Plants Test Review

What are the defense mechanisms that plants have to protect themselves

• Production of fruits

• Gravitropism

• Production of thorns or toxins

• Stomata closing

What effect does gravitropism have on plant growth?

• It causes plants to change color in the fall

• It causes roots to grow down, and shoots to grow up

• It causes plants to grow towards light

• It causes plants to grow around objects they are touching

What are ways that seeds are adapted to be dispersed? (Check all that apply)

• Stored in fruit

• Have wing like shapes

• Have barbs or hooks on them

• Produce toxins

What happens to the sugar produced by photosynthesis?

• It is lost through transpiration

• It becomes a reactant of photosynthesis

• It is released from the roots

• It is either used in respiration, or stored

What process helps water travel from the ground up to the leaves?

• Active transport

• Transpiration

• Pollination

• Cellular respiration

What is the purpose of root hairs?

What are the male reproductive organs of a flower?

• Stamen, anther, filament

• Stigma, style, ovary

• Style, petal, pollen

What is the process of flower fertilization?

• An ovule fertilizes pollen at the anther

• Pollen enters the filament and fertilizes a seed

• Pollen is stored in fruit and fertilizes a seed inside.

• Pollen enters through the stigma and fertilizes an ovule
