Cell Biology Flashcard

Front

What are prokaryotes?

Back

Prokaryotes are single-celled organisms that lack a nucleus and membrane-bound organelles. Examples include bacteria.

Front

What is the function of mitochondria?

Back

Mitochondria are organelles that convert chemical energy stored in food into ATP, which is used as energy by the cell.

Front

What organelle is found in plant cells but not in animal cells?

Back

Chloroplasts are found in plant cells and are responsible for photosynthesis, converting sunlight into chemical energy.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates the movement of materials into and out of the cell, maintaining homeostasis.

Front

Where is the dependent variable plotted in a graph?

Back

The dependent variable is plotted on the Y-Axis.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the structure of the cell membrane?

Back

The cell membrane is composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates.

Front

What is homeostasis?

Back

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

Front

What is the function of ribosomes?

Back

Ribosomes are the sites of protein synthesis in the cell, translating messenger RNA into polypeptides.
