In many single-celled organisms, reproduction occurs asexually by producing spores and sexually by producing a) filaments b) thylakoids c) zoospores eliminate d) zygotes

D) zygotes

Explanation:

The zygote is formed in the process of fertilization, in which the male gamete merges with the female gamete in the uterine tube, during sexual reproduction. For this process to occur, it is necessary that the sperm deposited in the woman's vagina enter the cervix and go towards the tubes. Until it reaches the tube, the sperm swims for about 2 to 7 hours.

Fertilization is important because it restores the number of chromosomes in the species. It is also important to emphasize that sex determination occurs with fertilization. If the sperm that fertilized the oocyte is X, we will have a female embryo; if the sperm is Y, we have a male. At the end of the fertilization process, we have the zygote formed.
