7. Sperm cells of a flowering plant are contained in ___.
a. Ovules b. Pollen grains
8. Saclike structures that produce pollen grains are ___.
a. Ovules b. Sepals c. Anthers d. Styles
9. What is the receptacle on a flowering plant?
a. The base of the flower where the ovary is stored
b. The tip of the stamen where the pollen is produced
10. Which of the following is TRUE about pollination and fertilization?
a. Pollination occurs when the pollen lands on the stigma of the female flower.
Sperm cells from the pollen grain move down into the ovary. Fertilization occurs
when one sperm cell fuses with the egg inside the ovule.
b. Fertilization occurs when the pollen lands on the stigma of the female flower.
Sperm cells from the pollen grain move down into the ovary. Pollination occurs
when one sperm cell fuses with the egg inside the ovule.
11. Which part of the flower develops into a fruit?
a. Petals b. Ovary c. Anther d. Stem
12. Eggs of a flowering plant are contained in ___.
a. Pollen grains b. Anthers c. Stamen
d. Ovules
13. What must happen for fertilization to occur in flowering plants?
a. The plant must be exposed to sunlight during pollination
b. The sperm cells in the pollen tube must be able to reach the eggs in the ovules.
c. The eggs in the ovules must be able to reach the top of the stigma where pollen
is trapped.
d. All of these
14. What are the parts of the pistil?
a. Stigma, Style, Ovary
b. Stamen, Ovary, Anther
c. Anther, Filament, Style
d. Filament, Stamen, Ovary
15. In what way are flowers adapted to help angiosperms reproduce?
a. The flowers store nutrients needed for the plant to grow.
b. The Flowers are an important source for human food.
c. The flowers help attract animals that are needed to deliver pollen.
