Help!! Plants, like animals and other organisms, must adapt to their changing environments. While animals are able to relocate from one
place to another when environmental conditions become unfavorable, plants are unable to do the same. Plants must deal with
changes in their environment in a different way. Plant tropisms are mechanisms plants use to respond to their environment. A
tropism is a growth toward or away from a stimulus. Common stimuli that influence plant growth include light, gravity, water, and
touch. Evaluate each of the tropisms. Select ALL of the choices that correctly pairs the type of tropism with its environmental
stimulus.
A)
phototropism: growth toward light
B)
hydrotropism: growth in response to water
C)
thigmotropism: growth in response to touch
D)
geotropism: growth in response to soil conditions
E)
thermotropism: growth in response to temperature
