Mitosis+Cookie+Model



Interphase: When the female ascaris lays her egg, the cell breaks down nutrients for energy (metabolic activity) and the cell is growing. This leads to the doubling of chromosomes.

Prophase: The chromosome and its twin, chromatid, come together and become thicker. This is when fibers start to evolve, and also the start of cell division. Centrioles then move to opposite sides of the cell. When the nucleus breaks down the chromosomes encapsulate. The spindle fibers begin to extend from the centrioles.

Metaphase: The spindle fibers extend out of the centromeres and connect with the chromosomes.

Anaphase: The spindle fibers pull the separate, identical chromosomes to opposite sides of the cell. While this is happening, each of the daughter cells an identical cell chromosomes.

Telophase: The spindle fibers start to disappear, chromosomes detach and they become more difficult to visualize, and the mass chromosomes develop their own nuclear membrane and make a brand new nucleus. The cell membrane splits and two new cells are formed.

Cytokinesis: In the last phase of mitosis, the cell divides and becomes two daughter cells and they each have the same amount of chromosomes and their own nucleus.

__What is produced during Mitosis?:__ In the end, two daughter cells are produced with the same amount of chromosomes and they each have their own nucleus.

__Why must body cells go through Mitosis?:__ Body cells must go through mitosis to repair the cells when they are damaged, repair the cells, also when they are damaged, and mitosis is also necessary because it allows and organism to grow and develop. an organism started with a parent cell, and ends with two daughter cells. There are more cells in the end, so it helps the species grow and develop.

__Mitosis occurs by in a step-by-step sequence. Predict what would happen if a step was missed or the sequence got out of order. Explain your answer.__ I think if a step was missed or something was out of order, the results would not be the same at the end of the process compared to when nothing was missed or was in the right order. To get the end product (two daughter cells), each step of mitosis needs to happen, and in the right order, otherwise that won't happen, and you could get something totally different. Mitosis is very helpful for an organism, and without the two daughter cells by the end, it will become a problem.
