Biology B10 Quiz Angiosperms

Angiosperms, or flowering seed plants, form seeds in ____________

• ovaries

• stamens

• flowers

• pistils

Which of these are main parts of a flower?

• pistils

• stamens

• sepals

• petals

• fruit

Which of these are true?

• The stamen is the male reproductive structure of a flower.

• The pistil is the female reproductive structure of a flower.

• Sepals attract pollinators to the flower.

• Anthers protect the developing flower while it is still a bud.

• A flower includes both male and female reproductive structures.

Why do angiosperms "hide" their nectar?

• To attract only very specific pollinators, which would be more likely to visit only flowers of the same species.

• To stop pollinators from taking too much nectar, which they need for growth and development of fruits.

• To trap pollinators inside of the flower. The increases the chances of pollination.

• none of these

Humans started domesticating grasses such as wheat about __________ years ago.

• 1000

• 10,000

• 100,000

• 1 million

Humans chose grasses for domestication because hey have many large, edible seeds that contain a lot of nutritious stored food. They are also relatively easy to harvest.

• true

• false

Flowering plants have co-evolved with some animals to become better suited for their roles in the symbiotic relationship.

• true

• false

Which of these are major groups of angiosperms?

• monocots

• conifers

• eudicots

• gnetae

• magnolids

This the part of the stamen that contains pollen sacs where meiosis occurs and pollen grains form.

• pistils

• sepals

• anthers

• petals

While visiting a flower, a pollinator picks up pollen from the pistils. When the pollinator visits the next flower, some of the pollen brushes off on the sepals. This allows cross-pollination, which increases genetic diversity.

• true

• false
