Question

potatoes do not produce starch. yet they are full of it. how

Answer 1

starch is a carbohydrate, a compound made of carbon,oxygen and hydrogen. It is made by the plant for the storage of energy, kind of like we store fat in our bodies for energy reserves. 

Plants have leaves which capture energy from the sun, but the potato itself has no leaves.It is kind of like a bulb of a daffodil or onion in that it is the way that the plant survives over winter. It uses the stored energy in the starch for food [energy] until the newly growing plant is big enough so that the leaves can supply what it needs.

Answer 2

Yes, potatoes don't make any types of starch but still they are full of it.

It is because they get these starch by the process of photosynthesis. Starch

is a polymer formed by the monomer glucose. Potatoes serves as the storage organ of starch.

In the plant of potato, sugars gets turned into starch and then is transported to stem. The stem of the potato which is a modification growns inside the soil, i.e, underground.
