Auxins are plant hormones that play a crucial role in regulating plant growth and development. One of their main functions is to promote cell division in the apical meristem of young plants, which is the area of the plant responsible for growth in length. Auxins also help control plant growth orientation, and promote the formation of roots and fruits.

Gibberellins are a group of plant hormones that regulate various growth and developmental processes in plants. While they play essential roles in stem elongation, seed germination, and flowering, they are not primarily responsible for cell division in the apical meristem.

Ethylene is a plant hormone that is involved in regulating fruit ripening, senescence (aging), and response to stress. While it influences various aspects of plant growth, it is not the main hormone responsible for cell division in the apical meristem.

Cytokinins are plant hormones that primarily promote cell division and growth. They play a crucial role in stimulating cell division in the apical meristem. While cytokinins are primarily known for their role in promoting cell division, auxin works with cytokinins to regulate cell division and differentiation in the apical meristem. Auxin helps balance cell division and differentiation, ensuring proper growth and development of new tissues and organs.

Abscisic acid, or ABA, is a plant hormone involved in stress responses, seed dormancy, and stomatal closure. It regulates water loss in plants and plays a role in maintaining water balance during environmental stresses. It is not directly associated with cell division in the apical meristem.
