Biology benchmark 2 semester exam fall 2 Select THREE ways that the sale membrane helps maintain homeostasis within a cell

Question

the cell membrane protects all of the organelles within the cell from injury
The cell membrane synthesizes proteins which helps maintain tissue structure
The cell membranes controls the concentration of organic molecules Ina cell's cytoplasm
The cell membrane allows water into and out of the cell
The cell membrane products enzymes that allow a cell to quickly carry out needed chemical reactions

Answer 1

To maintain homeostasis within a cell, the following three ways in which the cell membrane plays a crucial role can be highlighted:

1. The cell membrane controls the concentration of organic molecules in a cell's cytoplasm.
   This regulation ensures that the necessary nutrients and molecules are available within the cell for various metabolic processes while keeping out excess substances that could be harmful.

2. The cell membrane allows water into and out of the cell.
   This is essential for maintaining osmotic balance, which is crucial for cell function. The movement of water through the cell membrane through osmosis helps maintain the appropriate environment for organelles to function properly.

3. The cell membrane protects all of the organelles within the cell from injury.
   By acting as a protective barrier, the cell membrane helps maintain the integrity of the cell and prevents damage from external factors, thus preserving homeostasis.

The other statements regarding protein synthesis and enzyme production are not direct functions of the cell membrane itself; rather, these processes primarily occur in organelles like the ribosomes and endoplasmic reticulum.
