Sweet potatoes and potatoes are both underground parts that store starch. How has this starch been made in them? Explain.
The word "starch" is taken from the Germanic root word meaning "strong, stiff, strengthen”.
It is an odorless, tasteless white substance that is manufactured in the green leaves of plants, from excess glucose produced during photosynthesis, and acts as a reserve food supply.
It is stored in the chloroplasts in the form of minute granules in the seeds, tubers, and other parts of plants, and forming an important constituent of rice, corn, wheat, beans, potatoes, and many other vegetable foods.
It is the most common carbohydrate in human diets which is contained in large amounts in staple foods.
The stem of the potato has undergone modifications in order to store food (starch) which is termed as stolons. Potato tubers (modified stems are usually called ‘tubers’) have buds that sprout stems and leaves from them while roots do not possess these properties.
The root of Sweet potato has undergone modifications in order to store the food (starch) that is also known as tuberous roots (modified roots are usually called ‘tuberous roots’ or ‘storage roots’).
