Which of the following is not a plant adaptation for
life on land?
1. Roots, which stabilize and absorb water and
nutrients from soil
2. A waxy cuticle, which prevents water loss
3. Colonial living, which maximizes use of resources
while expending less energy
4. Stomata, which allow for gas exchange
5. Vessels that conduct water and sugars

Why is water needed for bryophyte reproduction?
1. Both the sperm and the egg develop in spores,
which must swim through water to undergo
fertilization.
2. The sperm must swim to the egg.
3. Without water, the sperm will fertilize the egg, but the
embryo will not develop.
4. Without water, the embryo will remain haploid
instead of diploid.

What is one of the main differences between club
moss and moss?
1. Club moss has vascular tissue.
2. Moss has leaves; club moss does not.
3. To conduct water and nutrients, club moss has
rhizoids rather than vessels.
4. Moss has sperm and egg within the same spore;
club moss has them in different spores.

Which of the following is not an adaptation that
enables evergreen trees to live in a cold, dry
ecosystem?
1. To protect the embryos from the cold, they develop
in the roots.
2. The trees grow continuously and undergo
photosynthesis year-round.
3. The trees have a waxy waterproof coating that
minimizes water loss.
4. The sap contains antifreeze that helps transport
fluids even in freezing temperatures.

In angiosperms, how does the sperm reach the egg?
1. The sperm uses flagella to swim to the egg.
2. The sperm and egg are produced inside the seed
and grow into an adult form.
3. The pollen forms a tube in the stigma, through which
the sperm travels to meet the egg.
4. The sperm fertilizes the egg outside the plant body.

Elephants contribute to their ecosystems by helping
plants grow in new areas. Why is it important that
the plant seeds elephants eat be enclosed in hard
coverings?
1.
2.
3.
4.
So that the seeds will not break when the elephants step on
them.
To deter the elephants from eating all of them.
To allow the seeds to begin to propagate in any environment.
To allow the seeds to survive while passing though the
elephant’s digestive system.
