stored food (nourishes the embryo)

seed coat (protects the embryo)

30
Q

Why will you never get cherries from radish seeds?

A

God designed seeds to produce after their own kind.

31
Q

Why is the stored food inside the seed important?

A

It must nourish the embryo until it is able to make its own food.

32
Q

Why are seeds designed to travel away from the parent plant?

A

If they didn’t, the taller plants would take most of the sunlight, water, and minerals in that spot, and they would not grow into strong, healthy plants.

33
Q

List three things that carry seeds away from the parent plant.

A

Any of: wind, water, animals, people

34
Q

What is unique about the way in which each of the following plants scatters its seeds?

(a) tumbleweed
(b) jewelweed
(c) dandelion

A

(a) tumbleweed: as it rolls across the prairies, it scatters its seed
(b) jewelweed: when the seed capsules are slightly touched, they burst open, scattering the seeds
