Here's a breakdown:

* Gametes: These are specialized reproductive cells (sperm and egg) that contain half the number of chromosomes of a normal cell. This ensures that when they fuse during fertilization, the offspring receives the correct number of chromosomes.

* Ova (eggs): These are the female gametes, produced in the ovaries. They are large, non-motile cells that contain all the genetic material needed to create a new organism.

Key features of ova:

* Large size: Ova are much larger than sperm cells, containing nutrients for the developing embryo.

* Non-motile: Ova are stationary and cannot move independently.

* Haploid: They have half the number of chromosomes as a normal cell.

* Contain genetic material: They carry the female's genetic contribution to the offspring.

The process of producing ova is called oogenesis, which occurs in the ovaries throughout a female's reproductive life.
