The tiny holes in the cell walls of plants that allow for the passing of materials are called the plasmodesmata. The correct option among the different options given in the question is the second option. Plasmodesmata are actually very small or rather microscopic channels that traverse the cell walls of the plant cells.
Plasmodesmata can be described as small channels ( or small holes) in the cell wall of adjacent plant and algal cell.
These channels allow the cytoplasm of adjacent cell to physically communicate with each other, thus allows the transport certain molecules ( such as proteins) from one cell to the adjacent cell through a symplastic pathway ( that is through the cytoplasm of the cells).
They are called ENZYMES. Enzymes speed up the rate at which the digestion process occur so that the nutrients in the food can be absorbed by the body and used for the development of the body.
