Thigmotropism: the way a plant grows or bends because of touch (stimulus).

Example: Thigmotropism

Clematis are known for twining vines that revolve as they grow, making a full circle until they find an object to climb; this searching process is known as thigmotropism.

WRITE IN NOTEBOOK

Stimulus (changes) can be positive or negative.

Positive = toward stimulus Negative = away from stimulus

Positive Response

Plant moving toward stimulus(the sun).

Negative Response

Negative = roots growing away from sun.

The roots are growing AWAY from the sun because they need water for survival.

Draw (1 minute)
