(Structures in Land Plants that evolved to deal with it on dry
land)

1. Multicelluar algae floated and drifted freely in the
water

a. Cuticle

b. pollen and seeds

c. Lignin

2. Alage cells absored nutrients directlly from
water

a.Vascular Tissue

b. Pollen and seeds

c. Cutcle

3. Both single-celled and multicellur algae released
free-floating gametes into water

a. Lignin and cuticle

b. Pollen and seeds

c. Xylem abd phloem

4. Alage Cells were immersed in water, which prevents
dehydration

a. Phloem

b. Cuticle

c. Pollen and seeds

5. Bryophytes are usually found in areas that are very
wet or damp at least part of the year. Which of the following
statements describes characteristics of bryophytes that make them
dependent on water? Which all apply?

a. They have swimming sperm that need water so they can swim to
fertilize the eggs of other nearby plants.

b. They have dominant gametophyte phase.

c. Some species are able to reproduce asexually through
fragmentation.

6. Which part of a bryophyte plant produces
spores?

a. Sporophyte

b. Gametophyte

7. The seedless vasuclar seeds plants not only include
well-known plants such as ferns but also groups of plants called
horsetails and club mosses. These plants originally arose after the
bryophytes. Which of the following statements describes why
seedless vascular plants are better adapted t dry land than the
bryophytes?

a. Seedless vasuclar plants have larger leaves, or fronds, that
are more effective in absorbing nutrients from the enviroment.

b. Seedless vascular plants have spores that can distribute on
the wind.

c. Seedless vascular plants have vascular tissue and roots to
effectively absorb and distribute water and nutrients throughout
the plant.

8. However, seedless vasuclar plants are still heavily
dependent on water for reasons other than keeping hydrated. Which
of the following statements correctly explains how seedless
vascular plants are still dependent on water?

a. Seedless vascular plants, require water, instead of wind, to
spread their spores.

b. Seedless vascular plants still have swimming sperm that need
water to reach the eggs for fertilization.

c. Seedless vascular plants require water to germinate the spore
to grow into a rhizome

9. In seedless vascular plants, the sporophyte grows
from the

a. sori on the underside of the gametophyte

b. zygote contained on the gametophyte

c. spores once they take root in the soil

10. Most species of horsetails and club mosses died off
by the end of which period?

a. Tertiary

b. Permian

c. Jurassic

11. Which of these is an advantage that seeds have over
spores?

a. Seeds can be spread on the wind or by animals, while spores
have to swim through water

b. Seeds require less energy for the plant to produce than do
spores

c. Seeds contain a store nutrients to nourish the plant embryo
until it is able to grow

12. Gymnosperms were also the first plants to develop
pollen. Which of the following statements correctly describes one
of the advantages of pollen?

a. The development of pollen means that gymnosperms no longer
require sporophytes for reproduction

b. Pollen is created by the sperm of the plant

c. Pollen can spread on the wind to pollinate plants in distant
locations.

13. In gymnosperms, where are the male gametophytes
located?”

a. The gametophyte stage no longer exists in gymnosperms

b. They are the pollen grains

c. In the flowers.

14. Angiosperms are the most diverse group of plants in
existence today. Which of the following plants structures do
angiosperms possess that are not found in any earlier lineage of
plant?

a. Pollen

b.Flowers

c. Seeds

15. Most angiosperms incorporate the assistance of
animals in their reproductive cycle. This is a majro advancement
that gave them an advantage over other plant lineages and helped
them become the dominant type of plant on Earth today. Which of the
following steps in the reproduction of angiosperms do animals
assist with? Which all apply?

a. Meiosis

b. Pollination

c. Seed dispersal.

16. In angiosperms, which structure represents the male
reproductive organs of the plant?

a. Stamen

b. Sepal

c. Carpel
