Biology Unit 5 Cell Function Practice

Front

What are the major structural components of the cell membrane?

Back

Phospholipids and proteins.

Front

What is the term for the body's ability to maintain a stable internal balance?

Back

Homeostasis.

Front

What organelle is primarily responsible for producing ATP in cells?

Back

Mitochondria.

Front

What happens to a cell in a hypertonic solution?

Back

It will lose water.

Front

What is the function of phospholipids in the cell membrane?

Back

They form a bilayer that acts as a barrier to protect the cell.

Front

Define homeostasis in biological terms.

Back

The process by which living organisms regulate their internal environment to maintain stable, constant conditions.

Front

What is mitosis and why is it important for cells?

Back

Mitosis is the process of cell division that results in two identical daughter cells, essential for growth and repair.

Front

What role do proteins play in the cell membrane?

Back

Proteins assist in transport, act as receptors, and provide structural support.

Front

What is the difference between a hypotonic and hypertonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the cell, while a hypertonic solution has a higher concentration.

Front

How does the structure of the cell membrane relate to its function?

Back

The fluid mosaic model describes the cell membrane's flexibility and the arrangement of proteins and lipids, allowing for selective permeability.
