Cells and Their Functions

Click on the flashcard to see the answer



What is the basic unit of life?

The cell is the basic unit of life.

What is the function of the cell membrane?

The cell membrane controls what enters and leaves the cell.

Name the part of the cell responsible for producing energy.

The mitochondria produce energy for the cell.

What is the role of the nucleus?

The nucleus contains the cell's genetic material and controls its activities.

What is the liquid inside the cell called?

The liquid inside the cell is called cytoplasm.

Which organelle is responsible for photosynthesis in plant cells?

Chloroplasts are responsible for photosynthesis in plant cells.

What is the function of ribosomes?

Ribosomes make proteins for the cell.

What is the main difference between plant and animal cells?

Plant cells have a cell wall and chloroplasts, while animal cells do not.

What do lysosomes do?

Lysosomes break down waste materials and cellular debris.

Name the structure that helps maintain cell shape.

The cytoskeleton helps maintain the cell's shape.

What is the function of the endoplasmic reticulum?

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

Describe the role of the Golgi apparatus.

The Golgi apparatus modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.

What is a vacuole?

A vacuole is a storage sac within cells, larger in plant cells.

Why are cells often called 'building blocks of life'?

Because they are the smallest functional units that make up all living organisms.

How do cells communicate with each other?

Cells communicate through chemical signals and receptors.
