The present article describes various subcellular changes occurring during development and maturation of the mesocarp of Asclepias curassavica follicle. The ground tissue of the ovary wall consists of dense cytoplasm containing cell organelles like mitochondria, endoplasmic reticulum, chloroplast, ribosomes etc. Mesocarp developing from the ground tissue is differentiated into three zones on the basis of cell shape and degree of vacuolation. Chloroplasts possess starch grains which have a central electron translucent area and a peripheral electron opaque boundary. In the mature fruit the mesocarpic cells are highly vacuolated with a peripheral layer of cytoplasm. The cytoplasm seems to be loose or less denser than that of the developing mesocarpic cells, but contains all the cell organelles that are present in the developing mesocarp.
