SOMEONE PLEASE ANSWER!! What is the purpose of mitotic cell division in multicellular organisms (give all 3 purposes)? Compare this to the purpose of mitotic cell division in single celled eukaryotes.

Multicellular organisms depend on mitosis for growth and repair.

When an animal, plant or other multicellular organism grows, it makes more cells through mitosis.

Organisms can repair some of their tissues, using mitosis to regenerate new cells.

Explanation:

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
