<p>Chloroplasts are present in plant cells and contain thylakoid vesicles, which are the site of photosynthesis. They are responsible for converting light energy into chemical energy through the process of photosynthesis.</p> Signup and view all the answers

<p>The endoplasmic reticulum (ER) in eukaryotic cells is responsible for the synthesis, folding, and transport of proteins. The ribosomes are bound to the ER, where they translate mRNA into proteins.</p> Signup and view all the answers

<p>The thylakoid system in chloroplasts is a network of flattened, membrane-bound sacs called thylakoids. This is the site where the light-dependent reactions of photosynthesis occur, including the conversion of light energy into chemical energy in the form of ATP and NADPH.</p> Signup and view all the answers
