Cell Biology Flashcard

Front

What is the function of lysosomes in a cell?

Back

Lysosomes act as the cell's waste disposal system, breaking down unwanted materials and recycling cellular components.

Front

What organelle is responsible for protein synthesis?

Back

Ribosomes are the organelles that synthesize proteins by translating messenger RNA.

Front

What is the main difference between cell membranes and cell walls?

Back

Cell walls are rigid structures found in plant cells, while cell membranes are flexible and found in both plant and animal cells.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts convert solar energy into chemical energy through the process of photosynthesis.

Front

What type of cell lacks a nucleus?

Back

Prokaryotic cells, such as bacteria, do not have a nucleus.

Front

What is the primary function of mitochondria?

Back

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

Front

What is the structure that contains the genetic material in eukaryotic cells?

Back

The nucleus contains the cell's genetic material (DNA) and controls cellular activities.

Front

What is the function of the endoplasmic reticulum?

Back

The endoplasmic reticulum is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), as well as detoxification.

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 role of vacuoles in plant cells?

Back

Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells.
