Cellular Structures and Functions Unveiled

The video explains the structure and function of cell organelles, comparing prokaryotic and eukaryotic cells. It covers the roles of the cell membrane, cytoplasm, cytoskeleton, ribosomes, nucleus, endoplasmic reticulum, mitochondria, vacuoles, lysosomes, Golgi apparatus, chloroplasts, and cell wall. The video emphasizes the collaborative function of organelles to maintain cell life.

What is the main difference between prokaryotic and eukaryotic cells?

• Eukaryotic cells are smaller than prokaryotic cells.

• Prokaryotic cells have a nucleus, eukaryotic cells do not.

• Eukaryotic cells have membrane-bound organelles, prokaryotic cells do not.

• Prokaryotic cells are found in animals, eukaryotic cells are not.

What is the primary function of the cell membrane?

• To synthesize proteins.

• To produce energy for the cell.

• To control the movement of substances in and out of the cell.

• To store genetic material.

Which of the following is a function of the cytoplasm?

• It provides structural support to the cell.

• It stores water and nutrients.

• It facilitates the movement of organelles within the cell.

• It breaks down waste materials.

What role does the cytoskeleton play in a cell?

• It provides structural support and facilitates movement.

• It stores genetic information.

• It produces energy.

• It synthesizes proteins.

How do ribosomes contribute to cellular function?

• They synthesize proteins by linking amino acids.

• They break down waste products.

• They transport materials within the cell.

• They store energy for the cell.

What is the primary function of the nucleus in a cell?

• To synthesize lipids.

• To detoxify harmful substances.

• To store and protect genetic material.

• To produce energy.

What is the role of the rough endoplasmic reticulum?
