Why is a control system for mitosis for animals and plant’s necessary?

to avoid constant cell division when necessary and when not

Explanation:

Control of the cell cycle is needed for various reasons. If the cell cycle were not regulated/controlled, cells could constantly undergo cell division over and over. While this may be beneficial to some cells (which includes cancer cells as this stage of continuous division is a favourable condition for the cells leading to the promotion of cancer (carcinogenesis)), apart from this, reproduction without cause would be biologically wasteful.

Internal regulation of the cell cycle is also important to indicate movement from one phase to the next at proper times. This regulation is not based on thorough time restriction, but rather with feedback from the cell.

Extreme regulation of this process make certain that a dividing cell's DNA is  properly copied, any errors in the DNA are repaired by the repair system after a feedback mechanism, and each daughter cell receives a full set of chromosomes. This is achieved through checkpoints in each phase of the cell cycle. Two groups of proteins, called cyclins and cyclin-dependent kinases (Cdks), are involved in the progress of the cell as it undergoes this cycle through the various checkpoints there are.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
