Vocabulary
- Reproduction — The process of making new organisms.
- Asexual Reproduction — A type of reproduction involving only one parent, resulting in offspring that are genetically identical to that parent.
- Binary Fission — A specific type of asexual reproduction where a single cell grows, copies its genes, and divides into two identical cells (e.g., bacteria).
- Sexual Reproduction — A type of reproduction involving two parents, resulting in offspring that have a combination of genes from both parents and are genetically distinct from either parent.
