|---|---|
| Another word for body cells | somatic cells |
| Examples of somatic cells | Skin, bone, blood |
| Are somatic cells diploid or haploid ? | Diploid |
| Are somatic cells produced through mitosis or meiosis? | Mitosis |
| Another word for sex cells | Gametes |
| Examples of gametes | egg cells, sperm cells |
| what is gametes produced through? | Meiosis |
| How many sets of chromosomes are in a diploid | 2 sets |
| What kind of chromosomes are in a diploid | Homologous |
| What are diploids referred to as? | "2n" |
| How many chromosomes does a human have? | 46 |
| What are diploids produced by? | Mitosis |
| Are diploids produced in body cells or gametes? | Body |
| How many sets of chromosomes does a haploid have? | One |
| What is haploid referred to as? | "n" |
| What are haploids produced by? | Meiosis |
| Are haploids produced in body cells or gametes? | gametes |
| Mitosis | splitting of nucleus |
| Cytokinesis | Splitting of cytoplasm |
| Stages of mitosis | Prophase, metaphase, anaphase, telophase |
| What happens to chromosomes during prophase? | They become visible |
| What happens to nuclear membrane during prophase? | It disappears |
| Sister chromatids | The identical copies of a chromosome |
| Centromere | The connection between the two chromatids |
| Where do chromosomes line up during metaphase? | In the middle |
| What happens to chromosomes during anaphase? | They separate and move to opposite ends of the cell |
| How many nuclei are formed during telophase? | 2 |
| What happens to chromosomes during telophase? | they become less visible |
| What happens to the nuclear membrane during telophase? | reforms |
| Cell plate | new cell wall is created to separate the daughter cells |
| Cleavage furrow | the pinching of the cell to separate the daughter cells |
| End of mitosis | two new nuclei |
| end of cytokinesis | 2 new cells |
| cell cycle | phrase used to describe life and reproduction of an individual cell |
| 3 major phases of cell cycle | interphase, mitosis, cytokinesis |
| interphase | Normal state of the cell, where it grows and carries out cell functions |
| Gap 1 phas | cell grows |
| synthesis phase | DNA is replicated |
| gap 2 phase | cell grows, prepares for mitosis |
| homologous chromosomes | 2 pieces of DNA within a diploid organism which carries the same genes |
| centromere | region of a chromosome to which the microtubules of the spindle attach during cell division |
