Biology Cells as the Basis of Life: Cell Structure - Plant Cells Part 3

This video lesson covers the structure and function of plant cells, focusing on components like the nucleus, endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, chloroplasts, plasters, vacuole, and cytoskeleton. It explains how these organelles contribute to cell storage, structure, and energy transformation. The lesson also includes exam preparation tips and a review of key concepts.

• Photosynthesis

What is the composition of the vacuole's membrane?

• Double layer of proteins

• Single layer of phospholipids

• Double layer of phospholipids

• Single layer of proteins

How does the cytoskeleton contribute to the stability of plant cells?

• By storing nutrients

• By providing structural support

• By transporting lipids

• By synthesizing proteins

What are the fibers in the cytoskeleton made of?

• Lipids

• Carbohydrates

• Proteins
