Abscisic acid (ABA) is a plant hormone that plays an essential role in the regulation of plant growth, development, and stress responses. It is involved in the regulation of seed dormancy, leaf senescence, and the response to environmental stresses, such as drought and cold. Abscisic acid is synthesized in many plant organs, including the leaves, …
Cytokinin is a plant hormone that promotes cell division and growth, as well as differentiation of different types of cells. It works by counteracting the effects of abscisic acid, which slows growth and development in plants. Cytokinin is produced in the root tips and the shoot apical meristem, and its production is increased by light. …
Auxin is a plant hormone involved in many plant processes, such as growth and development, cell division, phototropism, and apical dominance. Auxins are primarily synthesized in the apical meristems of shoots and roots, with some production in young leaves and flowers. They are then transported to other parts of the plant, including the roots, where …
Gibberellins are a group of plant hormones that play a major role in plant growth, development, and germination. They are involved in many different processes, such as stem elongation, cell division, flowering, seed germination, dormancy, root growth, and fruit development. Gibberellins are also known to stimulate the biosynthesis of several important plant molecules, such as …
Pheromones: These are chemical signals released by animals and plants to communicate with other individuals of the same species. Examples include androstenone released by male pigs to attract females, and citronellal released by queen termites to signal to others that she is the queen. Alarm substances: These are chemical signals released by some organisms to …

The hypothalamus is the key control centre of the endocrine system. It is responsible for coordinating the release of hormones from the pituitary gland, which is the master gland of the body. The hypothalamus sends chemical signals, called releasing hormones, to the pituitary gland when it needs to increase or decrease the release of a …
The hypothalamus and the pituitary gland have a close relationship and work together to regulate the body’s hormones. The hypothalamus is responsible for producing hormones that control the release of other hormones from the pituitary gland. These hormones from the hypothalamus are sent to the pituitary gland, which then releases a range of other hormones …
Progesterone plays a role in the development of sexual characteristics in both males and females. In males, it helps to regulate the production of testosterone, which is responsible for the development of male secondary sex characteristics, such as facial and body hair. In females, progesterone helps to regulate the menstrual cycle and is also responsible …
Estrogen is a hormone that plays a vital role in the development and maintenance of the female reproductive system. It is responsible for the development of female sexual characteristics, such as breasts and pubic hair, and it is also responsible for the regulation of the menstrual cycle. Estrogen also helps to maintain the health of …
