Cell structures

What is the significance of the cytoskeleton?

• It provides energy for cellular processes.

• It is involved in DNA replication.

• It provides structural support, helps maintain cell shape, and facilitates cell movement.

• It stores nutrients and waste products.

What is the role of enzymes in lysosomes?

• Enzymes in lysosomes synthesize proteins for the cell.

• Enzymes in lysosomes break down macromolecules, old cell parts, and microorganisms.

• Enzymes in lysosomes store nutrients for the cell.

• Enzymes in lysosomes transport substances across the cell membrane.

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

• The rough ER is involved in the production and folding of proteins.

• The rough ER is responsible for lipid synthesis.

• The rough ER plays a key role in energy production.

• The rough ER is involved in the detoxification of drugs.

What is the function of lysosomes in a cell?

• Lysosomes are responsible for digesting cell waste and cleaning up cellular debris, similar to waste management in a city.

• Lysosomes are involved in protein synthesis and ribosome production.

• Lysosomes help in the process of photosynthesis in plant cells.

• Lysosomes are responsible for energy production in the form of ATP.

What is the difference between prokaryotic and eukaryotic cells?

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

• Prokaryotic cells are larger and more complex than eukaryotic cells.

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

• Prokaryotic cells reproduce sexually, while eukaryotic cells reproduce asexually.

What role does the cell wall play in plant cells?

• It provides structure and support to plant cells.

• It allows for gas exchange in plant cells.

• It stores nutrients for plant cells.

• It aids in photosynthesis in plant cells.
