The process of sexual reproduction can be defined as the formation of a new individual by matting two gametes.In humans and the majority of other eukaryotes — plants as well as animals — the two gametes are differ in structure ("anisogamy") and are contributed by different parents. To meet and unite food to nourish the developing embryo gametes need motility. In animals (and some plants), these two rather contrasting needs are met by anisogametes: sperm that are motile (and small) and eggs that contain food.
What is Reproduction? How important the chapter Reproduction is? What is the difference between male and female reproductive organs? What is gametogenesis? To get these answers, study the video and go through the text given below. Gametogenesis is a process in which an organism makes gametes, cells which are used in sexual reproduction.
