Which is a way animals can help spread seeds?

• Eating fruit.
• Eating leaves.
• Digging up plants.
• Eating stems.

Which part of an angiosperm is responsible for reproduction?

• stem

• roots

• flower

• leaf

Which is NOT a way that pollen can move from one flower to another?

• birds
• insects
• rain
• wind

Which of the following sentences describes the ways plants spread their seeds? Choose the two that apply.

• Bees, attracted by brightly colored flowers, pick up and move seeds to new locations.

• Animals, attracted by scent, eat and then disperse seeds in new locations through their droppings.

• Seeds are carried away from the parent plant by wind or water.

• Seeds are dispersed during pollination.

Grafting is when part of a plant’s stem is cut and then attached to another plant. Apple farmers often use grafting to ensure that new plants will have the desired characteristics of the original apple tree. What kind of reproduction is this?

What type of plant life cycle is illustrated in this image?

• gymnosperm

• angiosperm

• non vascular plant

• fern

Gymnosperms are plants that

• produce seeds inside of cones.

• produce flowers and fruit.

• are pollinated by animals.

• produce spores rather than seeds.

A plant typically wants to disperse its seeds far away from the parent plant because

• the soil and growing conditions will be better elsewhere.

• the offspring will have better genetic diversity.

• there will be less competition for resources, thus increasing their survival rate.

• there will be more competition for resources, which ensure that only the strong survive.
