Can we survive on raw leafy vegetables

Can we survive only on raw, leafy vegetables/grass? Discuss.

No.Humans cannot survive only on raw, leafy vegetables, or grass. It is because the grass is rich in cellulose, which is a type of carbohydrate that humans are not able to digest due to the absence of cellulose-digesting enzymes

We know that the animals, fungi, bacteria, non-green plants and human being do not have the ability to make their own food. They depend upon autotrophs for their food directly or indirectly. The green plant (leafy vegetables/grass) trap solar energy and make their own food in the form of glucose. So, we can say that leafy vegetables and grass can provide sufficient energy to help us survive.

Solution : No.Humans cannot survive only on raw, leafy vegetables, or grass. It is because the grass is rich in cellulose, which is a type of carbohydrate that humans are not able to digest due to the absence of cellulose digesting enzymes.

Q.13 Can we survive only on raw, leafy vegetables/grass? Discuss.

Answer :

No, we cannot survive only on raw, leafy vegetables because :

1.They mainly consist of Cellulose which cannot be digested by us due to lack of cellulose digesting enzyme in our body.
2. We cannot get all required nutrients, such as carbohydrates, proteins, lipids, vitamins, and minerals, from them.
3. Moreover raw vegetables may not be digested easily as compared to cooked vegetables.

Question 13Can we survive only on raw, leafy vegetables/grass? Discuss.

Solution

Raw leafy vegetables and grass are rich in cellulose, a type of carbohydrate. Many animals including humans cannot digest cellulose because they do not have enzymes and the bacteria which can digest cellulose. We cannot survive by taking vegetables in the raw form. That's why we boil or cook vegetables which breaks down cellulose into simple carbohydrates. We can only survive by taking in vegetables in the boiled or cooked form.
