Flashcards in chapter23C_Angiosperms Deck (35)
1

angiosperms distinguishing characteristic

flowering plants

2

most successful plant group

angiosperms

3

why are angiosperms so successful

number of seeds produced and speed of reproduction through pollinators

4

Peduncle

flower stem

5

Receptacle

flower foundation, inside peduncle

6

Calyx

sepals together, protects bud, supports petals

7

Corolla

petals collectively together

8

Coralla uses

attracts insects through emitting odor

9

male reproductive part of angiosperms

stamen

10

Filament role male Angiosperm

supports anther

11

Anter role male Angiosperm

where pollen is produced

12

Angiosperm female reproductive structure

carpel

13

Stigma role female angiosperm

nectar secretion, catches than activates pollen with enzymes from nectar

14

Style role female Angiosperm

supports stigma, opens upon ova maturation

15

Ovary role female Angiosperm

ova location, ova turns to seed and ovary turns to fruit

16

most fruits, vegetables, and trees are _dicot

eudicot

17

grasses and grains are _cot

monocot

18

Where do Eudicot and Monocots differ

seeds, stems, Roots, flowers, leaves

19

number of Eudicot flower petals

groups of 4 or 5

20

number of Monocot flower petals

groups of 3

21

vascual bundle

xylem and phloem

22

leaf differences between Eudicot vs Monocot

branching vs parallel veins

23

stem differences between Eudicot vs Monocot

vascular bundle (xylem/phloem) circular aroud stem, vascular bundle randomly across stem

24

root differences between Eudicot vs Monocot

vascular bundles located in the center of tap root, vascular bundles circular in fibrous root

25

seed germination differences Eudicot vs Monocot

2 cotyledons vs 1 cotyledon

26

Phylum Anthophyta common term

Flowering Plants

27

Where does pollen leave from on the flower

anther

28

Where does pollen enter on the flower

stigma

29

When does fertilization begin?

nectar enzymes on the stigma induce germination on the pollen

30

After pollen is induced to germinate, what happens next?

pollen tube having 2 sperm nuclei grow through style toward ovary

31

what do 2 sperm form upon fertilization completion?

one sperm fuses with egg nucleus to create diploid zygote, other sperm fuses with 2 egg nuclei to create triploid endosperm cell

32

what do the endosperm form

cotyledons

33

Eudicot seeds are divided in half between the _

cotyledons

34

in an apple, fertilized eggs become the _, and the fruit comes from the _

seeds, ovary

35

what is the bee orchid flower labellum

flower structure that imitates female bee instead of providing nectar for pollination
