Tropism: meaning, definitions and examples
๐ฑ
tropism
[ หtrษสpษชzษm ]
biology response
Tropism is a biological phenomenon where organisms, such as plants, respond to external stimuli by growing or moving towards or away from that stimulus. This response can be triggered by various factors, including light (phototropism), gravity (gravitropism), and water (hydrotropism). Tropisms are crucial for a plant's survival as they help optimize conditions for growth and development. Understanding tropism can also provide insights into ecological interactions and adaptations.
Synonyms
growth reaction, movement, response
Examples of usage
- Plants exhibit phototropism by bending towards light.
- Roots display gravitropism by growing downward into the soil.
- Hydrotropism helps roots find water sources.
- Some flowers show thigmotropism by curling around supports.
- Tropisms ensure that plants maximize their exposure to resources.

Etymology
The term 'tropism' originates from the Greek word 'tropos,' meaning 'turn' or 'a turning.' It was first used in biological contexts in the late 19th century, particularly by botanist Charles Darwin, who studied how plants respond to various stimuli. The study of tropisms has evolved with advancements in biology and ecology, becoming an essential topic in understanding plant behavior and adaptation. Today, the concept extends beyond botany and is applied in various fields, including psychology and robotics, to describe directional growth or movement in response to stimuli.
