Polar body is a small non-functional cell that is produced in meiosis during oogenesis.

Cleavage of zygote results in the formation of daughter cells called blastomeres.

Placenta secretes relaxin along with other hormones.

Acrosome in the head of a spermatozoon contains enzymes that facilitate the penetration of the sperm into the ovum.
