Detailed explanation-1: -To maintain homeostasis, every cell must constantly monitor its energy level and appropriately adjust energy, in the form of ATP, production rates based on metabolic demand. Continuous fulfillment of this energy demand depends on the ability of cells to sense, metabolize, and convert nutrients into chemical energy.
Detailed explanation-2: -The Plasma membrane maintains the homeostasis throughout a cell because it filters what substances go in and out of the cell. If there is too much of a substance in a cell the plasma membrane quickly disposes it and when there is not enough of a substance in a cell the plasma membrane lets the substance in.
Detailed explanation-3: -Exocytosis is a process in which a vacuole fuses with the cell membrane, releasing its contents to the outside of the cell. The membrane of the vesicle then becomes part of the cell’s plasma membrane, and the contents may enter a duct or the bloodstream.
Detailed explanation-4: -Organelles work together to maintain homeostasis by each performing different jobs that keep the cell alive. This division of labor helps keep the cell in balance, and different organelles rely on each other for their products. For example, the mitochondria make energy.
