Plant growth in response to a stimulus is called ................

• tropism

• cellular respiration

• photosynthesis

• transpiration

A change in direction of plant growth either toward or away from the light.

• phototropism

• positive gravitropism

• gravitropism

• geotropism

Change in the growth of a plant's root toward the center of the Earth or the force of gravity.

• Positive grvitropism

• phototropism

• positive phototropism

Change in the direction plant grows caused by gravity.

• gravitropism

• phototropism

What is tropism?

• A plant's response to a stimulus

• A plant reproducing

• An animal's response to a stimulus

• A prokaryote's response to a stimulus

Which of these are types of tropism? Select all that apply:

• Hydrotropism

• Synthetropism

• Gravitropism

True or False: a stimulus is anything that causes a plant to die

• True

• False

What is gravitropism/geotropism?

• The movement of a plant in response to gravity

• The movement of a plant in response to earthquakes

• The movement of bacteria in response to changes in temperature

• The movement of plants towards water

What is hydrotropism?

• The movement of plants towards water

• The movement of plants away from water

• The rate of growth of a plant in response to temperature changes in water

• A plant's response to gravity and touch

What is thigmotropism?

• The movement of plants in response to touch

• The movement of plants toward the sun

• A prokaryote's movement inside the bloodstream

• The movement of plants in response to gravity
