Chapter 7 Cell Structure and Function Review

Front

What is the main difference between plant and animal cells?

Back

Plant cells have a cell wall and chloroplasts, while animal cells do not.

Front

What happens to a cell in a hypotonic solution?

Back

Water rushes into the cell, causing it to swell.

Front

What are the three main principles of the cell theory?

Back

1. Cells are the basic units of life. 2. All living things are made of cells. 3. All cells come from existing cells.

Front

What is the function of the cell wall?

Back

The cell wall provides structure and protection to plant cells.

Front

Define isotonic solution.

Back

An isotonic solution has equal concentrations of solute and water on both sides of a membrane.

Front

What organelle is responsible for energy production in cells?

Back

Mitochondria.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting sunlight into energy.

Front

What is the function of the large central vacuole in plant cells?

Back

The large central vacuole stores water, nutrients, and waste products.

Front

What is the difference between hypertonic and hypotonic solutions?

Back

Hypertonic solutions have a higher concentration of solute compared to the cell, while hypotonic solutions have a lower concentration.

Front

What is the primary function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell.
