Seed Germination

Seed germination is initiated by

imbibition

Imbibition causes the seed to

expand and rupture its coat

Enzymes digest stored food in

endosperm and/or cotyledons

Nutrients are transferred to the

growing embryo

media

Germination in Dicots

The first organ to emerge is

the radicle

Hook forms in the hypocotyl,

and growth pushes the hook
above ground

Hypocotyl straightens, the

cotyledons separate, and the
epicotyl spreads its first true
leaves

97

Germination in

Monocots

Shoot tip grows

through the coleoptile
(sheath) once it has
pushed through the
surface of the soil

The cotyledon remains

belowground

Multiple Choice

What are the stages of embryo development in angiosperms?

1

Zygote, endosperm, seed coat

2

Embryo sac, endosperm, seedling

3

Fertilization, embryogenesis, germination

4

Gametophyte, sporophyte, embryo

101

Multiple Choice

Which of the following best describes endosperm development in angiosperms?

1

Formation of the protective seed coat

2

Maturation of the embryo into a seedling

3

Division and growth of the triploid cell to provide nourishment

4

Fusion of male and female gametophytes

102

Multiple Choice

What is the primary importance of seed dormancy in plant life cycles?

1

Prevents germination in unfavorable conditions

2

Promotes rapid growth of seedlings

3

Ensures cross-pollination

4

Increases seed production

103

Multiple Choice

How does seed germination differ between eudicots and monocots?

1

Eudicots have two seed leaves, while monocots have one

2

Monocots have larger seeds than eudicots

3

Eudicots undergo double fertilization, while monocots do not

4

Monocots have longer periods of seed dormancy

104

Multiple Choice

What is the function of cotyledons during seed germination in eudicots and monocots?

1

They protect the embryo from pathogens

2

They store nutrients for the developing seedling

3

They facilitate water absorption from the soil

4

They produce pollen for pollination
