What is the function of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, allowing it to obtain necessary items from the outside.

Front

What organelle is known as the powerhouse of the cell?

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

Back

The cell wall is a rigid outer layer that protects plant cells and provides structural support.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy in plants.

Front

What is the difference between the cell membrane and the cell wall?

Back

The cell membrane is flexible and controls the movement of substances, while the cell wall is rigid and provides structure and protection.

Front

What is the significance of lysosomes in a cell?

Back

Lysosomes contain enzymes that break down waste materials and cellular debris.

Front

How do cells maintain homeostasis?

Back

Cells maintain homeostasis by regulating their internal environment, including temperature, pH, and concentration of ions.

Front

What is the nucleus's role in a cell?

Back

The nucleus contains the cell's genetic material and controls its growth, metabolism, and reproduction.
