Cell City

What is the function of the cytoplasm in a cell?

• The cytoplasm is the gel-like substance within the cell membrane that contains organelles and is the site for many metabolic processes.

• The cytoplasm is responsible for the synthesis of proteins only.

• The cytoplasm acts as a barrier to protect the cell from external damage.

• The cytoplasm is primarily involved in the storage of genetic material.

What organelle is known as the powerhouse of the cell?

• Nucleus

• Ribosome

• Mitochondria

• Endoplasmic Reticulum

What is the process by which chloroplasts convert sunlight into chemical energy?

• Photosynthesis

• Respiration

• Transpiration

• Fermentation

What is the function of lysosomes in a cell?

• Lysosomes contain digestive 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 through cellular respiration.

• Lysosomes store genetic information for the cell.

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

• It provides structural support and protection to plant cells, maintaining their shape and preventing excessive water uptake.

• It allows for the free movement of substances in and out of the cell.

• It stores nutrients and waste products for the cell.

• It facilitates photosynthesis by capturing sunlight.

How can the endoplasmic reticulum be described in relation to a cell's structure?

• A storage unit for genetic material.

• A network of roads that transport proteins and other materials throughout the cell.

• A protective barrier that surrounds the cell.

• A site for energy production within the cell.

What are organelles?

• Organelles are the basic units of life that can exist independently.

• Organelles are specialized structures within a cell that perform distinct processes necessary for the cell's function.

• Organelles are the genetic material found in the nucleus of a cell.

• Organelles are the outer membrane of a cell that protects it from the environment.

What is the role of the nucleus in a cell?

• It produces energy for the cell.

• It houses the cell's genetic material (DNA) and controls cellular activities by regulating gene expression.

• It helps in the synthesis of proteins.

• It is responsible for the cell's shape and structure.

What is the role of chloroplasts in plant cells?

• Chloroplasts absorb sunlight and convert it into energy for the plant.

• Chloroplasts absorb sunlight and use it to convert carbon dioxide and water into glucose through the process of photosynthesis.

• Chloroplasts are responsible for the respiration process in plant cells.

• Chloroplasts store nutrients and water for the plant.

What is the role of ribosomes in a cell?

• Ribosomes are responsible for energy production in the cell.

• Ribosomes are responsible for protein synthesis by translating messenger RNA into polypeptide chains.

• Ribosomes help in the replication of DNA.

• Ribosomes are involved in the transport of nutrients within the cell.
