KK: /ˈoʊəˌsfɪr/
A large, immobile female reproductive cell that is produced in the ovaries and is ready to be fertilized.
The oosphere is essential for reproduction in many plants and animals.
Oosphere → It is formed from "oo-" (from Greek "oion", meaning egg) and "sphere" (from Greek "sphaira", meaning ball or globe). The word "oosphere" refers to the egg cell, particularly in the context of plant biology, indicating its spherical shape.
Think of the Greek word for egg ('oo-') and the shape of a ball ('sphere') to remember that an oosphere is an egg cell.
