A

true

29
Q

a functional megaspore, which divides mitotically to produce the

A

embryo sac or megagametophyte

30
Q

having the corolla composed of united petals

A

gamopetalous

31
Q

one of the outer parts of a flower (collectively the perianth), The term is used when these parts cannot easily be classified as either sepals or petals.

A

tepal

32
Q

having many distinct or separate petals

A

polypetalous

33
Q

bundle of leaves or flowers growing crowded together

A

fascicle

34
Q

Flowers can vary from containing both male and female parts

A

perfect

35
Q

Flowers containing just one sex

A

imperfect

36
Q

Flowers having no sexual parts

A

sterile

37
Q

Female and male flowers are located on separate plants

A

dioecious

38
Q

Female and male flowers are located on the same plants

A

monoecious

39
Q

petals of the flower can either be free from each other

A

polypetalous

40
Q

petals of the flower can either be united forming a cup or tube with separate terminal lobes.

A

gamopetalous

41
Q

symmetry is based on a wheel plan

flower is divisible on more than one axis into two equal halves that are mirror images of each other

A

radial symmetry

actinomorphic symmetry

42
Q

distinctly divisible into right and left sides; that is, it is divisible into mirror images on only one axis.

A

bilateral symmetry

irregular or zygomorphic symmetry

43
Q

four types of irregular flowers

A

bilabiate, caesalpinaceous, orchidaceous and papilionaceous.

44
Q

A flower with superior ovary is such that the stamens, petals and sepals arise from a level below the base of the ovary

A

hypogynous flower

45
Q

that the flower has superior ovary but the bases of the stamens, petals and sepals develop as a floral cup around the pistil. Hypanthium

A

Perigynous flower

46
Q

the stalk of an individual flower within an inflorescence.

A

pedicel

47
Q

stalk of an inflorescence (containing one to many flowers)

A

peduncle

48
Q

part of the flower that turns into the pericarp

A

ovary wall

49
Q

part of the flower that turns into the seed

A

ovule

50
Q

part of the flower that turns into the seed coat

A

integument

51
Q

The main axis (also referred to as major stem) above the peduncle bearing the flowers or secondary branches

A

rachis

52
Q

a flower cluster with the separate flowers attached by short equal stalks at equal distances along a central stem. The flowers at the base of the central stem develop first.

A

raceme

53
Q

is a raceme, but the flowers develop directly from the stem and are not borne on pedicels

A

spike

54
Q
  • a compound raceme; an indeterminate inflorescence in which the flowers are borne on branches of the main axis or on further branches of these
A

panicle

55
Q

one in which the flower stalks arise at different levels on the main axis and reach about the same height and in which the outer flowers open first

A

corymb

56
Q

consists of a number of short flower stalks (called pedicels) that spread from a common point, somewhat like umbrella ribs.

A

umbel

57
Q

a short dense spike in which the flowers are borne directly on a broad, flat peduncle, giving the inflorescence the appearance of a single flower

A

head

58
Q

instead of individual flowers radiating out from a single point, there are instead inflorescence branches. At the ends of each branch are secondary umbels.

A

Compound umbel

59
Q

a flat-topped inflorescence in which the central flowers open first, followed by the peripheral flowers

A

compound cyme

60
Q

The main axis terminates in flower and it produces one lateral branch from the base, which also terminates in a flower. Each lateral and subsequent branch also produces one lateral branch with a terminal flower.

A

cyme

61
Q

typically surrounded by a leaf-like curved bract known as a spathe

A

spadix

62
Q

a form of pollination whereby pollen is distributed by wind

A

Anemophily

63
Q

a form of pollination whereby pollen is distributed by water

A

hydrophily

64
Q

a form of pollination whereby pollen is distributed by insects

A

entomophily

65
Q

a form of pollination whereby pollen is distributed by bats

A

chiropterophily

66
Q

a form of pollination whereby pollen is distributed by birds

A

ornithophily

67
Q

a type of cymose inflorescence
like a hollow-sphere (syconium) with a cavity inside, and it is formed by the fusion of the rachis of the three cymes in the vicinity of each other. These spherical receptacles are like a closed fleshy vessel having a tiny opening at the apex; it opens to the exterior with this opening.

A

Hypanthodium

68
Q

the basic unit of a grass flower, consisting of two glumes or outer bracts at the base and one or more florets above.

A

spikelet

69
Q

specialised pseudanthia (“false flowers”) forming the inflorescence of plants\
the brackets fuse to form a cup-shaped structure

A

cyathium

70
Q

a cuplike or tubular enlargement of the receptacle of a flower, loosely surrounding the gynoecium or united with it. In epigynous and perigynous, not hypogynous

A

hypanthium
