Saclike membranes having chlorophyll are known as THYLACOIDS, GRANA is a stack of thylakoids. Moreover, STROMA is the fluid outside of the thylakoids, and two MEMBRANES surround and enclose the chloroplasts.
Chloroplasts are organelles found in plants and algae involved in photosynthesis.
Photosynthesis is a series of metabolic reactions by which plant/algae cells use the energy from the sun and carbon dioxide to generate simple carbohydrates (sugars) and oxygen.
The light-independent photosynthetic reactions occur in the stroma of the chloroplasts, whereas the light-dependent reactions occur in the thylakoid membranes.
