Reproductive System The system of organs within an organism that work together for the purpose of reproduction.

Meiosis is a special type of cell division necessary for sexual reproduction and the cells that are produce are called gametes. In animals, the gametes.

Multicellular Organisms

Tissue - a group of similar cells that together perform a specific function in an organism.

Organ - a structure in a plant or animal that is made up of different tissues working together to perform a specific function.

meiosis - a part of sexual reproduction in which cells divide to form sperm cells in a male and egg cells in a female. Meiosis occurs only in reproductive cells.

sexual reproduction - a type of reproduction in which male and female reproductive cells combine to form offspring with genetic material from both cells. Flowers are the sexual organs of flowering plants

fertilization - Part of the process of sexual reproduction in which a male reproductive cell and a female reproductive cell combine to make a new cell that can develop into a new organism.
