Do plant cells communicate using hormones?

Question

If so, how do those hormones travel between secreting cells and target cells?

Answer 1

They travel the same way food and water travel from the roots to the leaves and back again.

Yes they do. Cells communicate with each other via small, signaling molecules that are produced by specific cells and received by target cells. This communication system operates on both a local and long-distance level. The signaling molecules can be proteins, fatty acid derivatives, or gases. Nitric oxide is an example of a gas that is part of a locally based signaling system and is able to signal for a human's blood pressure to be lowered. Hormones are long-distance signaling molecules that must be transported via the circulatory system from their production site to their target cells. Plant cells, because of their rigid cell walls, have cytoplasmic bridges called plasmodesmata that allow cell-to-cell communication. Animals use gap junctions to transfer material between adjacent cells.

Answer 3

Of course Yes! It's called "cell-to-cell communication" or "cell signaling". Signals travel into cells, there are receptors that take the signals and signaling pathways are there for different cell types. This is a huge chapter topic, impossible to write down here. You could search the names I wrote and see what they are.
