Exploring Cell Structures

What is the main function of the cell membrane?

• To provide structural support to the cell

• To facilitate protein synthesis

• The main function of the cell membrane is to control the movement of substances in and out of the cell.

• To store genetic information

Describe the role of the nucleus in a cell.

• The nucleus produces energy for the cell.

• The nucleus controls cellular activities and stores genetic information.

• The nucleus is responsible for protein synthesis.

• The nucleus transports nutrients within the cell.

What is the primary function of mitochondria?

• Mitochondria are involved in the synthesis of lipids.

• Mitochondria help in the breakdown of harmful substances.

• Mitochondria generates energy through various reactions

• Mitochondria assist in the replication of DNA.

What are ribosomes responsible for in a cell?

• Ribosomes are responsible for synthesizing DNA.

• Ribosomes store genetic information for the cell.

• Ribosomes are responsible for synthesizing Proteins.

• Ribosomes transport material through the cell membrane.

Explain the function of chloroplasts in plant cells.

• Chloroplasts help in the absorption of minerals from the soil.

• Chloroplasts are responsible for cellular respiration in plant cells.

• Chloroplasts store water and nutrients for the plant.

• Chloroplasts function to conduct photosynthesis, converting sunlight into glucose and producing oxygen.

What is cytoplasm and what does it contain?

• Cytoplasm is the nucleus of the cell that contains DNA and RNA.

• Cytoplasm is the outer membrane of the cell that protects it from the environment.

• Cytoplasm is the gel-like substance in a cell that contains water, salts, organic molecules, and organelles.

• Cytoplasm is a solid structure that only contains proteins.

How does the structure of the cell membrane affect its function?

• The cell membrane is rigid and does not allow any substances to pass through.

• The structure of the cell membrane is gel-like and allow all the substances to pass through it.

• The cell membrane's main function is to store genetic information.

• The structure of the cell membrane is porous and only allow selective materials to pass through it.

What would happen to a cell without a nucleus?

• The cell would develop a new nucleus.

• The cell would become more efficient at energy production.

• The cell would thrive and grow larger.

• The cell would be unable to function properly and would likely die.

Why are mitochondria often referred to as the powerhouse of the cell?

• Mitochondria are involved in detoxifying harmful substances.

• Mitochondria store genetic information for the cell.

• Mitochondria are responsible for protein synthesis.

• Mitochondria are referred to as the powerhouse of the cell because they generate energy for cellular activities.

How do vacuoles contribute to plant cell function?

• Vacuoles provide structural support and store substances such as water and nutrients.

• Vacuoles are responsible for photosynthesis.

• Vacuoles transport proteins within the cell.

• Vacuoles generate energy for the cell.
