Which statement is true for all sexually reproducing plants and animals? a) The process of mitosis always produces diploid cells
vazorg [7]

Answer:

d) The process of meiosis produces haploid cells

Explanation:

<em>Meiosis is a form of cell division that involves sex cells. A single diploid sex cell divides twice (meiosis I and meiosis II) to produce four haploid daughter cells. Meiosis is sometimes referred to as reductional cell division because involves halving of the chromosome number of the parent cell.</em>

When meiosis takes place in animals, the haploid cells produced can be directly referred to as gametes. However, in plants, haploid cells give rise to haploid gametophytic generations or simply gametophytes. The gametophytes eventually gives rise to gametes.

Hence, the most correct option is d.
