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

34
Q

What is a cotyledon?

A

“seed leaf” that in some cases emerges form seed coat upon germination

35
Q

What is a monocot?

A

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
Q

What is a eudicot?

A

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
Q

What is connation?

A

petals fused in single whorl (ex. snapdragon has 5 petals but fused together)

38
Q

T/F Monocots have a fibrous root system.

A

True

39
Q

T/F Eudicots have a taproot system.

A

True

40
Q

What does hypogynous mean in flower terms?

A

sepals, petals, and stamens attached at base of ovary,ovary said to be superior

41
Q

What does perigynous mean in flower terms?

A

sepals, petals, and stamens, are borne on remove teacup-like structure and ovary in middle (ex. cherry flower)

42
Q

What does epigynous mean in flower terms?

A

sepals, petals, and stamens emerge at (or near) top of ovary, ovary said to be inferior

43
Q

What kind of symmetry do flowers have when they can be divided along any axis to achieve 2 equal halves?

A

radially symmetric

44
Q

What are synonyms of radial symmetry?

A

actinomorphic and regular

45
Q

What kinds of symmetry do flower have when they can be divided only one axis to produce 2 equal halves?

A

bilaterally symmetric

46
Q

What are synonyms of bilateral symmetry?

A

zygomorphic and irregular

47
Q

What is adnation?

A

unlike flower parts fused, 2 whorls fused

48
Q

What is a perfect flower?

A

self-fertilize, have both stamens and carpels

49
Q

What is an imperfect flower?

A

has only stamens or carpels

50
Q

What 2 types of flowers are in an inflorescence?

A

disk and ray flowers

51
Q

What are disk flowers?

A

radially symmetric and bisexual

52
Q

What are ray flowers?

A

five fused petals that look like one petal, zygomorphic and often female

53
Q

Do ray or disk flowers have sepals?

A

no

54
Q

What does the microsporangium produce?

A

microspores

55
Q

What do microspores develop into?

A

male gametophytes (pollen grains that contain sperm)

56
Q

What does the megasporangium produce

A

megaspores

57
Q

What do the megaspores develop into?

A

female gametophyte (embryo sac that contains an egg)

58
Q

What is a fruit?

A

mature ovary

59
Q

What is a seed?

A

mature ovule

60
Q

What does a seed consist of?

A

surrounded by seed coat, contiane embryo and food

61
Q

What is the function the seed?

A

reproduction aka dispersal of seed not nutrition

62
Q

What is the wall of the fruit called?

A

pericarp

63
Q

What is a fleshy fruit?

A

attractive to animals, color and/or smell
