| Question | Answer |
|---|---|
| The process of cell division; cells make exact copies of themselves | mitosis |
| Reproduction by simple cell division; requires only one parent | asexual reproduction |
| The form of reproduction in which cells from two parents unite to form a zygote | sexual reproduction |
| A threadlike strand of DNA inside the nucleus | chromosome |
| The process that reduces the number of chromosomes in reproductive cells | meiosis |
| A kind of growth where organisms keep the same body features as they grow larger | direct development |
| A change in the shape or characteristics of an organism's body as it grows | metamorphosis |
| A characteristic that is passed from parent to offspring | inherited trait |

| A weak trait-will only show if the offspring receives one from both parents | recessive trait |
| Structure on chromosomes that contains the DNA codes for a trait an organism inherits | gene |

| Cells going through this process produce identical copies of the original cells | meiosis |
| Egg, Larva, Pupa, Adult | Complete Metamorphosis |
| Egg, Nymph, Adult | Incomplete Metamorphosis |
| The cell makes exact copies of chromosomes | Cell is preparing for mitosis |
