Homeostasis and Regulation in Animals and Plants

A collection of flashcards covering key concepts of homeostasis, regulation of body temperature, and plant transpiration.

What is homeostasis?

Homeostasis is the process by which living things maintain a stable internal environment.

How do cats and dogs regulate their body temperature?

Cats and dogs reduce body temperature by panting and sweating.

What role do sweat glands play in animals?

Sweat glands help in thermoregulation by releasing sweat to cool the body.

What is transpiration in plants?

Transpiration is the process by which plants lose water vapor through their leaves.

What happens to stomata during hot weather?

Stomata close to reduce water loss during high temperatures.

What is the corrective mechanism for an increase in body temperature?

The body increases blood flow to the skin, dilates blood vessels, and promotes sweating.

How does the body respond when temperatures drop?

The body shivers to generate heat and skeletal muscles contract to increase metabolism.

What is the significance of homeostasis to living organisms?

Homeostasis allows all the living processes in the body to function optimally.

What is the role of the hypothalamus?

The hypothalamus acts as the control center, regulating body temperature and other homeostatic processes.

How does the excretory system contribute to homeostasis?

The excretory system maintains water balance by regulating urine production.
