Homeostasis and Cell Processes (SC.6.L.14.3)

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

What role does the cell membrane play in homeostasis?

Back

The cell membrane regulates what enters and exits the cell, helping to maintain a stable internal environment.

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink and shrivel.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain substances to pass through while blocking others.

Front

What is the significance of sweating in maintaining homeostasis?

Back

Sweating helps cool the body down by releasing heat through evaporation, thus maintaining a stable internal temperature.

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy.

Front

What is the role of the cell wall in plant cells?

Back

The cell wall provides structure and support to plant cells, but it does not directly participate in maintaining homeostasis.
