amoeba sisters video recap of mitosis: the amazing cell process that uses division to multiply
1. mitosis is done by your body cells. what types of cells do not undergo mitosis?
2. describe 2 ways that mitosis is important for your body.
3. this illustration is trying to demonstrate something that mitosis is not. in mitosis, the cells that are created are
4. mitosis is just one small part of the cell cycle! describe what would occur if cells were in mitosis more than they were in interphase.
5. when cells are dividing, it is important to understand that they have to move chromosomes equally to both cells. based on this illustration, describe what a chromosome is made of.
6. mitosis starts and ends with diploid cells. that means they have two sets of chromosomes (both parents each contribute a set). in humans, how many chromosomes should be in each of these diploid cells after mitosis?

Question

Accepted Answer

### Question 1:
# Brief Explanations:
Body cells (somatic cells) undergo mitosis, but gametes (sex cells: sperm and egg cells) do not. Gametes are involved in sexual reproduction and are produced via meiosis, not mitosis.
# Answer:
Gametes (sperm cells and egg cells) do not undergo mitosis.

### Question 2:
# Brief Explanations:
1. Mitosis is important for growth: as an organism grows, mitosis produces more cells to increase size (e.g., a child growing into an adult, cells dividing to make the body larger).
2. Mitosis is important for repair: when the body is injured (like a cut or a broken bone), mitosis helps replace damaged cells with new, healthy ones to heal the tissue.
# Answer:
1. Mitosis is important for growth (producing more cells as the organism grows).
2. Mitosis is important for repair (replacing damaged cells to heal injuries).

### Question 3:
# Brief Explanations:
In mitosis, the daughter cells are genetically identical to the parent cell (they are clones). The illustration is likely showing that mitosis does not create genetically diverse cells (unlike meiosis) or that it’s not a process that creates cells with different genetic information. So the cells created in mitosis are genetically identical to the original cell.
# Answer:
In mitosis, the cells that are created are genetically identical to the parent cell (clones).

### Question 4:
# Brief Explanations:
Interphase is when the cell grows, replicates its DNA, and prepares for division. If cells were in mitosis (division) more than interphase (preparation/growth), the cells would not have enough time to grow, replicate DNA properly, or synthesize necessary proteins/organelles. This would lead to cells being too small, with incomplete DNA replication, or lacking essential components, which could cause errors, cell dysfunction, or even cell death. The cell cycle has mitosis as a small part (10%) and interphase as most (90%) for a reason—cells need the time in interphase to be ready for division.
# Answer:
If cells were in mitosis more than interphase, cells would not have enough time to grow, properly replicate DNA, or synthesize necessary components. This would cause defective cells (too small, incomplete DNA, etc.), leading to errors, dysfunction, or cell death.

### Question 5:
# Brief Explanations:
From the illustration (showing chromosomes, DNA, and proteins), a chromosome is made of DNA and proteins. The DNA carries the genetic information, and the proteins (like histones) help package and organize the DNA into the chromosome structure.
# Answer:
A chromosome is made of DNA and proteins.

### Question 6:
# Brief Explanations:
Human diploid cells have 46 chromosomes (2 sets of 23, one from each parent). Mitosis is a process of cell division that results in two daughter cells, each with the same number of chromosomes as the parent cell (to maintain the diploid number). So after mitosis, each diploid cell should have 46 chromosomes.
# Answer:
In humans, each diploid cell after mitosis should have 46 chromosomes.
