It is because the enzymes in the plant are breaking down cellulose.
Provides the crop with protection from insects and parasites
Answer;
The substance that can enter a cell by diffusion without having to be digested is water.
Explanation;
Diffusion involves the movement of molecules from a region of high concentration to a region of low concentration, down a concentration gradient.
Water is able to diffuse through the cell membrane without being digested since it has small molecules.
One property of cell membrane is semi-permeability; it selectively allows material to enter or leave the cell. Large molecules such as starch , fat and proteins, can not enter the cell due to their size and will need to be digested to small molecules for the to gain access to the cell.
Autotrophs make their own food while heterotrophs do not; because of this, autotrophs may survive in certain situations in which heterotrophs would not.
Hope this helps.
The answer is One solution is to limit the scope of the study. Another possibility
is do several smaller studies over a longer period of time.
