describe the structure of chloroplast with the help of labelled diagram
Answers
"Chloroplasts are unique plant organelles which are about 4 to 6 microns in diameter and contain chlorophyll and are ""responsible for photosynthesis"". About ""30 to 40"" chloroplasts are found per mesophyll cell in the leaves of plants.
They are double membrane layered which are called the outer and inner membranes. These ""membranes"" are separated by an empty intermediate space. The interior of ""chloroplast is filled"" with a ""dense fluid"" called stroma which contains stacks of about 40 to 60 thylakoids which are called grana.
Thylakoids contain chlorophyll in their cavities which are called thylakoid spaces. The ""grana"" are ""connected"" by ""stromal lamellae"".
Apart from these, the stroma also contains nucleoids and starch granules.
