Vacuola

The video tutorial explains the role of vacuoles in plant cells, highlighting their function in storing substances like water, salts, and waste products. It also discusses the concept of turgor pressure, which is crucial for maintaining the shape and firmness of plant cells and tissues. Without turgor, plants would lose their structure, causing stems and leaves to wither.

What is one of the primary functions of the large vacuole in plant cells?

• To produce energy for the cell

• To store substances like water and salts

• To synthesize proteins

• To transport nutrients throughout the plant

Which of the following is NOT stored in the plant cell vacuole?

• Proteins

• Waste molecules

• Salts

• Water

How does the vacuole contribute to the plant cell's structure?

• By accumulating fluid that exerts pressure on the cell walls

• By generating energy for cell growth

• By synthesizing DNA

• By producing cell wall material

What is the term used to describe the pressure exerted by the vacuole on the cell walls?

• Photosynthesis

• Turgor

• Diffusion

• Osmosis

What would happen to plant cells without turgor pressure?

• They would become more rigid

• They would lose firmness and wither

• They would grow larger

• They would produce more chlorophyll
