Final answer:
Plasmodesmata are channels in plant cell walls that facilitate intercellular transport of materials, assisting in the distribution of water and nutrients throughout the plant.
Step-by-step explanation:
The channels in plant cell walls that allow for the transport of materials from one cell's cytoplasm to another's are known as plasmodesmata.
These channels are crucial for the plant's ability to transfer water, soil nutrients, and other substances from its roots, up through its stems, and into its leaves.
They work in conjunction with the vascular tissues, like the xylem and phloem, to ensure efficient transportation within the plant.
Plasmodesmata are the channels that pass between the cell walls of adjacent plant cells, allowing materials to be transported from cell to cell. These channels connect the cytoplasm of the cells, enabling the transfer of water and other nutrients throughout the plant.
