No, not all organisms reproduce using cell division. While cell division is a fundamental process for growth and repair in all living organisms, it's not the sole method of reproduction.

Here's a breakdown:

Organisms that reproduce using cell division (asexual reproduction):

* Single-celled organisms (prokaryotes and many protists): They reproduce by binary fission, where one cell divides into two identical daughter cells.

* Some multicellular organisms: Some plants, fungi, and animals can reproduce asexually. Examples include budding in yeast, vegetative propagation in plants, and fragmentation in some animals.

Organisms that reproduce using gametes (sexual reproduction):

* Most multicellular organisms: They reproduce sexually, involving the fusion of specialized sex cells called gametes (sperm and egg) to form a zygote, which develops into a new organism.

Key takeaway: Cell division is essential for growth and repair in all organisms, but it's only one of the ways organisms can reproduce.
