A membrane-bounded organelle with chlorophyll containing membranous  thylakoids where photosynthesis takes place is called chloroplast.  A green pigment that absorbs solar eâ¦nergy and is important in algae  and plant photosynthesis is chlorophyll. Answered.
Mainly photosynthesis takes place in the palasede mesophyly. This is becouse chloroplasts are mainly concentrated in the palased mesophyl. Morover photosynthesis takes in other cells of the leaf eg, spongy mesophyl, and guard cells.hotosynthesis takes place in chloroplasts...which contain chlorophyll pigment,which is necessary for photosynthesis.misophyll cells of the leaf contain maximum number of chloroplasts...it is the main site of photosynthesis.
