Question

question 3 a phagosome brings macromolecules into the cell and fuses with a lysosome; this is useful because lysosomes contain digestive enzymes. their own dna molecules. photosynthetic pigments. starch molecules for energy storage. cell waste materials.

Explanation:

Lysosomes contain digestive enzymes. When a phagosome fuses with a lysosome, the digestive enzymes in the lysosome are used to break down the macromolecules brought into the cell by the phagosome. DNA molecules are genetic material and not related to the immediate function of the lysosome - phagosome fusion. Photosynthetic pigments are related to photosynthesis in plant - related organelles like chloroplasts. Starch molecules are energy - storage molecules and not directly involved in the lysosome's digestive function in this context. Cell waste materials are the result of the digestion process rather than the components that make the lysosome useful in the fusion.

Answer:

digestive enzymes
