Worksheet: The Life Cycle of Flowering Plants: Flowers and Reproduction

In this worksheet, we will practice describing the role flowers play in the reproductive cycle of flowering plants and how they attract insects for pollination and fertilization.

Q5:

When the eggs in the ovary are fertilized by pollen, the ovary turns into a fruit.

What happens to the flower?

  • AThe petals grow.
  • BThe flower closes up.
  • CThe ovary becomes a seed.

Q6:

The flowers on a sycamore tree grow seeds with wings.

  • BBy wind
  • CBy explosion

Q7:

Complete the following sentence: Pollination is when is carried from one flower to another.

  • Aa seed
  • Bpollen
  • Ca bee
  • Dnectar

Q8:

Which of these sentences is not true about fruits?

  • AFruits are important for dispersing the seeds of the plant once the flower dies.
  • BFruits are made by the part of the flower that contains the seeds.
  • CFruits do not have seeds inside of them.
  • DFruits attract animals to eat and carry the seeds of the plant for dispersal.

Q9:

Which comes first in the life cycle of a plant, pollination or fertilization?

  • AFertilization
  • BPollination

Q10:

Fill in the blank: Fertilization is when pollen joins to make a seed.

  • Aa seed
  • Ban egg
  • Ca bee
  • Da fruit

Q11:

After an egg and pollen join together (fertilization), which part of the plant grows into a fruit?

Young sour apples-72 ppi
  • AThe roots
  • BThe stem
  • CThe ovary
  • DThe sepal

Q12:

Insects that help pollinate flowering plants are known as pollinators. They are attracted to the bright colors of the flowers. Butterflies are pollinators. Choose another pollinator from the list.

  • ASpiders
  • BSnails
  • CBees
  • DSnake

Q13:

How are plants that do not have brightly colored flowers pollinated?

  • ABy bees
  • BBy birds
  • CBy wind
  • DBy butterflies

Q14:

There are different ways that pollen can be carried from one plant to another.

Golden honeybee-72 ppi
  • AWind
  • BWater
  • CAnimal

Q15:

The diagram shows how flowering plants reproduce.

Which of these statements describes what happens during fertilization?

  • AThe pollen from one flower travels down the pistil of another flower to fertilize the egg.
  • BThe pollen from one flower travels down the anther of another flower to fertilize the egg.
  • CThe pollen from one flower travels down the stem of another flower to fertilize the egg.
  • DThe pollen from one flower travels down the stigma of another flower to fertilize the egg.
