Chapter 7 Cell Structure and Function Review

Front

What is the function of the Nucleus in a cell?

Back

The nucleus is the control center of the cell, containing the cell's genetic material (DNA) and regulating gene expression.

Front

What are the three main components of the Cell Theory?

Back

1. All living things are made of cells. 2. Cells are the basic unit of structure and function in all living things. 3. New cells come from existing cells.

Front

What is the role of Ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the function of Chloroplasts?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

Define Hypertonic solution.

Back

A hypertonic solution is one where the concentration of solute is greater outside the cell than inside, causing water to move out of the cell.

Front

What is the role of the Golgi Apparatus?

Back

The Golgi Apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the function of the Mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is the difference between a plant cell and an animal cell?

Back

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

Front

What is the function of the Cell Membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.

Front

What is a Vacuole?

Back

A vacuole is a storage organelle in cells that holds various substances, such as nutrients, waste products, or water.
