how plant Harmon work
Answers
Plant cells produce hormones that affect even different regions of the cell producing the hormone. Hormones are transported within the plant by utilizing four types of movements. For localized movement, cytoplasmic streaming within cells and slow diffusion of ions and molecules between cells are utilized
Answer:
Gibberellins are hormones produced in meristems of stems and roots that help regulate stem elongation. Dwarf plants often do not contain much of this hormone and are therefore shorter than normal. Ethylene is a chemical produced in fruits, flowers and aging leaves that promotes fruit ripening.
EXAMPLE -
Plant hormones regulate plant growth, development, reproductive processes, longevity, and death. Six main types: Auxins, abscisic acid, cytokinins, ethylene gibberellin, and brassinosteroids. Recent additions: Jasmonates and strigolactones.
Plant Hormones -
When you hear the word 'hormones,' you may think of typical human hormones, such as testosterone, estrogen or even adrenaline. These hormones in our bodies regulate different physiological activities ranging from the tone of our voices to our height to our fight or flight response. Plants, which seem rather unresponsive most of the time, also have hormones to control physiological activities.
Hormones are chemical signals that coordinate the different parts of an organism. The word 'hormone' comes from a Greek term that means 'to excite.' These chemicals are produced in very small amounts in one area of an organism and are then sent to another part, where a response is triggered. Let's use the human hormone adrenaline to illustrate this. Our adrenal glands are located above our kidneys. They produce a hormone called adrenaline that, when needed, is transported through our bodies to cause an increase in heart rate, dilation of pupils and other responses to make us more alert.
Hormones in plants act in similar ways. They are produced by cells in one area of the plant - such as the leaves, stems or root - and then transported to a different area of the plant in order to produce a response. While the five major plant hormones we will look at sometimes have countless functions, we will focus on the main responses they trigger.
