Explanation:

Hormones, generally, are chemicals produced in a specific part of an organism in order to bring about a physiological change in another part. Hormones produced by plants are classified into the following: Auxins, Gibberellins, Cytokinins, Ethylene, and Abscisic acid. They effect the following major functions in plants:

- Gibberellins: These are hormones produced by plants that stimulate stem elongation, seed germination, and flowering.

- Abscisic acid: These are hormones that regulates survival functions of a plant such as the opening and closing of stomata.

- Cytokinins: These are chemicals/hormones that helps plant cells divide.

- Ethylene: These are hormones that promotes ripening of fruit or blooming of flowers.

- Auxins: These are chemicals or hormones produced in plants that are characterized by their ability to induce cell elongation and cell division in stems.

relationships play a major role in a human's emotional and mental wellbeing. healthy relationships with the people around you are even linked to a smaller production of cortisol, a stress hormone.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
