Which of the following best describes the role of vacuoles in plant cells?

• They synthesize proteins.

• They store water, nutrients, and waste products.

• They generate energy through photosynthesis.

• They transport molecules across the cell membrane.

What is the function of lysosomes in cellular waste management?

• They produce proteins for the cell.

• They digest and recycle cellular waste and worn-out organelles.

• They store genetic material.

• They provide energy for the cell.

Describe how the cell membrane's structure facilitates its role in homeostasis.

• Its rigid structure prevents any movement of substances.

• Its semi-permeable nature allows selective transport of substances.

• Its impermeable nature blocks all substances.

• Its flexible structure allows it to change shape easily.
