Cell Biology

Which of these is NOT a unique structure to plant cells?

• cell wall

• central vacuole

• chloroplas

• nucleus

What is the function of the cell nucleus found in both plant and animal cells?

• to produce energy
• to control cell activity
• to remove waste products
• to allow molecules to enter the cell

How do mitochondria regulate energy in a cell?

• Mitochondria transfer energy between cells as energy is needed.

• Mitochondria convert energy in nutrients into usable energy.

• Mitochondria absorb and convert energy from the sun.

• Mitochondria convert energy from the nucleus into usable energy.

Which of these is most commonly the largest structure inside an animal cell?

• endoplasm

• nucelus

• DNA

Which of these is NOT true of organelles(cell parts)?

• Organelles perform a certain function for a cell.

• Organelles are membrane-enclosed structures in a cell.

• Organelles are all the same inside a particular animal.

• Organelles are separated from the other parts of the cell.

Where do new cells come from?

• other cells

• nucleus

• Golgi body

• macrophages

All cells need energy (ATP) to function. Which cell organelle is responsible for producing energy in the cell? "The Powerhouse"
