mitosis
| Term | Definition |
|---|---|
| Sexual reproduction | Offspring are made using two parents and sex cells, so they have mixed traits. |
| Asexual reproduction | Offspring are made from one parent and are genetically identical. |
| Binary fission | One single-celled organism splits into two identical cells. |
| Fission | A parent organism splits into parts, and each part grows into a new organism. |
| Budding | A new organism grows off the parent, then breaks away. |
| Regeneration | An organism can regrow lost parts or form a whole new organism. |
| Vegetative propagation | New plants grow from stems, roots, or leaves instead of seeds. |
| bulb formation | New plants grow from bulbs that store food (like onions). |
| sporulation | An organism produces spores that can grow into new organisms. |
| cutting | A piece of a plant is cut off and grown into a new plant. |
| grafting | Parts of two plants are joined together so they grow as one. |
| Cross-pollination | Pollen moves from one plant to another plant, increasing variation. |
| selective breeding | Humans choose organisms with desired traits to reproduce. |
| Nondisjunction | Chromosomes do not separate correctly during meiosis, causing errors. |
| mitosis | Division of body cells to make identical cells for growth and repair. |
| meiosis | Division that makes sex cells with half the normal chromosomes. |
| interphase | Cell grows, copies DNA, and prepares to divide. |
| prophase | Chromosomes condense and spindle fibers form. |
| metaphase | Chromosomes line up in the center of the cell. |
| anaphase | Chromatids separate and move apart. |
| telophase | Two new nuclei form. |
| Cytokinesis | The cell splits into two cells. |
| chromosome | Structure made of DNA that carries genetic information. |
| chromatin | Uncoiled DNA found in the nucleus. |
| chromatid | One of two identical halves of a chromosome. |
| centromere | Region that holds sister chromatids together. |
| spindle fibers | Fibers that pull chromosomes apart. |
| centriole | Structure that helps organize spindle fibers in animal cells. |
| diploid | Cell with two sets of chromosomes (most body cells). |
| haploid and monoploid | Cell with one set of chromosomes (sex cells). |
| somatic cell | Any non-sex body cell. |
| daughter cell | Cell formed after cell division. |
| cyclosis | Movement of cytoplasm to move materials inside the cell. |
| pinocytosis | Cell takes in liquids through its membrane. |
| protein synthesis | Process where cells make proteins using DNA instructions. |
