sites of action
Skin and Internal tissues. Not in the nervous tissue of the brain, which lack of pain receptors.
The skin includes sensory receptors, protects other tissues, and insulates the body against temperature changes.
when the chemicals arrive in the right places, the target tissues, they start to do their work. a group of cells that have receptors embedded in the plasma membrane that are complementary in shape to specific hormone molecules. Only these cells will respond to that specific hormone.
Non-meristematic plant tissues are classified as either simple tissues (containing only one type of cell) or as complex tissues (containing multiple types of cells) There are three types of simple tissues: 1. Parenchyma 2. Collenchyma 3. Sclerenchyma
Proteins are the building blocks of most tissues and nearly all receptors.

The xylem tissues, though dead, conduct water from the roots throughout the plant, especially into the leaves. The phloem conducts the finished sugars made from photosynthesis throughout the plant to wherever they are needed.
A living cell is the smallest structure of that carries out specific functions.
The iron-containing pigment of the erythrocytes that transports oxygen from the lungs to all of the body tissues would be "Hemoglobin".
