Sea Urchin Egg

The reproductive cell from which a sea urchin develops, often used in developmental biology research.

Holoblastic Cleavage

A cleavage pattern in which the entire embryo cleaves; characteristic of eggs with little or moderate yolk (isolecithal or moderately telolecithal) (e.g., the eggs of echinoderms, amphioxus, and mammals). Compare with meroblastic cleavage.

Meroblastic Cleavage

Cleavage pattern observed in the telolecithal eggs of reptiles and birds, in which cleavage is restricted to a small disc of cytoplasm at the animal pole. Compare with holoblastic cleavage.

Cleavage Pattern

The division of cells in the early embryo, determining the spatial arrangement of cells in the resulting organism.
