent plant.
