Q

What general advantages do angiosperms possess that have allowed them to become dominant over gymnosperms?

A

more efficient vascular systems than gymnosperms, shorter germination times than gymnosperms, more rapid natural selection, pollination systems more efficient, make use of pollinators to move pollen, cross-pollination

25
What is the supporting stalk?

26
What is the fourth whorl?
carpels
27
What are the carpels?
female parts, evolved from leaves
28
What are the carpels together called?
gynoecium
29
What are the 3 parts of a carpel?
stigma-receptive surface for pollen, style-pollen tube grows carrying sperm, and ovary, contains one to hundreds of ovules
30
What will a fertilized ovule become?
a seed
31
What is a complete flower as opposed to an incomplete flower?
A complete flower has all 4 whorls present and an incomplete flower has one or more whorls missing.
32
When several flowers group together, what is it called?
inflorescence
33
What are the 2 categories of angiosperms?
monocots and eudicots
34
What is a cotyledon?
"seed leaf" that in some cases emerges form seed coat upon germination
35
What is a monocot?
flower parts in multiples of 3's, embryo has one cotyledon (thin and often used to absorb food (endosperm)), leaves are parallel-veined, do not have true vascular cambium-consists of cells that produce secondary growth and serve to thicken plant
36
What is a eudicot?
almost all angiosperms, flower parts in multiples of 4's and 5's, embryo has 2 cotyledons, leaves are net-veined, some have vascular cambium, cambium produces phloem to the outside and xylem to inside and phloem becomes bark, accumulating xylem is wood
37
What is connation?
petals fused in single whorl (ex. snapdragon has 5 petals but fused together)
38
T/F Monocots have a fibrous root system.
True
39
T/F Eudicots have a taproot system.
True
40
What does hypogynous mean in flower terms?
sepals, petals, and stamens attached at base of ovary,ovary said to be superior
41
What does perigynous mean in flower terms?
sepals, petals, and stamens, are borne on remove teacup-like structure and ovary in middle (ex. cherry flower)
42
What does epigynous mean in flower terms?
sepals, petals, and stamens emerge at (or near) top of ovary, ovary said to be inferior
43
What kind of symmetry do flowers have when they can be divided along any axis to achieve 2 equal halves?
radially symmetric
44
What are synonyms of radial symmetry?
actinomorphic and regular
45
What kinds of symmetry do flower have when they can be divided only one axis to produce 2 equal halves?
bilaterally symmetric
46
What are synonyms of bilateral symmetry?
zygomorphic and irregular
47
What is adnation?
unlike flower parts fused, 2 whorls fused
48
What is a perfect flower?
self-fertilize, have both stamens and carpels
49
What is an imperfect flower?
has only stamens or carpels
50
What 2 types of flowers are in an inflorescence?
disk and ray flowers
51
What are disk flowers?
radially symmetric and bisexual
52
What are ray flowers?
five fused petals that look like one petal, zygomorphic and often female
53
Do ray or disk flowers have sepals?
no
54
What does the microsporangium produce?
microspores
55
What do microspores develop into?
male gametophytes (pollen grains that contain sperm)
56
What does the megasporangium produce
megaspores
57
What do the megaspores develop into?
female gametophyte (embryo sac that contains an egg)
58
What is a fruit?
mature ovary
59
What is a seed?
mature ovule
60
What does a seed consist of?
surrounded by seed coat, contiane embryo and food
61
What is the function the seed?
reproduction aka dispersal of seed not nutrition
62
What is the wall of the fruit called?
pericarp
63
What is a fleshy fruit?
attractive to animals, color and/or smell
64
What is a simple berry fruit?
tomato
65
What is a simple hesperidium?
orange and lemon
66
What is a simple pepo?
cucumber, squash
67
What a is a simple pome?
apple
68
What is a simple drupe?
plum
69
What is the inner layer of the pericarp called?
endocarp
70
What is the middle layer of the pericarp called?
mesocarp
71
What is the outer layer of the pericarp called?
exocarp
72
What is a complex fruit?
developed from one or more ovary
73
What is an aggregate fruit?
raspberry
74
What is a multiple fruit?
pineapple
75
