The plant cells communicate across cell walls through Plasmodesmata.
how do plant cells communicate across cell walls?
- Between tiny channels woven through the walls of neighboring plant cells, plant cells can communicate with one another through channels referred to as plasmodesmata.
- These channels enable chemicals to move freely between cells, allowing plants to grow regularly and form tissues and organs.
- However, plasmodesmata also act as entryways that viruses can employ to infect an increasing number of cells.
- Given these advantages and disadvantages, plants must balance the permeability of their plasmodesmata in order to move materials from one cell to another while preventing the spread of infection.
