Animal reproduction - Fertilization depends on mechanisms that bring together sperm and eggs of the same species
3 important questions on Animal reproduction - Fertilization depends on mechanisms that bring together sperm and eggs of the same species
Explain what gonads are, and what forms there are.
Gonads are the organs that produce gametes in most animals. The female gonads are the ovaries, the male gonads are the testis
Explain what gametes are and what forms there are.
Gametes are haploid cells that fuse with other haploid cells during fertilization in sexual reproduction. The female gamete is called the ovum (or egg) male gametes are called sperm.
Explain what a spermatheca is and how it works.
A spermatheca is a part of the female reproductive system in many insect species. It is a sac in which sperm may be stored for extended periods, these male gametes are only released in response to appropriate stimuli which ensures fertilization occurs under circumstances that are well suited to embryonic development.
