Cell Structures and Organelles (Advanced Biology Chapter 4)

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that are the site of photosynthesis, converting light energy into chemical energy.

Front

What is the cytoskeleton?

Back

The cytoskeleton is a network of protein fibers that maintain the shape of the cell and assist in the movement of cell parts.

Front

Define cytoplasm.

Back

Cytoplasm is the semi-fluid matrix inside the cell (outside the nucleus) that contains organelles.

Front

Which organelle is found in both plant and animal cells?

Back

Mitochondria are found in both plant and animal cells and are responsible for energy production.

Front

What is the primary function of vacuoles in plant cells?

Back

Vacuoles are large storage organelles that are centrally located in plant cells, primarily used for storing nutrients and waste products.

Front

What is the role of mitochondria in the cell?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is the difference between plant and animal cells regarding cell walls?

Back

Plant cells have a rigid cell wall made of cellulose, while animal cells do not have a cell wall.

Front

What is the function of ribosomes?

Back

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

Front

What is the nucleus?

Back

The nucleus is the membrane-bound organelle that contains the cell's genetic material (DNA) and controls cellular activities.

Front

Define lysosomes.

Back

Lysosomes are organelles that contain digestive enzymes to break down waste materials and cellular debris.
