Hormones affect target cells because target cells have receptors that bind with certain hormones (they're specific). If a cell does not have a receptor then it is not affected by hormones. Target cells (which do have the receptor for a particular hormone) would be affected by the hormone.

How do hormones travel to their targets in animal cells and in plant cells.?
The process is different for plants and animals. In animals, the hormones are transported by the circulatory system, which eventually allows them to reach the target cells with appropriate receptors. In plants, the hormones are signal molecules, and they're not produced in large concentrations; they regulate targeted cellular processes in the plant that produces them.
Why hormones can contact virtually all the cells of your body yet only activate the appropiate target cells?
The receptor molecules have the " lock " that the " key " of the hormone fits into . Surface markers, generally glycoproteins, must match up for the hormone to dock at the cell and a signal transduction pathway is then initiated.
Why do lipid soluble signaling molecules like testosterone cross membranes of all cells but effect only target cells?
Because response of a cell to a signaling requires that the responding cell have receptors that recognize that hormone. Only target cells of a signal have the receptors for the signal.
What materials are expelled from cells during exocytosis?
Food molecules and waste material
Hormones affect specific tissues called?
Hormones work by affecting Target Organs
What recognizes signal molecules such as growth factors and hormones?
receptors
Do hormones target molecules that originate outside the body?
no, pheromones do though.
What system releases signal molecules into the bloodstream?
endocrine glands.

What does the organs influenced by hormones are called?
They are the target organs. Hormones act on the target organs

Receptors allow hormones to bind to their target cells.

What are hormones carried in to their target cell?
Hormones are chemcial messengers released into the blood stream to be carried through out the body to target cells.
Where do hormone go?
hormones go to there target cells or target organs
