How do the nutrients that enter our cells compare with the food we eat? A. The food we eat is broken down into individual, microscopic nutrient molecules which enter the cell. B. The nutrients that enter our cells are exactly the same as the food we eat, just smaller pieces. C. The nutrients that enter our cells are in the same form as the food we eat. D. The nutrients that enter our cells do not come from the food we eat.

Option-A

Explanation:

The cell requires nutrients for the growth, development and to survive. The body gets the nutrients from what we eat.

The food material eaten by humans has to be digested by the digestive enzymes or the complex molecules are broken down into the smaller molecules. These simple molecules are absorbed by the intestine through diffusion and get transported into the blood.  

From the blood, the nutrients reach to different cells of the body and hence are absorbed by the cell.

Thus, Option-A is correct.
