| A | B |
|---|
| chromosomes | structures contain DNA and become dark when stained |
| cell cycle | interphase and mitosis |
| interphase | G1, S, and G2 |
| G1 | duplication of organelles |
| S | DNA synthesis |
| G2 | functional check for reproduction |
| mitosis | prophase, metaphase, anaphase, and telophase |
| prophase | chromatin coils are visible, nuclear envelope and nucleolus disapppear, spindles form between centrioles; centrioles moved to poles |
| metaphase | chromosomes move to the equator of the cell and attach by the centromeres to the spindles |
| anaphase | chromosomes split appart |
| telophase | nuclear envelope and nucleolus reappear, chromosomes uncoil, last phase of mitosis |
| cell plate | forms when a plant cell divides |
| prophase | longest phase of mitosis |
| interphase | longest period of cell cycle |
| sister chromatids | duplicated chromosomes for two halves |
| centromere | structure where chromatids are held together |
| spindle | football-shaped fibers made of microtubules attached to centrioles |
| spindles fibers | structure where centromeres are attached |
| volume of cell | increases much faster than surface area |
| yolk of ostrich egg | largest known cell |
| limiting factors of cell size | available nutrients, DNA design, and area to volume ratio |
| cancer | uncontrolled dividing cells |
| cells | grow until cells touch each other |
| cancer | grows cells on top of each other |
| cancer killers | lung, colon, breast, and prostate |
| causes of cancer | environmental factors and genetic factors |
| environmental factors of cancer | cigarette smoke, UV rays, air/water pollution |
