plant test review

Scientists can make mutations in plants by radiating their seeds. This could cause a plant not to produce flowers. Because of this lack of flowers, the plant would not be able to:

• carry out photosynthesis

• transport water

• reproduce sexually

• grow more than a few inches tall

After a flower on a cherry tree is fertilized, what part of the flower will develop into the fruit?

• stamen

• anther

• ovary

• ovule

In flowers, pollination will most likely occur when

• gravity causes pollen to fall from the stigma to the anthers

• insects transfer pollen from an anther to a stigma

• the wind transfers pollen from the pistil to the stamen

• many specialized cells are released from the ovary
