What is the primary function of a chloroplast in plant and algal cells?

Degrade macromolecules and worn-out organelles using hydrolytic enzymes in an acidic compartment

Generate ATP primarily through oxidative phosphorylation in the inner membrane

Modify, sort, and package proteins and lipids for secretion or delivery to other organelles

Convert light energy into chemical energy by carrying out photosynthesis, producing sugars and releasing oxygen
