Which organism is most closely related
evolutionarily to a strawberry bush?
1.
2.
3.
4.
Non-vascular plants
Vascular seedless plants
Gymnosperms
Algae
The purpose of alternation of
generations is to…
1. provide a safe place for the diploid
plant to grow.
2. provide nutrients for the growing
diploid plant.
3. provide a place for fertilization to
occur.
4. 1 and 2
5. All of the above.
In both bryophytes and ferns
the spores are…
1. haploid.
2. unable to travel
far from the plant.
3. fertilized eggs.
4. multicellular.
Classroom Catalyst
Seed Anatomy
Why is the seed a good
adaptation for life on land?
1. It allows the plant to have multiple
offspring.
2. It contains endosperm, which
provides nutrients for the growing
embryo.
3. The embryo is kept dry until it
comes in contact with water.
4. It requires a lot of energy to
produce.
Which structure(s) below allow for
dispersal of a plant’s progeny?
1.
2.
3.
4.
5.
Seeds
Spores
Leaves
Stem/trunk
1 and 2
Which answer below is not true
for gymnosperms?
1. Their life cycle displays alternation of
generations.
2. Seed dispersal occurs via the wind.
3. The male and female gametophytes
(cones) look the same.
4. They can be extremely long lived.
Which answer below is an example
of coevolution between two
species?
1. A flower gets pollinated through wind
dispersal.
2. Seeds get dispersed by sticking to passing
animals.
3. A flower develops into a fruit for animals
to eat.
4. Yucca moths can only enter yucca plant
flowers that provide a place for the moths
to lay their eggs.
What is an advantage of double
fertilization in angiosperms?
1. Production of endosperm
2. Larger seeds
3. Increase in energy used to
make the seed
4. 1 and 2
5. All of the above
How do animals help plants?
1. Animals eat plant leaves, stems, and
roots.
2. Animals can provide nitrogen.
3. Predation signals plants to produce
MeJa.
4. Plants produce alkaloids in response to
predation.
5. 1 and 2
How are fungi and plants similar?
1. Both are sessile.
2. Both use photosynthesis to produce
food.
3. Both use chitin for building cell
walls.
4. Both have a dikaryotic state in their
life cycle.
5. Both have a prominent multicellular
haploid state in their life cycle.
What is the benefit of the symbiotic
relationship (mycorrhyzae) for the fungus
and plant respectively?
1. sugars for the fungus; protection for
the plant
2. increased nutrient absorption for the
fungus; sugars for the plant
3. sugars for the fungus; increased
nutrient absorption for the plant
4. protection for the fungus; increased
nutrient absorption for the plant
