Cell Structure

Chromosomes are found in _____________________ of cells.

• the cytoplasm

• the nucleus

• the mitochondria

• the ribosomes

What is the function of the nucleus in a cell?

• It contains the cell's genetic material and controls its activities.

• It produces energy for the cell.

• It helps in the synthesis of proteins.

• It regulates the cell's water balance.

Prokaryotic cells have all of the following parts EXCEPT:

• Nuclear membrane

• Cell wall

• Ribosomes

• Plasma membrane

What is the function of the mitochondria?

• To produce energy for the cell through cellular respiration.

• To store genetic information.

• To synthesize proteins for the cell.

• To transport nutrients across the cell membrane.

What is the role of ribosomes in a cell?

• They are responsible for energy production.

• They are responsible for protein synthesis.

• They are responsible for DNA replication.

• They are responsible for cell division.

Why is the vacuole larger in a plant cell?

• For storage of food and holding shape

• To facilitate photosynthesis

• To store waste products

• To assist in cell division

What organelle is responsible for photosynthesis in plant cells?

• Mitochondria

• Chloroplasts

• Nucleus

• Ribosomes

The cell part found only in plant cells that provides support and structure to the cell is

• Cell membrane

• Cytoplasm

• Cell wall

• Nucleus

What is the purpose of the cell wall in plant cells?

• To provide energy for photosynthesis.

• To allow for cell division.

• To provide support and protection.

• To store nutrients.

What is the main difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus; eukaryotic cells do not.

• Prokaryotic cells are larger than eukaryotic cells.

• Prokaryotic cells do not have a nucleus; eukaryotic cells do.

• Prokaryotic cells have membrane-bound organelles; eukaryotic cells do not.
