The growth of a plant is their response to:

• tropism

• stimulus

• roots

Explain what tropism means:

Thigmotropism is a plant's response to:

Roots show positive gravitropism by growing:

• up

• in bundles

• down

• carefully

Plant hormones affect how plants______, and ________

Discuss the role of Auxin:

An example of tropism in plants would be:

• plants leaning toward the Sun

• multiple seeds being used to plant

• plants relying on photosynthesis

• release of oxygen

Plants exhibiting a response to light would be considered:

• gravitropism

• thigmotropism

• photosynthesis

• phototropism

An example of a negative stimulus response in plants would be:

• plants growing toward light

• plants moving away from light

• leaves falling off a tree

• stems wrapping around a railing

The anchoring of plants into the Earth would be related to:

• gravitropism

• phototropism

• thigmotropism

• leaves
