Auxin (plant hormone)

Auxin is a class of plant hormones that regulate various aspects of plant growth and development, including cell elongation, apical dominance, and responses to light and gravity. It plays a crucial role in processes such as phototropism and gravitropism by promoting differential growth in plant tissues.

Overview

Auxin is a vital plant hormone that plays a key role in regulating growth and development. It influences processes such as cell elongation, root formation, and responses to light, making it essential for healthy plant growth. Understanding auxin helps us appreciate how plants adapt to their environm...

Key Terms

Hormone
A chemical substance produced in the body that regulates physiological processes.

Example: Auxin is a hormone that regulates plant growth.

Cell Elongation
The process by which plant cells increase in length, contributing to overall plant growth.

Example: Auxin promotes cell elongation in stems.

Phototropism
The growth of a plant in response to light direction.

Example: Plants bend towards the light due to auxin distribution.

Apical Dominance
The phenomenon where the main central stem of the plant grows more strongly than the side stems.

Example: Auxin produced at the top of the plant inhibits growth of lateral buds.

Rooting Powder
A substance containing auxin used to promote root growth in cuttings.

Example: Gardeners use rooting powder to help plant cuttings develop roots.

Tropism
A growth response of a plant toward or away from a stimulus.

Example: Phototropism is a type of tropism where plants grow towards light.
