Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain stable, constant conditions despite external changes.

Front

What role do receptors play in homeostasis?

Back

Receptors are specialized structures that detect changes in the environment (stimuli) and send signals to the control center to initiate a response.

Front

What is the function of the control center in homeostasis?

Back

The control center processes information received from receptors and determines the appropriate response to maintain homeostasis.

Front

What is an effector in the context of homeostasis?

Back

Effectors are organs or cells that carry out the response determined by the control center to restore balance in the body.

Front

What is the cell membrane's role in homeostasis?

Back

The cell membrane regulates what enters and leaves the cell, maintaining the internal environment necessary for cellular function.

Front

What is the endocrine system's function in homeostasis?

Back

The endocrine system controls growth and homeostasis by secreting hormones from glands that regulate various bodily functions.

Front

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

Back

The cell wall provides extra support and shape to plant cells, helping them maintain structure and resist external pressures.

Front

Which organelle is responsible for photosynthesis?

Back

Chloroplasts are the organelles in plant cells responsible for photosynthesis, converting light energy into chemical energy.

Front

What is the difference between plant and animal cells regarding organelles?

Back

Plant cells have a cell wall and chloroplasts, which are not found in animal cells; animal cells have centrioles, which are absent in plant cells.

Front

How do negative feedback mechanisms work in homeostasis?

Back

Negative feedback mechanisms counteract changes in the body by initiating responses that reverse the direction of the change, helping to maintain stability.
