Thylakoids - flattened membranous sacs forming the grana of chloroplasts

Vedclass · Answer

(A) : Thylakoids are the flattened sac-like membranous structures that are stacked on top of one another to form the grana of plant chloroplasts.Chlorophyll and other photosynthetic pigments are situated in the thylakoid membranes,which are the site for the light-dependent reactions of photosynthesis.$B$ is incorrect because centrioles are involved in spindle formation during cell division,not $RNA$ synthesis.$C$ is incorrect because chloroplast ribosomes are $70S$ and cytoplasmic ribosomes are $80S$.$D$ is incorrect because lysosomes contain hydrolytic enzymes that are optimally active at an acidic $pH$ (about $5.0$).
