What is the function choroplast ? what is the function of golgi body ?

The Chloroplast contains chlorophyll which is responsible for turning sunlight into chemical energy during photosynthesis in plants. 

The Golgi body's job is to bundle proteins together so they can be later synthesized. 

The function of a chloroplast is to produce food for the plant
the function of a golgi body is to package, modify, and to transport proteins and lipids.

Used to water and cool climates, probably not thick coated or fluffy. they most likely have thin coats and have to survive to find food. sorry if this wasn't the answer you were looking for..: )
