Plant Growth and Development: Key Hormones

Flashcards covering the main types of plant hormones and their roles in plant growth and development.

Auxins

Hormones responsible for cell elongation and crucial in phototropism.

Cytokinins

Hormones that promote cell division and are commonly found in areas of rapid growth such as root tips.

Ethylene

A hormone known for its role in fruit ripening and leaf abscission.

Gibberellins

Hormones that help in breaking seed dormancy and initiating germination.

Abscisic Acid

A hormone that plays a significant role in closing stomata during water stress.

Phytohormones

Chemicals that regulate plant growth and development.

Phototropism

The growth of plants towards light, primarily controlled by auxins.

Seed Germination

A process triggered by gibberellins that leads to the growth of a seed into a mature plant.

Stomata

Tiny openings on leaves that regulate gas exchange and water loss.
