Question

What is the composition of chloroplast?

Answer 1

Chloroplasts:

1. Chloroplasts are green-colored plastids present in plant cells that are responsible for photosynthesis (the process by which light energy is converted into chemical energy). They contain a photosynthetic pigment known as chlorophyll.
2. The chloroplasts are composed of lipids, proteins, carbohydrates, enzymes, and metallic atoms such as Fe (Iron), Cu (Copper), Zn (zinc), and Mn (Manganese).
3. 20-30% of the weight of chloroplasts is made up of lipids.
4. Chlorophyll is the green pigment that contains the metallic atoms of iron and magnesium.
