Answer:

Option (C) and (D).

Explanation:

Reproduction may be defined as the process by which the new offspring are produced from the parents. Two main types of reproduction are asexual reproduction and sexual reproduction.

The asexual reproduction involves the process of mitosis. No zygotes is formed during the process of asexual reproduction. The offspring produced from the asexual reproduction are genetically identical or similar to ts parent. The chromosome number of the offspring and parent are same. The daughter leaf cell has 24 chromosomes.

Thus, the correct answer is option (C) and (D).

Let us consider each statement separately. A zygote is the result of the fusion of two gametes (reproductive cells) and thus only appears in sexual reproduction. For the same reason, E) is wrong; meiosis is a step in the making of gametes and again, a plant that reproduces asexually does not produce gametes. B) is also wrong since (healthy) members of the same species have the same number of chromosomes. The leaf cells of the daughter plant will have 24 chromosomes. The only case where this would not hold, is the case of sexual reproduction, where the gametes of the new organism have half the chromosomes of the ancestor organisms. Hence, C and D are correct. We have already justified D. As far as C is concerned, in asexual reproduction we have that every organism passes his whole genome to his offspring and this creates a lot of clones next to each other. Every plant in a garden of a species that reproduces asexually may be genetically identical and some biologists consider them for that reason as the same organism!
