Answer 5

Ripened ovary and other structures of an angiosperm enclosing one or more seeds

Question 6

germination

Answer 6

sprouting seeds

Question 7

disperse

Answer 7

To transport or move

Question 8

Why have plants evolved specialized structures for reproduction?

Answer 8

successful reproduction

Question 9

what are the different stages

Answer 9

1. Sporophyte
2. Gametophyte

Question 10

In mosses and ferns, what does the sporophyte do?

Answer 10

The sporophyte releases spores that grow into male and female gametophytes.

Question 11

gametophyte

Answer 11

During the gametophyte stage, male and female gametophytes produce sex cells that will eventually be involved in the process of fertilization

Question 12

sporophyte

Answer 12

a plant produces the spores that will eventually develop into gametophytes

Question 13

In mosses and ferns, what does the gametophyte do?

Answer 13

Gametophytes produce sperm and egg cells that are needed for a zygote.

Question 14

what does the zygote form into

Answer 14

The zygote forms into a new sporophyte.

Question 15

repeating cycle name

Answer 15

Life Cycle

Question 16

What are the two types of vascular plants (that produce seeds)?

Answer 16

1. gymnosperms
2. angiosperms

Question 17

gymnosperm

Answer 17

In gymnosperms, gametophytes develop inside cones, withitn a larger sporophyte

Question 18

angiosperms

Answer 18

(gametophytes) they develop inside flowers, within a larger sporophyte

Question 19

Where is the gametophyte stage?

Answer 19

within a larger sporophyte

Question 20

what is the gametophyte and sporophyte in a tulip?

Answer 20

tulip= sporophyte
pollen/ovule=gametophyte

Question 21

What are the structures where the gametophyte forms?

Answer 21

1. Cones
2. Flowers

Question 22

What is the male gametophyte?

Answer 22

Pollen

Question 23

What develops into a sporophyte?

Answer 23

a zygote/seed

Question 24

What must happen before fertilization?

Answer 24

Pollination

Question 25

Asexual reproduction: Give an example of this in plants from a previous lesson

Answer 25

spider plant

Question 26

Why is apple tree grafting used?

Answer 26

To ensure that desired characteristics from the original tree are maintained in future trees

Question 27

What type of reproduction is grafting?

Answer 27

asexual

Question 28

What is an example of a gymnosperm?

Answer 28

Trees such as pines, redwoods, firs, cedars, and hemlocks

Question 29

How do gymnosperms disperse pollen?

Answer 29

Wind

Question 30

Why are the seeds of gymnosperms “naked”?

Answer 30

unprotected seeds

Question 31

How are these seeds dispersed?

Answer 31

wind

Question 32

What are two important characteristics of angiosperms

Answer 32

They all produce flowers and fruits that contain seeds.

Question 33

What contains the reproductive structures of angiosperms?

Answer 33

flower

Question 34

What are the male reproductive parts of the flower?

Answer 34

1. stamen 2. Filament 3. Anther

Question 35

stamen

Answer 35

anther + filament

Question 36

Which male part produces the pollen?

Answer 36

Anther

Question 37

What are the female reproductive parts of the flower?

Answer 37

Pistil Stigma Style Ovary

Question 38

What is the function of petals?

Answer 38

Attract pollinators

Question 39

What is the function of sepals?

Answer 39

Protects the growing flowers

Question 40

After fertilization, what does the zygote become?

Answer 40

embryo

Question 41

From what does the fruit develop?

Answer 41

ovary

Question 42

How are seeds dispersed? Give several examples.

Answer 42

Animal Waste Wind Falling into water Attach to fur or clothing if it has barbs

Question 43

Why do plants disperse their seeds?

Answer 43

Seeds dispersed far from the parent plant have a better chance of surviving, less competition.
