Front

What is the primary function of the cell membrane?

Back

The primary function of the cell membrane is to regulate the movement of substances into and out of the cell.

Front

Which organ system is responsible for gas exchange in the body?

Back

The respiratory system is responsible for gas exchange in the body.

Front

How do the circulatory and respiratory systems work together during exercise?

Back

The circulatory system distributes oxygen, while the respiratory system removes carbon dioxide from the body.

Front

What is the role of stomata in plants?

Back

Stomata open to allow carbon dioxide in for photosynthesis but also release water vapor, which can lead to wilting in dry conditions.

Front

What happens when homeostasis fails?

Back

When homeostasis fails, disease or death may occur.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is the function of the respiratory system?

Back

The function of the respiratory system is to facilitate gas exchange, providing oxygen to the body and removing carbon dioxide.

Front

What is the significance of photosynthesis in plants?

Back

Photosynthesis is the process by which plants convert light energy into chemical energy, producing glucose and oxygen.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen.

Front

What is the role of the circulatory system?

Back

The circulatory system transports nutrients, gases, hormones, and waste products throughout the body.
