Flashcards

Exogenous Segregative Cell Division

A type of asexual reproduction where new cells are formed through division that is external to the original cell.

Endogenous Segregative Cell Division

A type of asexual reproduction where new cells are formed through division that occurs inside the original cell.

Siphonous

Having a body composed of a single, continuous cell without cross walls.
