Set 3 – Mitochondria, Chloroplasts and Vacuoles

What is the function of mitochondria?

Site of respiration which provides energy.

Where are mitochondria plentiful?

In active cells such as muscle and nerve cells.

What surrounds a mitochondrion?

A double membrane.

Do mitochondria contain DNA?

Yes.

Why do active cells contain many mitochondria?

They need more energy.

Why do mature red blood cells lack mitochondria?

So they do not use the oxygen they transport.

What is the function of chloroplasts?

Site of photosynthesis.

What pigment do chloroplasts contain?

Chlorophyll.

What surrounds a chloroplast?

A double membrane.

Do chloroplasts contain DNA?

Yes.

What are two similarities between mitochondria and chloroplasts?

Both contain DNA and have a double membrane.

What is a vacuole?

A fluid-filled space surrounded by a membrane.

What is the function of vacuoles?

Storage of food and water and salts and gases and waste products.

Name three substances stored in vacuoles.

Water and sugars and salts.

Which cell has a large central vacuole?

A plant cell.
