Both algae and plants store their food in the form of what?

Question

i narrowed it down to 4 answers

glycogen, proteins,cellulose, starch

Answer 1

The answer is Starch. Both plants and green algae store their food as starch.

Glycogen is used as a short term energy store in animal cells.

Proteins are not used to store food, they are things like enzymes etc which control vital processes in our bodies

Cellulose is the structural component of plant cell walls, but does not store food energy.

Hope this helps.
