Seedless Vascular Plants

1. A complex vascular tissue through which most of the water and minerals of a plant are conducted.

2.

What first name or nickname would you like us to use?

2. The food conducting tissue of vascular plants.

3. A tube formed after germination of the pollen grain; carries the male gametes into the ovule.

4. The sporangia commonly occurs in clusters on the underside of leaves.

5. In heterosporous plants, a spore that develops into a male gametophyte.

6. A cylindrical sheath of meristematic cells, the division of which produces secondary phloem and secondary xylem.

7. A small leaf with one vein and one leaf trace not associated with either a leaf gap or a leaf trace gap.

8. Outer protective tissue that replaces epidermis when it is destroyed during secondary growth; includes cork, cork cambium, and phelloderm.

9. The simplest type of stele, consisting of a solid column of vascular tissue.

10. Having only one kind of spore.

11. In angiosperms, the transfer of pollen from an anther to a stigma. In gymnosperms, the transfer of pollen from a pollen-producing cone directly to an ovule.

12. A generally large leaf with several to many veins; its leaf trace is/are associated with a leaf gap and a leaf trace gap.

13. A modified leaf or leaflike organ that bears sporangia.

14. In plants, growth originating in the apical meristems of shoots and roots.

15. The leaf of a fern; any large, divided leaf.

16. The ground tissue occupying the center of the stem or root within the vascular cylinder; usually consists of parenchyma.

17. Stalk of a leaf.

18. The lateral meristem that forms the periderm, producing cork toward the surface of the plant and phelloderm toward the inside; common in stems and roots.

19. Region of parenchyma tissue in the primary vascular cylinder above the point of departure of the leaf trace or traces in ferns.

20. A structure formed by the maturation of the ovule of seed plants following fertilization.

21. An elongated, thick-walled conducting and supporting cell of xylem. It has tapering ends and pitted walls without perforations, as contrasted with a vessel element.

22. Phyla that includes the ferns.

23. In ferns, a row of specialized cells in a sporangium; in gill fungi, the remnant of the inner veil forming a ring on the stalk.

24. Main axis of a spike; the axis of a fern leaf from with the pinnae arise; in compound leaves, the extension of the petiole corresponding to the midrib of an entire leaf.

25. A microspore containing a mature or immature microgametophyte.

26. Region of parenchyma tissue in the primary vascular cylinder above the point of departure of the leaf trace or traces in seed plants.

27. A stele in which the primary vascular tissues are arranged in discrete strands around a pith.

28. A minute outgrowth or appendage at the base of the leaves of grasses and those of certain lycophytes.

29. Underground stem, the belowground portion of the plant axis, bearing rhizoids for water absorption.

30. The above-ground portions, such as the stem and leaves, of a vascular plant.

31. In homosporous vascular plants, such as ferns, the more or less independent, photosynthetic gametophyte.

32. A leaf or leaflike stucture bearing a megasporangium.

33. One of the cells composing a vessel.

34. A type of stele containing a hollow cylinder of vascular tissue surrounding a pith.

35. The outer covering tissue of the plant; the epidermis or the periderm.

36. A reproductive structure consisting of a number of modified leaves or ovule-bearing scales grouped terminally on a stem; a cone.

37. Young coiled leaves.

38. The central cylinder, inside the cortex, of roots and stems of vascular plants.

39. All tissues other than the epidermis and the vascular tissues; also called fundamental tissue system.

40. Phyla that includes the club mosses.

41. A primary division, or leaflet, of a compound leaf or frond; may be divided into pinnules.

42. The part of the plant body arising from the apical meristems and their derivative meristematic tissues.

43. A leaflike organ bearing one or more microsporangia.

44. Nutritive element in the sporangium, particularly an anther.

45. A sporangium that arises from several initial cells and, before maturation, forms a wall of more than one layer of cells.

46. Membranous growth of the epiderm of a fern leaf that covers sori.

47. A branch bearing one or more sporangia.

48. An elongated, spindle-shaped, sterile cell in the sporangium of a liverwort sporophyte.

49. The general term for a water-conducting cell in vascular plants; tracheids and vessel elements.

50. A structure at the base of the embryo in many vascular plants. In some plants, it pushes the embryo into nutrient-rich tissue of the female gametophyte.

51. Type of life history associated with seedless vascular plants.

52. As in ferns, the coiled arrangement of leaves and leaflets in the bud; such an arrangement uncoils gradually as the leaf develops further.

53. Cells derived from the apical meristems and primary meristematic tissues of root and shoot; results in an increase in length.

54. An organism with branched axis and multiple sporangia but with water-conducting cells similar to the hydroids of modern mosses rather than to the tracheary elements of vascular plants.

55. The sporophylls occur in compact aggregates called cones or strobili.
