Cell Structure and Function

What is the function of the cell membrane?

• Controls the movement of substances in and out of the cell.

• Stores genetic information

• Provides energy to the cell

• Regulates cell division

Which organelle is responsible for photosynthesis in plant cells?

• Chloroplast

• Endoplasmic reticulum

• Mitochondria

• Nucleus

What is the role of mitochondria in a cell?

• Produces ATP through cellular respiration

• Synthesizes proteins

• Stores genetic material

• Regulates cell division

What is the main function of the nucleus?

• Produce energy for the cell

• Regulate cell division

• Synthesize proteins

• Control cell activities and store genetic material

What is the primary component of a plant cell wall?

• Starch

• Lipid

• Cellulose

• Protein

What is the function of cytoplasm in a cell?

• Regulates cell division

• Synthesizes proteins

• Acts as a medium for organelles to float in

• Stores genetic material

Describe the structure of the cell membrane.

• The cell membrane is a single layer of proteins

• The cell membrane is made of carbohydrates only

• The cell membrane is a phospholipid bilayer with embedded proteins.

• The cell membrane is a rigid structure with no flexibility

Explain the function of chloroplasts in plant cells.

• Chloroplasts function in waste removal by expelling toxins from the cell.

• Chloroplasts function in photosynthesis by converting light energy into chemical energy.

• Chloroplasts function in cell division by producing new organelles.

• Chloroplasts function in cellular respiration by breaking down glucose.

How do mitochondria contribute to cellular energy production?

• Mitochondria produce ATP through cellular respiration.

• Mitochondria release energy through photosynthesis.

• Mitochondria contribute to cellular energy production by storing glucose.

• Mitochondria store energy in the form of lipids.

Why is the nucleus considered the control center of the cell?

• It controls the movement of the cell.

• It stores water and nutrients for the cell.

• It contains the genetic material (DNA) that regulates cellular activities.

• It is responsible for producing energy in the cell.
