TROPISM

DIFFERENT TYPES OF TROPISM

• Gravitropism
• Chemotropism
• Phototropism
• Thermotropism
• Hydrotropism
• Thigmotropism

GRAVITROPISM

• Plants movement in response to gravity
• It can be positive-growing towards gravity
• It can be negative-growing away from gravity

CHEMOTROPISM

• Plants movement in response to chemicals
• Like for example a plant growing in response to fertilizer

PHOTOTROPISM

• Plants movement in response to light
• Sunflowers are examples because they move because of the light that's why they are called sunflower!

THERMOTROPISM

• Plants movement in response to temperature change
• When weather changes its movement may go faster or slower

HYDROTROPISM

• Plants movement in response to water
• Usually in river banks where there is erosion which removes part of it

THIGMOTROPISM

• Plants movement in response to touch
• Vines growing-positive
• Touch me nots-negitive
• Venus fly trap-positive
