Biology Cell Unit Review

What is the function of lysosomes in a cell?

• Lysosomes contain enzymes that break down waste materials and cellular debris.

• Lysosomes are responsible for protein synthesis in the cell.

• Lysosomes help in the production of energy in the form of ATP.

• Lysosomes are involved in the transport of nutrients across the cell membrane.

What is the role of the Golgi apparatus in a cell?

• It is responsible for energy production in the cell.

• It is responsible for packaging and shipping proteins and lipids within the cell.

• It is involved in the synthesis of DNA.

• It helps in the detoxification of harmful substances.

What is the structure and function of the cell membrane?

• The cell membrane is a rigid structure that provides support to the cell.

• The cell membrane is a phospholipid bilayer that protects the cell and regulates the movement of substances in and out of the cell.

• The cell membrane is a single layer of proteins that allows all substances to pass freely.

• The cell membrane is a carbohydrate layer that stores energy for the cell.

Explain the significance of ATP in cellular processes.

• ATP is a type of protein that helps in cell division.

• ATP is the primary energy carrier in cells, providing energy for various biochemical reactions.

• ATP is a waste product of cellular respiration.

• ATP is a vitamin that supports metabolic functions.

What is the role of ribosomes in a cell?

• Ribosomes are responsible for energy production in the cell.

• Ribosomes are responsible for protein synthesis in the cell.

• Ribosomes are responsible for DNA replication in the cell.

• Ribosomes are responsible for lipid synthesis in the cell.

What is one job that proteins do NOT have in the body?

• Storing genetic information.

• Transporting oxygen in the blood.

• Catalyzing biochemical reactions.

• Providing structural support to cells.

What is the importance of the cell cycle?

• It regulates the immune response in organisms.

• It is crucial for growth, development, and repair in organisms.

• It helps in the digestion of food in cells.

• It is responsible for the production of energy in cells.

What is the function of the endoplasmic reticulum (ER)?

• Involved in the synthesis of proteins and lipids, and transport of materials within the cell.

• Responsible for energy production in the cell.

• Involved in the breakdown of waste materials in the cell.

• Acts as a barrier to protect the cell from external factors.

What are the main differences between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus and membrane-bound organelles, while eukaryotic cells lack these features.

• Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and various organelles.

• Prokaryotic cells are larger than eukaryotic cells, which are smaller and simpler.

• Eukaryotic cells can reproduce asexually, while prokaryotic cells reproduce sexually.

Describe the process of cellular respiration.

• Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

• Cellular respiration occurs only in the presence of sunlight and produces glucose and oxygen.

• Cellular respiration is the process of converting energy from food into heat without producing any byproducts.

• Cellular respiration is a method used by plants to absorb nutrients from the soil.
