- Protein and starch
- Carbohydrate and protein
- Polysaccharide and protein
- Starch and lipid
The correct answer is: Protein and starch
Protein and starch.
Green algae store food in form of starch in specialized structures called pyrenoids located in chloroplast. Each pyrenoid has a central protein called ‘pyrenocrystal’ and a surrounding starch sheath
