Both Land Plants and Algae Use Starch as a Storage

Both land plants and algae use starch as a storage medium and cellulose in their cell walls.The best conclusion that can be drawn from this observation is that

A) they both produce glucose since this is the molecule that both starch and cellulose are made from.
B) they both use chlorophyll as a photosynthetic pigment.
C) they both use tubers to store starch and they both use the same enzymes to make cellulose.
D) they both produce galactose,which gives rise to maltose the molecule that both starch and cellulose are made from.
E) if algae are transported to land they will be able to survive the same as a land plant.
