2.1 Cell Structure and Function Quizs

Why do cells need energy?

• To carry out functions like growth, movement, and repair.

• To store information in DNA.

• To produce waste products efficiently.

• To maintain a constant temperature.

What is the function of the nucleus?

• The nucleus stores DNA and controls all cell activities by providing instructions to the cell.

• The nucleus is responsible for energy production in the cell.

• The nucleus helps in the synthesis of proteins.

• The nucleus regulates the movement of substances in and out of the cell.

What is the function of vacuoles?

• To produce energy for the cell

• To store water, nutrients, and waste, and help maintain pressure in plant cells

• To synthesize proteins

• To transport materials within the cell

What is a prokaryotic cell?

• A cell that has a nucleus and membrane-bound organelles.

• A cell that does not have a nucleus or membrane-bound organelles.

• A type of cell that is only found in plants.

• A cell that can perform photosynthesis.

What does the cell membrane do?

• It provides energy to the cell.

• It supports the cell and controls what can enter and leave; it is semi-permeable.

• It stores genetic information.

• It helps in cell division.

What do chloroplasts do in plant cells?

• Absorb sunlight and perform photosynthesis to make food (glucose).

• Store water and nutrients for the plant.

• Help in the respiration process of the plant.

• Provide structural support to the plant cell.

What is the function of ribosomes?

• Ribosomes produce energy for the cell.

• Ribosomes make proteins that the cell uses for growth and repair.

• Ribosomes transport nutrients across the cell membrane.

• Ribosomes are responsible for DNA replication.

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

• To provide energy for photosynthesis

• To give plant cells support, strength, and protection

• To store nutrients and waste products

• To facilitate cell division

What does the nuclear membrane do?

• It provides energy to the cell.

• It surrounds the nucleus and controls what enters and exits it.

• It helps in protein synthesis.

• It stores genetic information.

Why are mitochondria important to cells?

• Mitochondria provide energy by converting glucose and oxygen into usable energy.

• Mitochondria are responsible for protein synthesis in cells.

• Mitochondria help in the detoxification of harmful substances.

• Mitochondria store genetic information for the cell.
