Produces one type of spore

Question 21

Integument

Answer 21

Layer of sporophyte tissue that contributes to the structure of an ovule of a seed plant

Question 22

Ovule

Answer 22

A structure that develops within the ovary of a seed plant and contains the female gametophyte

Question 23

Pollen

Answer 23

A fine powdery substance, typically yellow, consisting of microscopic grains discharged from the male part of a flower or from a male cone. Each grain contains a male gamete that can fertilize the female ovule, to which pollen is transported by the wind, insects, or other animals

Question 24

Pollination

Answer 24

The transfer of pollen to the part of a seed plant containing the ovules, a process required for fertilization

Question 25

Pollen Tube

Answer 25

A tube that forms after germination of the pollen grain and that functions in the delivery of sperm to the ovule

Question 26

Fertilization

Answer 26

The union of haploid gametes to produce a diploid zygote

Question 27

Seed

Answer 27

An adaptation of some terrestrial plants consisting of an embryo packaged along with a store of food within a protective coat

Question 28

Seed Coat

Answer 28

A tough outer covering of a seed, formed from the outer coat of an ovule. In a flowering plant, the seed coat encloses and protects the embryo and endosperm

Question 29

Dormant

Answer 29

Alive but not actively growing

Question 30

Germination

Answer 30

The process by which a plant grows from a seed

Question 31

Sporophyll

Answer 31

A modified leaf that bears sporangia and hence is specialized for reproduction

Question 32

Cone

Answer 32

Mass of scales or bracts, usually ovate in shape, containing the reproductive organs of certain nonflowering plants.

Question 33

Pollen Cone

Answer 33

Are generally much smaller than ovulate cones; they contain many sporangia, each of which makes numerous haploid spores by meiosis.

Question 34

Ovulate Cone

Answer 34

Female cone contains ovules which, when fertilized by pollen, become seeds Flower In an Angiosperm, a specialized shoot with up to four sets of modified leaves, bearing structures that function in sexual reproduction

Question 35

Sepal

Answer 35

A modified leaf in angiosperms that helps enclose and protect a flower bud before it opens

Question 36

Petal

Answer 36

A modified leaf of a flowering plant. Petals are the often colorful parts of a flower that advertise it to insects and other pollinators

Question 37

Stamen

Answer 37

The pollen producing reproductive organ of a flower consisting of an anther and a filament

Question 38

Anther

Answer 38

In an angiosperm, the terminal pollen sac of a stamen, where pollen grains containing sperm-producing male gametophytes form

Question 39

FIlament

Answer 39

In an angiosperm, the stalk portion of the stamen, the pollen producing reproductive organ of a flower

Question 40

Carpel

Answer 40

The ovule-producing reproductive organ of a flower, consisting of the stigma, style and ovary

Answer 41

The sticky part of a flowers carpel which receives pollen grain

Question 42

Style

Answer 42

A long, slender stalk that connects the stigma and the ovary
