Division | either Mitosis or Meiosis |
Somatic Diploid Cells (2N | normal everyday body cells which have chromosomes in homologous pairs of two |
- the symbol for diploid cells | 2N |
Cell Divides... | because they continue to grow and grow, and the bigger they are the more nutrients they need=they starve |
Tumors | a buildup of cells as a result of multiple mutations causing cells to divide uncontrollably and not die when they should |
non-cancerous, slow growing, doesn’t damage surrounding tissue, doesn’t spread, usually doesn’t come back, BUT can turn malignant | Benign Tumor |
cancerous, fast growing, damages surrounding tissue, spreads throughout the body, often comes back because it can be hard to treat all mutated cells after spreading | Malignant Tumor |
You can see the chromosomes during Interphase yet even though they’re there. Instead, you simply see the nucleus. | false, you can not |
P in PMAT is | Prophase- Sister Chromatids become visible because
nucleus breaks down |
M in PMAT is | Metaphase
Sister Chromatids meet in the middle |
A in PMAT is | Anaphase
Sister Chromatids are moved apart by Spindle Fibers made by Centrosomes organelles |
T in PMAT is | Telophase
two new nuclei form around each cluster of chromosomes |
Sexuel Reproduction | Meiosis |
Who has 2 rounds of division | Meiosis |
Do meiosis produce two daughter cells | Produces 4 unique Haploid (N) Gamete sex cells with 23 chromosomes |
Does round do copy round 1 | No, interphase does not repeat |
Tetrads | appear because nucleus breaks down |
Crossing Over | occurs pieces of DNA are exchanged among each tetrad forming new unique & diverse chromosomes |
In cytokineses | Cytoplasm pinches in half forming 2 new cells that are completely different from each other and its parent |
Gametes | Haploid sex cells (sperm and egg) |
Haploid Cells (N) | contain half the # of chromosomes as Diploid (2N) cells |
