Homeostasis and Cell Processes

Front

What is the process by which a cell uses energy to surround a particle and enclose it in a vesicle?

Back

Endocytosis

Front

What must all cells do to survive?

Back

Obtain energy

Front

What is the movement of molecules from high concentrations to low concentrations called?

Back

Diffusion

Front

What happens to a cell if homeostasis is not maintained?

Back

Many chemical reactions in the cell will slow down or even stop.

Front

What does it mean for a cell membrane to be semi-permeable?

Back

It allows only certain particles to cross into or out of the cell.

Front

What is the process called when a cell expels materials in a vesicle?

Back

Exocytosis

Front

What is osmosis?

Back

The movement of water molecules across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

Why is energy important for cells?

Back

Cells need energy to perform essential functions such as growth, repair, and maintenance.

Front

What role do chemical reactions play in a cell?

Back

They are necessary for the cell to carry out its functions and maintain homeostasis.

Front

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.
