The main role of chloroplast is to conduct photosynthesis
Explanation:Chloroplasts are specialised organelles characterised by their high concentration of chlorophyll. They convert light energy into chemical energy by photosynthesis.
Chloroplast carry out a number of other functions including fatty acid synthesis, some amino acid synthesis and the immune response in plants.
Chloroplasts along with the nucleus, cell membrane, and endoplasmic reticulum participate in the plant immune response.
They make all of the cell's purine and pyrimdines.
They also convert nitrite into ammonia, which supplies the plant with nitrogen.
Chloroplasts are highly dynamic, they circulate and are moved around within plant cells and occasionally pinch into two to reproduce.
