Cell Structures

What is the role of Chlorophyll in photosynthesis?

• Chlorophyll absorbs sunlight, which is essential for photosynthesis in chloroplasts.

• Chlorophyll releases oxygen as a byproduct of photosynthesis.

• Chlorophyll helps in the absorption of water from the soil.

• Chlorophyll converts carbon dioxide into glucose directly.

What is the function of Lysosomes?

• They store genetic information.

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

• They produce energy for the cell.

• They are involved in protein synthesis.

Do all types of cells have a cell membrane?

• Yes, all types of cells (plants, animals, bacteria) have a cell membrane.

• Only animal cells have a cell membrane.

• Only plant cells have a cell membrane.

• Bacteria do not have a cell membrane.

What is the role of the Nucleus in a cell?

• The Nucleus provides energy to the cell.

• The Nucleus directs all cell activities through the DNA located there.

• The Nucleus is responsible for protein synthesis.

• The Nucleus helps in the transport of materials within the cell.

What is the function of the Vacuole in plant cells?

• To perform photosynthesis

• To store nutrients and waste products, and help maintain turgor pressure

• To facilitate cellular respiration

• To synthesize proteins

What is the function of Mitochondria?

• Mitochondria are responsible for protein synthesis.

• Mitochondria are known as the powerhouse of the cell, generating energy through cellular respiration.

• Mitochondria help in the detoxification of harmful substances.

• Mitochondria are involved in the storage of genetic information.

What is Cytoplasm?

• A solid structure that provides support to the cell.

• A jelly-like substance within the cell membrane that contains organelles.

• A type of organelle responsible for energy production.

• The outer layer of the cell that protects it from the environment.

What is the difference between plant and animal cells?

• Plant cells have a cell wall and chloroplasts, while animal cells do not.

• Animal cells have a cell wall and chloroplasts, while plant cells do not.

• Both plant and animal cells have a cell wall and chloroplasts.

• Plant cells are smaller than animal cells.

What is the site of photosynthesis in plant cells?

• Chloroplast

• Mitochondria

• Nucleus

• Ribosome

What is the role of Ribosomes in a cell?

• Ribosomes are responsible for protein synthesis.

• Ribosomes are involved in DNA replication.

• Ribosomes help in cell division.

• Ribosomes store genetic information.
