How does a chloroplast help maintain homeostasis?

Answer 1

plants need to regulate water loss and carbon dioxide intake for photosynthesis and other life activities

when plants do not keep enough water in their cells, they wilt and die

stomate: a microscopic hole in a plant leaf which allows gases to enter and leave and water vapor to leave as well.

guard cells: open and close the stomate.

the ability of the guard cell to close during periods of limited water availability for the plant allows the plant to maintain water homeostasis.

There are many factors that govern the homeostasis. For example microRNAs are known to regulate auxin homeostasis in plants. If you didn't understand what I meant ... just realize that there are many proteins and RNAs inside the cell that regulates what needs to be taken into the cell and what should not be ... there by maintaining homeostasis.

But of course diffusion and osmosis also occurs within a cell to maintain homeostasis, thoguh due to the plant cell wall, this is limited.

Osmosis is the net movement of water (concentrate on the word water) across aselectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane. A selectively permiable membrane is one that allows unrestricted passage of water, but not solute molecules or ions.

Diffusion - the process by which molecules (concentrate on the word molecule) spread from areas of high concentratiion, to areas of low concentration. When the molecules are even throughout a space - it is called EQUILIBRIUM

Answer 2

Photosynthesis is one of the most important phenomenon in nature. It fixes the radiation energy present in the sunlight into chemical energy that could be used by other organisms (animals) also.

Each organism could be compared to a vehicle. Any vehicle needs energy and the energy is provided by the combustion of fuel. In the same way, any plant (and animal also) require energy that comes from the catalytic breakdown of a small molecule. The classical molecule that is used by plants is glucose. Glucose undergoes a series of reaction and the energy in the chemical bonds is then stored in the phospodiester bond of the ATP molecules. These ATP molecules then release the energy whenever required.

The glucose molecule is itself formed by the the fixation of atmospheric CO2 after series of reactions. Thus if no photosynthesis will occur then the plant would die off the starvation.

Answer 3

they make the food for the cell so the cell can be balanced and function properly!

Answer 4

These are exothermic reactions, hence cause production of heat in the body, which helps in maintenance of normal body temperature, and so maintain homeostasis.

Answer 5

photosynthesis help plant maintain so many food n shether
