Stamen

is the pollen producing reproductive organ of a flower,

comprised of anther and filament.

TERM 2

anther

DEFINITION 2

contains the pollen

TERM 3

carpel

DEFINITION 3

female reproductive organ, contains stigma, style and ovary

TERM 4

filament

DEFINITION 4

thin structure that holds the anther

TERM 5

stigma

DEFINITION 5

receptive tip of a carpel, it receives pollen

ovary

holds ovules

TERM 7

petals

DEFINITION 7

surround reproductive parts of flowers, meant to attract

pollinators

TERM 8

sepals

DEFINITION 8

part of the flower of angiosperms, function as protection,

enclose flower

TERM 9

receptacle

DEFINITION 9

an enlarged area at the apex of a stem that bears the organs

of a flower or the florets of a flower head

TERM 10

compete flowers

DEFINITION 10

contain all four floral organs; petals stamen, sepal and carpel

megaspores

in ovules, megaspores are produced by meiosis and develop

into the embryo sac, the female gametophyte

TERM 17

fruit

DEFINITION 17

-develops from an ovary-protects and helps disperse seeds-is

classified as dry or fleshy, and by what flower parts comprise

of it

TERM 18

double

fertilization

DEFINITION 18

two sperm enter the embryo sacthe second combines with

two polar nuclei -> 3n endosperm

TERM 19

seed and endosperm development

DEFINITION 19

-in most monocots and some euditcots endosperm stores

nutrients.-in other eudicots, the endosperm reserves are

exported to the cotyledons

TERM 20

major steps to seed germination

DEFINITION 20

Step 1-Water imbibation results in rupture of seed coat,

optimum temperatures are required

Step 2-The imbibition of the seed coat results in

emergence of the radicle and the plumule, the

cotyledons get unfolded.

Step 3- final step in the germination of the seed.

cotyledons are expanded which are the true leaves.
