Cell Structure and Function

Click on the flashcard to see the answer

What is the main function of the cell membrane?

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

What is the role of the nucleus in a cell?

The nucleus serves as the control center of the cell, storing DNA and coordinating cell activities like growth and reproduction.

What are ribosomes responsible for?

Ribosomes are responsible for protein synthesis in the cell.

How do mitochondria function in the cell?

Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration.

What is the function of the endoplasmic reticulum?

The endoplasmic reticulum (ER) assists in the production and transport of proteins and lipids.

What does the Golgi apparatus do in a cell?

The Golgi apparatus modifies, sorts, and packages proteins for secretion or use within the cell.

What role do lysosomes play in a cell?

Lysosomes break down waste materials and cellular debris within the cell.

What is the function of chloroplasts in plant cells?

Chloroplasts conduct photosynthesis, converting solar energy into chemical energy stored in glucose.

How does the cytoskeleton contribute to cellular function?

The cytoskeleton provides structural support, aids in cell movement, and organizes the cell's contents.

What is a vacuole's function in a cell?

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

What distinguishes prokaryotic cells from eukaryotic cells?

Prokaryotic cells lack a nucleus and other membrane-bound organelles, unlike eukaryotic cells.

What role do cilia and flagella play in cells?

Cilia and flagella aid in cell movement and the transport of substances across the cell surface.

How do cells communicate with each other?

Cells communicate via chemical signals called ligands, which bind to receptors on the cell membrane.

What is the role of cell walls in plant cells?

Cell walls provide structure, protection, and support to plant cells and aid in regulating water intake.

What is the purpose of the cytoplasm?

Cytoplasm is the gel-like substance where organelles are suspended, facilitating cellular processes.
