CHLOROPLAST

Explanation:

Chloroplast is a structure within the cells of plants and green algae, that is the site of photosynthesis (process by which light energy is converted to chemical energy). Chloroplasts are a type of plastid (a sack-like body involved in the synthesis and storage of foodstuffs). They are different from other plastids by their green coloration, which is as a result of the Chlorophyll A and B, whose function is to absorb light energy from the sun.

In plants, chloroplast occurs in all green tissues, although they are concentrated particularly in the parenchyma cells of the leaf mesophyll. The Chloroplast organnelle also possesses small circular chromosomes known as extranuclear DNA.

the unequal cytoplasmic division that  results  in  one egg  and three polar bodies ensures that a fertilized  egg has  ample nutrients  forits journey  to  the uterus.
