| DESCRIPTION | The egg cell, or ovum, is the female reproductive cell. Unlike the sperm, the egg cell is large. It contains cytoplasm and unwound DNA, which promotes internal movement and flow. When the sperm and egg meet, they make a zygote that will grow and divide to become a full person. This is a cute gift for health teachers, gynecologists, or expecting parents. |
