Cell structures and Homeostasis (1)

Front

What is Homeostasis?

Back

The maintenance of a dynamic equilibrium for an organism to be stable and within the limits needed for survival.

Front

What is the function of Mitochondria?

Back

Creates energy (ATP) from food; site of cellular respiration.

Front

What is the function of Lysosomes?

Back

Uses enzymes to digest bacteria, viruses, and old organelles (old cell parts are recycled).

Front

What is a Feedback Mechanism?

Back

Biological reactions that change a system to return the body to homeostasis.

Front

What is the function of Chloroplasts?

Back

Site of photosynthesis; uses the sun's energy to produce food.

Front

What is the role of the Cell Membrane?

Back

Regulates what enters and leaves the cell; provides protection and support.

Front

What is the function of the Nucleus?

Back

Controls cell activities and contains genetic material (DNA).

Front

What is the role of Ribosomes?

Back

Site of protein synthesis; can be found free in the cytoplasm or attached to the endoplasmic reticulum.

Front

What is the function of the Endoplasmic Reticulum (ER)?

Back

Transports materials within the cell; rough ER has ribosomes for protein synthesis, while smooth ER is involved in lipid synthesis.

Front

What is the role of the Golgi Apparatus?

Back

Modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
