The cell walls of plants and algae have openings, or channels. How is this structure most likely related to the functioning of a plant system? It provides further support to the cell by making the cell wall more rigid. It allows water and other molecules to enter and exit the system. It ensures that all the organelles receive an equal amount of sunlight.

It allows water and other molecules to enter and exit the system.

Explanation:

Plants have both a cell membrane and a cell wall. These allow needed molecules, such as water, to enter the cell. Both the cell wall and the cell membrane are semi permeable, which means that they choose what can enter and leave the cell. Molecules like water and other useful things to the cell enter it, and things such as waste leave the cell through the membrane and wall.

Remember that only plant cells have cell walls. Animal cells only have a cell membrane. But both the wall and membrane have the same purpose.

b would be the right answer

sorry, but you do not have posted the diagram.
