The Cell: Vacuoles and Lysosomes

The video explains the roles of vacuoles and lysosomes in cells. Vacuoles store food, materials, and water, especially in plant cells. Lysosomes contain enzymes that break down large food particles and digest old cell parts. In tadpoles, lysosomes help digest tail cells, which are then reused to form new body parts as the tadpole matures into a frog.

What is the primary function of vacuoles in plant cells?

• To store water

• To synthesize proteins

• To transport nutrients

• To produce energy

Which organelle contains enzymes that break down large food particles?

• Ribosome

• Nucleus

• Chloroplast

• Lysosome

What happens to the smaller particles after lysosomes break down large food particles?

• They are converted into proteins

• They are used by mitochondria to produce energy

• They are expelled from the cell

• They are stored in the vacuoles

How do lysosomes contribute to the transformation of a tadpole into a frog?

• By providing energy for growth

• By digesting old tail cells

• By storing nutrients for development

• By producing new cells

What is the fate of the material from digested tail cells in a tadpole?

• It is discarded as waste

• It is used to form new body parts

• It is converted into energy

• It is stored in the vacuoles
