1 Ch 30 – Plant Reproduction
Vocabulary Review Ch 30 – Plant Reproduction

2 A reproductive structure that produces male sex cells in flowerless and seedless plants

3 A female reproductive structure of small, nonvascular plants that produces a single egg and in which fertilization and development take place Archegonium

4 The production of only one kind of spore

5 A cluster of spores or sporangia

6 The smaller of the two types of spores produced by most plants that develops into the male gametophyte Microspore

7 The larger of the two types of spores produced by heterosporous plants; develops into a female gametophyte Megaspore

8 The production of two or more kinds of asexual spores

9 The outer, protective covering of a body, a body part, an ovule, or a sporangium

10 The small opening in the wall of an ovule through which a pollen tube enters the ovule

11 A structure in the ovary of a seed plant that contains an embryo sac and that develops into a seed after fertilization; in gymnosperms the ovule is found in the carpel and is structurally simple and naked Ovule

12 The structure that contains the male gametophyte of seed plants
Pollen grain

13 The transfer of pollen from the male reproductive structures (the anthers) to the tip of a female reproductive structure (the pistil) of a flower in angiosperms or to the ovule in gymnosperms Pollination

14 A tubular structure that grows from a pollen grain, enters the embryo sac, and allows the male reproductive cells to move to the ovule Pollen tube

15 The enlarged tip of a flower stalk to which the flower is attached

16 In a flower, one of the outermost rings of modified leaves that protect the flower bud

17 One of the usually brightly colored, leaf-shaped parts that make up one of the rings of a flower

18 The male reproductive structure of a flower that produces pollen and consists of an anther at the tip of a filament Stamen

19 In flowering plants, the tip of a stamen, which contains the pollen sacs where grains form

20 In flowers, the part of a stamen that supports the anther

21 The structure where the ovule is in flowering plants

22 The female reproductive part of a flower that produces seeds and consists of an ovary, style, and stigma, made of one or more fused carpels Pistil

23 In the female reproductive system of animals, an organ that produces eggs; in flowering plants, the lower part of a pistil that produces eggs in ovules Ovary

24 In plants, the slender, upper part of the pistil

25 The expanded apex of a pistil, supported by the style; the part of the pistil that receives the pollen Stigma

26 In plants, the female gametophyte that develops from a megaspore; contains the ovum that fuses with a sperm nucleus during fertilization to form an embryo and seven other cells, including the polar bodies that fuse with another sperm nucleus to form endosperm Embryo sac

27 One of the two haploid nuclei in the embryo sac of a seed plant that fuse with a male gamete to form the triploid cell that develops into the endosperm Polar nucleus

28 The cell of a pollen grain that gives rise to the pollen tube
Tube cell

29 In a pollen grain, the cell that divides mitotically and forms two sperm cells
Generative cell

30 A sugar-containing fluid secreted by flowers to attract birds or insects for pollination

31 The process by which one of the two sperm nuclei fuses with the egg nucleus to produce a diploid zygote and the other fuses with the polar nuclei to produce a triploid endosperm Double fertilization

32 The production of new individuals

33 The protective, outer covering of a seed
Seed coat

34 The developing shoot above the cotyledons in plant embryos; consists of the epicotyl and young leaves Plumule

35 The portion of the stem of a plant embryo that is between the cotyledons and the first true leaves

36 The portion of the stem of a plant embryo that is between the cotyledons and the embryonic root

37 In plants, the embryonic, or primary, root

38 On a plant seed, a scar that marks where the seed was attached to the ovary wall

39 A state in which seeds, spores, bulbs, and other reproductive organs stop growth and development and reduce their metabolism, especially respiration Dormancy

40 An organism that is produced by asexual reproduction and that is genetically identical to its parent; to make a genetic duplicate Clone

41 Vegetative Reproduction
A type of asexual reproduction in which new plants grow from nonreproductive plant parts Vegetative Reproduction

42 A root, stem, or leaf that is cut from a living plant and that can produce a new plant

43 The process of causing roots to form on stems or branches of a plant that are covered with soil

44 A technique in which a portion of one plant is attached to the root or shoot of another plant and grows there Grafting

45 The technique for growing living cells in an artificial medium
Tissue culture
