Plant growth regulators, also known as phytohormones, are organic compounds produced naturally in plants to control growth and physiological functions. They include auxins, gibberellins, cytokinins, ethylene, growth regulators, and inhibitors. Auxins, for example, promote growth along the plant's lo

Cutaneous circulation plays a vital role in supplying blood to the skin, with variations in apical and non-apical regions of the body. The blood flow is regulated by neural, thermal, and metabolic factors, and controlled by sympathetic fibers. Sympathetic vasoconstriction and vasodilation affect the

Plant growth regulators, also known as plant hormones, play a crucial role in regulating growth and development in plants. They are organic compounds that act at low concentrations to promote, inhibit, or modify growth processes. The main plant hormones include auxins, cytokinins, gibberellins, absc

Plant tissues are groups of cells with similar structures and functions. They can be classified into meristematic, permanent, and secretory tissues. Meristems are regions of continuous cell division found in plant tips and cambium, essential for growth. Primary meristems are present from the embryo
