Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the balanced maintenance of an organism’s internal environment, allowing it to function effectively despite external changes.

Why do plants grow toward light?

Back

Plants grow toward light to maximize photosynthesis, which is essential for their growth and energy production.

Front

What role does the respiratory system play in homeostasis?

Back

The respiratory system takes in oxygen and releases carbon dioxide, maintaining the balance of gases necessary for survival.

Front

How does exercise affect heart rate?

Back

During exercise, the heart beats faster to provide muscle cells with extra oxygen needed for energy.

Front

Which organisms use homeostasis?

Back

All living things, including plants and animals, use homeostasis to maintain internal balance.

Front

What is the importance of maintaining a balance of oxygen and carbon dioxide?

Back

Maintaining a balance of oxygen and carbon dioxide is crucial for cellular respiration and overall survival.

Front

What is an example of a response to a change in the environment?

Back

A plant bending toward light is an example of a response to an environmental change to maintain homeostasis.

Front

What happens to the body when it gets too hot?

Back

When the body gets too hot, it sweats to cool down, helping to maintain a stable internal temperature.

Front

What is the function of the circulatory system in homeostasis?

Back

The circulatory system transports nutrients, gases, and waste products, helping to maintain internal balance.

Front

How do animals regulate their body temperature?

Back

Animals regulate their body temperature through behaviors like seeking shade or sunbathing, and physiological processes like sweating or shivering.
