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.
Hormones are signal molecules that travel through the bloodstream to target cells, where they bind to specific receptors to induce a physiological response.
A hormone is a chemical that your body makes.
A target cell is one of the cells that are effected by (a) hormone.
It find itself a hormone bow and a homone arrow, and hope he hits it right.
Only target cells have receptors inside cytoplazm (for steroid hormones) or on cell membrane (for protein hormones) that make the hormone active.

What is a cell that produces a signal molecule?
A cell that produces a signal molecule is known as a signaling cell or secreting cell. These cells release signaling molecules, such as hormones or neurotransmitters, which can travel to target cells to initiate a response.
What is the difference between Target cells and non-target cells?
Target cells are cells that have specific receptors for a hormone or external signal, allowing them to respond to the signal. Non-target cells do not have receptors for the hormone or signal, so they do not respond to it. Target cells are the primary sites of action for hormones, while non-target cells are unaffected by the hormone.
How do hormones travel to their targets in animal cells and in plant cells.?
In animal cells, hormones travel through the bloodstream to reach their target cells by binding to specific hormone receptors on the cell membrane or inside the cell. In plant cells, hormones can travel through vascular tissues in the plant or through cell-to-cell communication pathways to reach their target cells. Once at the target cell, hormones trigger specific cellular responses through signal transduction pathways.
What is the difference between an endocrine cell and a target cell?
An endocrine cell is a cell that secretes hormones into the bloodstream, while a target cell is a cell that has receptors for specific hormones and responds to them. Endocrine cells release hormones to signal target cells to carry out specific functions in the body.
Target cells are equipped with specific receptor molecules?
Yes, target cells possess specific receptor molecules on their surface that bind to signaling molecules such as hormones or neurotransmitters. This interaction triggers a cellular response or change in function within the target cell, influencing various physiological processes within the body.
What recognizes signal molecules such as growth factors and hormones?
receptors
Do hormones target molecules that originate outside the body?
no, pheromones do though.

Non-target cells do not have receptors for the hormone or signal, so they do not respond to it. Target cells are the primary sites of action for hormones, while non-target cells are unaffected by the hormone.
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
What is the chemical signal carried through the blood?
The chemical signal carried through the blood is primarily hormones. Hormones are produced by glands in the body and travel through the bloodstream to target specific cells or organs to regulate various physiological functions.
What is the difference between an endocrine cell and a target cell?
An endocrine cell is a cell that secretes hormones into the bloodstream, while a target cell is a cell that has receptors for specific hormones and responds to them. Endocrine cells release hormones to signal target cells to carry out specific functions in the body.
Target cells are equipped with specific receptor molecules?
Yes, target cells possess specific receptor molecules on their surface that bind to signaling molecules such as hormones or neurotransmitters. This interaction triggers a cellular response or change in function within the target cell, influencing various physiological processes within the body.
How do target organs most often regulate the pituitary gland?
Target organs regulate the pituitary gland through a feedback loop involving hormones. When a target organ senses a change in hormone levels, it can release specific hormones to signal the pituitary gland to either increase or decrease its production of certain hormones. This feedback mechanism helps maintain homeostasis in the body.
What is the difference between a hormone and a secondary messenger?
Hormones are signaling molecules secreted by glands into the bloodstream to target distant cells, while secondary messengers are molecules produced inside cells in response to hormone signaling, amplifying and transmitting the signal to the cell's interior. Hormones act at a distance, while secondary messengers act within the cell to relay and amplify signaling.
