Plants With Seeds B. Tropism- a plant growing toward or away from a stimulus.
Plants With Seeds B. Tropism- a plant growing toward or away from a stimulus. 1. Positive tropism – plant grows toward the stimulus.
Plants With Seeds B. Tropism- a plant growing toward or away from a stimulus. 1. Positive tropism – plant grows toward the stimulus. 2. Negative tropism – plant grows away from stimulus.
Plants With Seeds B. Tropism- a plant growing toward or away from a stimulus. 1. Positive tropism – plant grows toward the stimulus. 2. Negative tropism – plant grows away from stimulus. 3. Examples:
Plants With Seeds 3. Examples:
Plants With Seeds 3. Examples: a. Phototropism = response to light – a positive tropism
Plants With Seeds 3. Examples: a. Phototropism = response to light – a positive tropism b. Gravitropism = response to gravity where roots show a positive tropism and stems show a negative tropism.
Positive Tropism Phototropism
Sunflower tropism
Negative tropism Charles Darwin was one of the first to scientifically document that roots show positive gravitropism and stems show negative gravitropism. That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards).
Example of Geotropism in the remaints of a cellar of a roman villa in the Archeologic Park in Baia, Italy
Negative tropism Gravity is used to signal root growth downwards and shoots upwards. (Shoots also use light (phototropism) to direct growth away from gravity.)
