Cell Organelles and Their Functions

The video explains the role of lysosomes as garbage disposal in animal cells and highlights that plant cells use vacuoles for similar functions. Vacuoles in plant cells store solid and liquid contents, providing turgidity and rigidity. They also store important substances like amino acids and sugars. In unicellular organisms, vacuoles help expel excess water and waste. The video also compares vacuole sizes, noting that plant vacuoles are much larger than those in animal cells.

Which organelle acts as the garbage disposal system in animal cells?

• Chloroplast

• Mitochondria

• Lysosome

• Vacuole

What is the primary function of vacuoles in plant cells?

• Energy production

• Storage of substances and waste disposal

• Protein synthesis

• Photosynthesis

In single-celled organisms like amoeba, what do vacuoles contain?

• DNA

• Food items

• Chlorophyll

• Enzymes

How do vacuoles contribute to the rigidity of plant cells?

• By synthesizing proteins

• By producing energy

• By providing turgidity

• By storing chlorophyll

What percentage of space can vacuoles occupy in some plant cells?

• 50 to 90 percent

• 10 to 20 percent

• 30 to 40 percent
