Question
Chapter 9 Study Guide – Multiple Choice

Question 1

The xylem is made from ________.

1. elongated living cells

tubular living cells

dead, hollow cells

intercellular spaces between cells

Question 2

Which is not a characteristic of the gymnosperms?

1. Cones

Pollen

Seeds

Flowers

Question 3

All plant organs (such as leaves, roots, and stems) contain tissues from all three tissue systems.

True

False

Question 4

Assuming it doesn’t die unexpectedly, how often would you need to replant an annual plant?

1. Every two years

Every season

Never

Every year

Question 5

What is a major role that fungi play in ecosystems?

1. Photosynthesis

Synthesizing glucose from carbon dioxide and water

Fixing carbon from the atmosphere

Recycling nutrients from dead organisms back into the food chain

Question 6

What is the main purpose of flowers?

1. To attract attention in the landscape

To attract pollinators

To attract predators

To be pleasing to the human eye

Question 7

How does a plant get the carbon it needs to make glucose?

1. From fungus or bacteria

From the soil

From the air

From the water

Question 8

While mosses can cover a significant area of land, they are never more than a few centimeters tall. Why do they not grow tall?

1. They are annuals and simply don’t live long enough to get very tall.

They don’t get enough sunlight to grow tall.

Herbivores constantly eat them to the ground.

They have no vascular system, so they cannot transport water over long distances.

Question 9

Not all plants have seeds. What advantage do seeds provide a plant?

1. Plants with seeds are not dependent on water for reproduction.

Plants with seeds need not go through an alternation of generations.

Plants with seeds need not produce cones.

Plants with seeds need not produce gametes.

Question 10

Which is the most recent plant adaptation to have evolved?

1. Cones

Vascular system

Seeds

Flowers

Question 11

Ferns often have small bumps called sori arranged in rows on their undersides. What are these structures?

1. Parasites

Seed capsules

Spore capsules

Nodules containing symbiotic bacteria

Question 12

Which type of angiosperm typically has parallel leaf veins and a fibrous root system?

1. Conifer

Legume

Dicot

Monocot

Question 13

Which statement related to gymnosperm reproduction is true?

1. Spores produce pollen grains, which contain sperm.

Two sperm are required to fertilize the ovule.

Many gymnosperms rely on insects for pollination.

Gymnosperm reproduction is so inefficient that gymnosperms do not grow very tall or live for very long.

Question 14

If a fungicide was applied near a plant, how might it kill the plant?

1. By breaking down the chitin in the plant’s cell walls

By killing the insects that pollinate the plants

By killing the fungus associated with the plant’s roots

Fungicides kill fungi, not plants, so the plant would be fine.

Question 15

The xylem primarily transports ________, while the phloem primarily transports ________.

1. oxygen and carbon dioxide; sugars

water and minerals; sugars

water and minerals; oxygen

sugars; water and minerals

Question 16

Why are roots essential for terrestrial plants?

1. They allow plants to obtain sun energy.

They absorb water and minerals needed for growth.

They absorb carbon dioxide needed for photosynthesis.

None of the above; plants can function without roots.

Question 17

What are the charophytes?

1. An extinct group of protists that may have given rise to the fungi

Algae that live symbiotically with fungi

Closest living ancestors of the first plants

Smallest living plants

Question 18

The edible portion of the mushroom is the ________.

1. above-ground reproductive structure

mycelium

spore

hypha

Question 19

What are the two types of symbiotic relationships in plants?

1. Bacteria in root hairs, fungi in root nodules

Bacteria in mycorrhizae, fungi in root nodules

Bacteria in root nodules, fungi in root hairs

Bacteria in root nodules, fungi in mycorrhizae

Question 20

The tall ferns that we typically see in the tropics and temperate woodlands are the ________.

1. gametophytes

gametes

sporophytes

spores

Question 21

How do fungi reproduce sexually?

1. Fungi reproduce only by asexual reproduction

By the fusion of gametes from two different fungi

By the fusion of spores from two different fungi

By the fusion of hyphae from two different fungi

Question 22

Are all fungi prokaryotes?

1. No, they are neither prokaryotes nor eukaryotes.

Yes, all fungi are prokaryotes.

No, some are prokaryotes, some are eukaryotes.

No, they are all eukaryotes.

Question 23

Which of the following is a fungus?

1. Truffles

Yeast used to make bread

Mushrooms

All of the above are fungi

Question 24

Why must mosses live in moist environments?

1. Because they grow as a mat

Because they are pollinated by fish and aquatic insects

Because they depend on water to reproduce

Because they lack a waxy outer layer

Question 25
