Front 1

he anthers of the flower produce ____ that form_____

Back 1

microspores--- male gametes (pollen)

Front 2

Ovules produce______
that form _______

Back 2

megaspores--- female gametophytes (embryo sac)

Front 3

After its released from the anther, pollen is carried to the

Back 3

sticky stigma of carpel

Front 4

The pollen gram _____ from the stigma towards the ovary

Back 4

germinates (begins growing)

Front 5

a pore in the integuments of the ovule,

Back 5

microphyte

Front 6

When the pollen tube reaches the microphyte,

Back 6

it discharges two sperm cells into the female gametophyte.

Front 7

            
double
fertilization-

Back 7

one sperm unites within the eggs to form a diploid zygote and
the other fuses with two nuclei in the large center cell of the female
gametophytes

Front 8

are
specialized shoots bearing the reproductive organs of the angiosperm sporophyte

ovary

Front 10

male bar to the flower and its organisms

Back 10

stamen
anther
filament

Front 11

Male gametophytes develop within the

Back 11

anthers

Front 12

female gametophytes develop within the

Back 12

ovaries

Front 13

brings male and female gametes together

Back 13

Pollination

Front 14

unisex plants

Back 14

Dioecious

Front 15

Plants mechanisms that prevent self-fertilization

Back 15

Diocious plants
cannot self fertilize they are unisex
In some species
stamens and carpals mature at different times              
Or they may be
arranged so that it is unlikely that an animal pollination could transfer
pollen from the anther to the sigma of the same flower

Front 16

the ___ develops into a _____containing the embryo and supply nutrients

Back 16

The ovule
seed

Front 17

After double fertilization the ovule develops_______

Back 17

into a seed

Front 18

After double fertilization the ______ develops into a seed

Back 18

ovule

Front 19

After double fertilization the ______ develops into into a fruit enclosing the seeds

Back 19

ovary

Front 20

Ater double fertilization the ovary develops into

Back 20

into a fruit enclosing the seeds

Front 21

The ovary develops into a fruit adapted for

Back 21

seed dispersal

Front 22

he wall of the ovary becomes the ____ the
thicken wall of the fruit while other parts of the flower wither or shed

Back 22

pericarp,

Front 23

the
thicken wall of the fruit while other parts of the flower wither or shed

Back 23

pericarp,

Front 24

 In apples the
fleshy part of the fruit is derived mainly from the ______, while the
core of the apple fruit develops from_____

Back 24

swollen receptacle
the ovary

Front 25

Fruits are
classified into several types depending on their developmental orgin

Back 25

Simple fruits are
derived from a single ovary
Aggregated fruits
such as a blackberry results from a single flower with several carpals

Front 26

As a seed
matures, it dehydrates and enters a ________, condition of extremely low
metabolic rate and suspension of growth and development

Back 26

dormancy phase

Front 27

condition of extremely low
metabolic rate and suspension of growth and development

Back 27

dormancy phase of seedlings

Front 28

Some seeds
germinate as soon as they are in a suitable environment

Back 28

water

Front 29

Other remain
dormant until some specific environmental cue causes then to break dormancy

Back 29

These include
fire, flood, cold, digestion

Front 30

Germination of seeds depends on the uptake of water due to the

Back 30

lower water potential of the dry seed

Front 31

 The causes the
expanding seed to rupture

Back 31

its seed coat and trigger metabolic changes in the
embryo that enable it to resume growth

Front 32

many plants ___ themselves in asexual reproduction

Back 32

clone

Front 33

This occurs when
a part separates from the overall plant and eventually develops into a whole
plant

Back 33

meristem cloning

Front 34

Asexual
reproduction is an extension of the capacity of plants for growth

Back 34

indeterminate

Front 35

Meristematic
tissues with dividing undifferentiated cells can ____
indefinitely

Back 35

sustain or renew growth
inmortality

Front 36

__________-cells
throughout the plant can divide and differentiate into various types of
specialized cells

Back 36

Front 37

These produce seeds without their flowers being
fertilized
