Unit 8b Review

Which structure controls water loss in plants?

• Xylen

• Phloem

• Stomata

• Roots

During a drought, stomata will mostly...

• open wider.

• close to reduce water loss.

• produce sugar.

• absorb minerals.

What does xylem transport?

• Sugar

• Oxygen

• Water

• Carbon dioxide

Growth toward light is called:

• phototropism

• thigmotrp[ism

• geotropism

• hydrotropism

Which part of the plant detects light direction?

• roots

• stem base

• shoot tip

• leaves

Plant bending toward light is controlled by:

• Carbon Dioxide

• Auxin (Plant Hormones)

• Xylem

• Chlorophyll

Roots growing downward is an example of:

• negative phototropism

• positive thigmotropism

• positive gravitropism

• negative gravitropism
