Cell Organelles and Their Functions

This video lesson by Josh Patel covers Chapter 3, Lesson 2 on cell organelles. It explains the structure and function of eukaryotic cells, highlighting key organelles such as the nucleus, cytoskeleton, and endoplasmic reticulum. The lesson also discusses protein synthesis, the role of mitochondria in energy production, and the unique features of plant cells like cell walls and chloroplasts. The video concludes with a summary and a preview of the next lesson on cell membranes.

What is the primary function of the cytoskeleton in eukaryotic cells?

• To transport proteins

• To produce energy

• To support and shape the cell

• To store genetic information

Which organelle is known as the 'brain' of the cell?

• Golgi apparatus

• Nucleus

• To produce proteins

• To digest old organelles

How do ribosomes contribute to protein synthesis?

• By digesting materials

• By storing genetic information

• By converting solar energy

• By linking amino acids

What is the primary function of mitochondria?

What is the function of centrioles in the cell?

• To produce energy

• To aid in cell division

• To synthesize proteins

• To store water

Which structure is responsible for the rigid support in plant cells?

• Nucleus
