Question: What term is used to describe a growth movement in plants?
The term used to describe a growth movement in plants is tropism. Tropism refers to the directional growth of a plant in response to external stimuli. Some common types include:
Phototropism – Growth towards or away from light (e.g., stems growing towards sunlight).
Geotropism (or Gravitropism) – Growth in response to gravity (e.g., roots growing downward).
Hydrotropism – Growth towards moisture (e.g., roots seeking water sources).
Thigmotropism – Growth in response to touch (e.g., vines wrapping around supports).
Chemotropism – Growth influenced by chemicals (e.g., pollen tube growing towards an ovule).
These movements help plants adapt to their environment for survival and reproduction.
