Answer:
1. Signaling molecule
2. Signaling receptors
Explanation:
Hormones, growth factors, neurotransmitters, etc. serve the function of signaling molecules for cells. These molecules are released by one cell and bind to the receptors present on/in the target cells to elicit the desired response. Thereby, the signaling molecules serve in cell-cell communication.
For example, insulin hormone synthesized and released from beta cells of pancreas binds to its cell surface receptors present on the surfaces of liver cells and muscle cells to stimulate the uptake of the glucose from the blood.
Likewise, neurotransmitters released from the presynaptic neuron bind to receptors present on the membrane of postsynaptic neuron and serve to carry the nerve impulse to the postsynaptic neuron.

Most likely, it would effect many trees depending on the rate of infection and how much of this microorganism is released to the environment. I hope that helped :)
Answer:
1) Plant tissue has a stationary phase.
2) They do not necessitate a large amount of energy
3) They have more dead cells because mechanical energy is produced.
4) They are capable of preparing their own meals
5) They are divided into two categories: meristematic and permanent tissue.
Tissue from animals:
1) They're at the locamative stage.
2) They need a significant amount of energy
3) They have a higher number of live cells.
4) They are unable to produce their own food and must rely on other organisms.
5) They are classified into four types: epithelial, connective, muscular, and nervous tissue.
