A hormone is a chemical that affects the ways in which an organism functions; it is produced in one part of the plant (or animal) body but affects many other parts of the body as well. Hormones work by coming in contact with target cells, causing the organism to respond in various ways to the chemical signal. In plants, hormones usually work by influencing cell differentiation, elongation, and division. They also affect the timing of reproduction and germination. These hormones are divided int o five categories: auxins, cytokinins, gibberellins, inhibitors (or abscisic acid), and ethylene.

Do plant hormones effect the fertilizing of vegetables?
Plant hormones play a role in various aspects of plant development, including flowering and fruit setting in vegetables. However, the direct effect of plant hormones on fertilization is limited as fertilization mainly depends on pollination and the transfer of pollen to the stigma of the flower.
Define plant crop anatomy and physiology?
Plant crop anatomy is the study of how plants are structured. Plant crop physiology is the study of fundamental processes such as photosynthesis, respiration, plant nutrition, and hormones in plants.
Do organic or inorganic hormones help plants grow faster?
Organic hormones can help plants grow faster by promoting root growth, flowering, and fruit development. Inorganic hormones, such as synthetic plant growth regulators, can also accelerate plant growth by influencing specific physiological processes like cell enlargement and division. Both types of hormones can be effective, but the choice depends on the plant species and growth stage.
When a plant grows as mediated by growth hormones which main plant organs are at work?
When a plant grows in response to growth hormones, the main organs involved are the roots, stems, and leaves. Roots absorb water and nutrients from the soil, while stems support the plant and facilitate the transport of hormones and nutrients. Leaves are crucial for photosynthesis, producing energy that fuels growth. Together, these organs respond to growth hormones like auxins, gibberellins, and cytokinins to regulate various growth processes.
Auxins and giberellins are?
Auxins and gibberellins are plant hormones involved in regulating growth and development processes. Auxins are responsible for cell elongation, root formation, and apical dominance, while gibberellins promote stem elongation, seed germination, and flowering.
Is the hormones affected after the myomectomy?
yes
Communication between cells is affected if there is decreased ability to produce what?
Communication between cells is affected if there is decreased ability to produce signaling molecules such as hormones, neurotransmitters, or cytokines. These molecules are essential for transmitting messages between cells to regulate various physiological processes in the body.
What is the difference between the plant hormones and plant growth regulators?
Plant hormones are natural, created by the plants themselves. Plant growth regulators, on the other hand, are usually synthetic in nature. Both serve to help plants grow at low concentration, and both can damage plants at high concentrations.
How are plant hormones transported?
Plant hormones are transported through the plant by a combination of diffusion and active transport processes. They can move through cell walls, cell membranes, and the plant's vascular system to reach target tissues. Different hormones use different transport mechanisms depending on their chemical properties and target locations within the plant.
Why are plant hormones called messengers?
Plant hormones are called messengers because they play a crucial role in transmitting signals within the plant, coordinating growth, development, and responses to environmental stimuli. These chemical substances are produced in one part of the plant and can travel to other areas to elicit specific physiological responses, much like how hormones function in animals. By regulating processes such as cell division, elongation, and responses to stress, they effectively communicate information that helps the plant adapt and thrive.
Are cells without receptors affected by hormones?
no they are not
Is menstrual cycle is affected by hormones?
yes
