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.

Answer:
a mycorrhiza
Explanation:
Mycorrhizae are mutualistic associations that occur between fungi and the roots of most vascular plants, which are those that have sap-carrying vessels.
Fungi increase the nutrient absorption capacity of plants while providing sugars and amino acids essential for the existence of fungi. That is, both (fungi and plants) are mutually beneficial. This is because fungi nourish plants and they, in turn, during photosynthesis produce carbohydrates that are assimilated by the fungi.
Mycorrhizae absorb nutrients from the soil and transmit them to plants. In this way, plants absorb water and mineral salts more easily and are therefore able to develop better and resist disease as well as climate change.
