Like all plants, bryophytes have an alternation of generations. What is the name of the multicellular haploid structure?

gametophyte

Bryophytes lack vascular tissue and lignin and therefore cannot

grow tall.

In alternation of generations, a diploid sporophyte goes through meiosis to form _____ spores.

haploid

In alternation of generations, a haploid gametophyte goes through mitosis to form a ____ gamete.

haploid

Ferns have advantage over bryophytes in that ferns

have a vascular system, which allow them to grow taller.

Where does fertilization occur in angiosperms?

in ovules

Like all plants, angiosperms have an alternation of generations. What structure is a gametophyte in the angiosperm life cycle?

pollen grain

Gymnosperms have an advantage over ferns in that gymnosperms

produce pollen and do not require water to reproduce

The parts of the plant that absorb water and minerals are the

roots

Select the feature that distinguishes a conifer from a true fern.

seeds

Select all of the following that are true about the fern gametophyte.

site of pollen production invisible to the naked eye

What must be present for fertilization to occur in bryophytes?

water

In the group of plants shown here, how do the male gametophytes released by the male cones reach the female gametophytes during pollination?

wind

The two types of vascular tissue in most plants are

xylem and phloem.

The parts of the plant that conduct water and dissolved minerals from the roots to the leaves are the

xylem.

The term "gymnosperm" means

"naked seed."

Match each structure or description with the correct stage in the general plant life cycle image. Some labels may be used more than once.

1. pollen grain, haploid 2. sperm cell, haploid, egg sell 3. this is produced when gametes unite, diploid 4. diploid, stem and leaves of a fern 5. microspore and megaspore, haploid

Evidence that green algae are the closest relatives to plants is that they both

All answers are correct.

Plants are

All of the answer choices are correct.

Categorize each label with the plant group it describes. Some labels may be used more than once.

Bryophytes- swimming sperm Seedless vascular plants- swimming sperm, vascular tissue Gymnosperms- vascular tissue, pollen, seeds Angiosperms- vascular tissue, pollen, seeds, flowers, fruit

Classify the following fern structures as either haploid or diploid.

Diploid- sporangium, root, frond, zygote Haploid- spre young gametophyte, sperm-producing structure, egg cell.

Match each terrestrial adaptation in plants to its correct description.

Leaves - Increase surface area for photosynthesis Stomata and cuticle- Minimize water loss from plants Vascular tissue- Nutrient and fluid transport Roots- Obtain minerals and water from environment Flowers- Reproductive structure in angiosperms Pollen grains- Deliver sperm cells to female flower parts

You are asked to place descriptive labels on a plant model which all students in an introductory laboratory will examine. ________ would receive a label saying "transports sugars around the plant."

Phloem

Classify each of the following as either a similarity or a difference between plants and green algae.

Similarity- common ancestor 475 million years ago, chloroplast pigments, photosynthesis, eukaryotic cells. Differences- presence of adaptations to land, method of gamete dispersal

The bright colors and sweet smell of flowers attract animals that help the plant to

Spread Pollen

Match each type of plant to its correct description.

True Moss- These nonvascular plants can often survive on bare rock. True Fern- This vascular plant produces swimming sperm. Angiosperm- This vascular plant produces flowers that, when pollinated, develop into fruits. Conifer- This vascular plant produces seeds but lacks flowers and fruits.

Select the characteristic that distinguishes a fern from a liverwort.

Vascular Tissue

Classify each of the following as belonging to, or characteristic of, a vascular or nonvascular plant.

Vascular- angiosperms, fern, gymnosperms, phloem, cell walls with lignin. Nonvascular- moss, hornworts

Which of these plant groups has a haploid gametophyte generation? Select all that apply.

all plants

What part of plant cells contains chlorophyll a and carries out photosynthesis?

chloroplast

The ______ provide(s) a waxy coating that minimizes water loss from leaves of the plant.

cuticle

In plants that have two haploid gametes fuse during fertilization, the zygote is

diploid.

The structure of the angiosperm that supplies nutrients to the germinating seedling is the

endosperm.

The cones of gymnosperms play the same role as ______ in angiosperms.

flowers

Fill in the blanks in the following sentences. Hint: use the terminology from figure 16.5.After pollinators bring ___________ (pollen grains) to a flower, sperm and egg meet, forming a ___________. This cell develops into a mature ___________, which produces ___________ by meiosis.

male gametophytes; zygote; sporophyte; spores

The two groups of angiosperms are

monocots and eudicots

In flowering plants, the gametophyte is ______ the sporophyte.

much smaller than

What term describes the process by which plants produce food and oxygen using the sun's energy?

photosynthesis

In plants,

the diploid zygote develops into the sporophyte.

A cotyledon is

the first leaf structure to arise in the embryo of an angiosperm.

In the plant life cycle, daughter cells produced by mitosis might be either haploid or diploid.
