Chapter 29

Question 1

anther

Answer 1

part of the stamen that produces pollen grains

Question 2

calyx

Answer 2

a flower’s outer, protective whorl of sepals

Question 3

carpel

Answer 3

floral reproductive organ that produces the female gametophyte; consists of an ovary, stigma, and usually a style

Question 4

Corolla

Answer 4

a flower’s whorl of petals; forms within sepals and encloses reproductive organs

Question 5

flower

Answer 5

specialized reproductive structure of an angiosperm

Question 6

ovary

Answer 6

in flowering plants, the enlarged base of a carpel, inside which one or more ovules form

Question 7

ovule

Answer 7

Of a seed plant, the part of the carpel where the female gametophyte forms

Question 8

petal

Answer 8

Unit of a flowers Corolla; often showy and conspicuous

Question 9

pollen grain

Answer 9

Immature male gametophyte of a seed plant

Question 10

pollination

Answer 10

The arrival of pollen on a pollen receiving reproductive part of a seed plant

Question 11

Pollination vector

Answer 11

Animal or environmental agent that moves pollen grains from one Plant to another

Question 12

Pollinator

Answer 12

An animal pollination vector

Question 13

Sepal

Answer 13

Unit of a flower’s calyx; typically photo synthetic and inconspicuous

Question 14

Stamen

Answer 14

Floral reproductive organ that consists of an anther and, in most species, a filament

Question 15

Stigma

Answer 15

Upper part of a carpel; adapted to receive pollen

Question 16

Nectar

Answer 16

Sweet fluid exuded by some flowers; rewards pollinators

Question 17

dormancy

Answer 17

Period of temporally suspended metabolism

Question 18

Double fertilization

Answer 18

Fertilization as it occurs in flowering plants. Two cells are fertilized: one sperm cell fuses with the egg to form the zygote; the second sperm cell fuses with the central cell to form a triploid (3N) cell that gives rise to endosperm

Question 19

Endosperm

Answer 19

Nutritive tissue in the seeds of flowering plants

Question 20

Germinate

Answer 20

To resume metabolic activity after dormancy

Question 21

Megaspore

Answer 21

Of seed plants, haploid spores that forms in an oval and gives rise to egg-producing gametophyte

Question 22

Microspore

Answer 22

Of seed plants, haploid spores that gives rise to a pollen grain

Question 23

Seed

Answer 23

Mature oval of an angiosperm. Consist of an embryo sporophyte, nutritive tissue, and a protective seed coat

Question 24

Fruit

Answer 24

Mature ovary of a flowering plant, often with accessory parts; encloses a seed or seeds

Question 25

coleoptile

Answer 25

In monocots, a rigid sheath that protects the plumule (embryonic shoot)

Question 26

Tissue culture propagation

Answer 26

Laboratory method in which embryonic plants are grown from individual meristem cells

Question 27

Vegetative reproduction

Answer 27

Growth of new roots and shoots from extensions or fragments of a parent plant; a form of asexual reproduction
