Question

what is the function of lysosomes within a cell?
they dispose of waste.
they synthesize proteins.
they generate energy.
they replicate dna.

Explanation:

Lysosomes are membrane - bound organelles that contain digestive enzymes. These enzymes break down waste materials, cellular debris, and foreign particles within the cell. Protein synthesis is mainly carried out by ribosomes. Energy generation occurs in mitochondria (through processes like cellular respiration). DNA replication takes place in the nucleus (for eukaryotic cells) during the cell cycle.

Answer:

They dispose of waste.
