Explain how starch in the sweet potato is produced from carbon dioxide in the air thanks

You will already know about photosynthesis and how that is almost the only way that new energy can enter the world of living things. All plants and animals rely on photosynthesis for their supply of energy.

You also know that starch is an important energy food for YOU (think of all the starchy foods you eat as well as potatoes!).

So, you might have guessed that the starch in the potato comes from photosynthesis. (In fact, starch is a big molecule (polymer) made up from many glucose molecules linked together).

Now, where is glucose made in the plant?

What links those parts to the growing potato tuber? There are two transport systems in plants, one for water/minerals and one for sugars - look in your text book to find which is which.

You should also ask yourself "Why does the potato store STARCH and not GLUCOSE?" - this explains why the energy is transported as glucose (actually as the closely related sucrose), yet deposited in potatoes for storage as starch.
