The egg cell is typically not capable of active movement, and it is much larger (visible to the naked eye) than the motile sperm cells.
The corona radiata is directly adjacent to the zona pellucida, the outer protective layer of the ovum.
embryo
Guard Cells surround the stomata, and enable it to open or shut.
The function of the chicken ovary is to produce and release eggs. Each ovary contains a cluster of developing egg cells called ova, which mature and are released periodically for fertilization.
A group of bacterial cells is called a colony. This term refers to a visible cluster or grouping of individual bacterial cells that have multiplied and accumulated in a particular area.
The cells that cluster around the medullary sinuses in the lymph nodes are called reticular cells. These cells form a network of connective tissue, providing structural support for the lymph nodes. They also play a role in filtering lymph and facilitating immune responses.
This cluster of cells change the baby grows from pre-embryo to embryo to fetus.
embryo
Embryo, between the 3rd and 8th week. Fetus, after the 8th week

The function of the chicken ovary is to produce and release eggs. Each ovary contains a cluster of developing egg cells called ova, which mature and are released periodically for fertilization.
The developing cells before they are considered an embryo are called blastomeres. These are the cells that form during early stages of embryonic development through the process of cleavage.
It is called the cell wall.
The glial cells that surround the cell bodies of peripheral neurons are called satellite cells. Satellite cells provide support and nourishment to the neurons and help regulate their environment.
A bone callus is the lump of immature bone cells that surround a fracture.
A group of bacterial cells is called a colony. This term refers to a visible cluster or grouping of individual bacterial cells that have multiplied and accumulated in a particular area.
