• store more chlorophyll

• absorb more water

All of the following describes the function of roots EXCEPT

Stomata are microscopic openings located on the underside of the leaf. One function of stomata is to -

• absorb water for the plant

• aid in the reproduction of the plant

• store glucose for photosynthesis

• allow gases to diffuse in and out of the plant

Auxin is a hormone that helps plants perform phototropism. The function of auxin is to

• cause the sunny side of the plant to grow so that the plant gets taller

• cause the shady side of the plant to shrink so that the sunny side can reach the light

• cause the sunny side of the plant to collapse to make the sun visible

• cause the shady side of the plant to grow so that the plant bends towards the light

Which of the following is NOT a function of the chloroplasts?

• using light energy to produce glucose

• using carbon dioxide to release oxygen

• using chlorophyll to to absorb light energy

• using oxygen to release carbon dioxide

Mosses are small flowerless plants that lack true roots and vascular tissue. Because of this, mosses are typically found near water sources so that they can conduct water by osmosis. Based on this description, which of the following is probably true of mosses.

• They have extra xylem and phloem.

• They form stems with thick cuticles.

• They grow close to the ground.

Plants must grow toward necessary resources such as light, as well as water and minerals found deep within the soil. The processes that allow plants to respond to these stimuli are known as

• mechanisms

• simulations

• tropisms
