Questions and Answers
- 1.
The outer covering tissue of the plant; the epidermis or the periderm.
- 2.
A leaf or leaflike stucture bearing a megasporangium.
- 3.
A leaflike organ bearing one or more microsporangia.
- 4.
In heterosporous plants, a spore that develops into a male gametophyte.
- 5.
The food conducting tissue of vascular plants.
- 6.
All tissues other than the epidermis and the vascular tissues; also called fundamental tissue system.
- 7.
A small leaf with one vein and one leaf trace not associated with either a leaf gap or a leaf trace gap.
- 8.
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.
- 9.
Having only one kind of spore.
- 10.
Region of parenchyma tissue in the primary vascular cylinder above the point of departure of the leaf trace or traces in ferns.
- 11.
A minute outgrowth or appendage at the base of the leaves of grasses and those of certain lycophytes.
- 12.
A stele in which the primary vascular tissues are arranged in discrete strands around a pith.
- 13.
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.
- 14.
Outer protective tissue that replaces epidermis when it is destroyed during secondary growth; includes cork, cork cambium, and phelloderm.
- 15.
A primary division, or leaflet, of a compound leaf or frond; may be divided into pinnules.
- 16.
A generally large leaf with several to many veins; its leaf trace is/are associated with a leaf gap and a leaf trace gap.
- 17.
An elongated, spindle-shaped, sterile cell in the sporangium of a liverwort sporophyte.
- 18.
Region of parenchyma tissue in the primary vascular cylinder above the point of departure of the leaf trace or traces in seed plants.
- 19.
Membranous growth of the epiderm of a fern leaf that covers sori.
- 20.
The leaf of a fern; any large, divided leaf.
- 21.
A sporangium that arises from several initial cells and, before maturation, forms a wall of more than one layer of cells.
- 22.
As in ferns, the coiled arrangement of leaves and leaflets in the bud; such an arrangement uncoils gradually as the leaf develops further.
- 23.
A complex vascular tissue through which most of the water and minerals of a plant are conducted.
- 24.
One of the cells composing a vessel.
- 25.
A cylindrical sheath of meristematic cells, the division of which produces secondary phloem and secondary xylem.
- 26.
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.
- 27.
The general term for a water-conducting cell in vascular plants; tracheids and vessel elements.
- 28.
Nutritive element in the sporangium, particularly an anther.
- 29.
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.
- 30.
A reproductive structure consisting of a number of modified leaves or ovule-bearing scales grouped terminally on a stem; a cone.
- 31.
The central cylinder, inside the cortex, of roots and stems of vascular plants.
- 32.
A modified leaf or leaflike organ that bears sporangia.
- 33.
A branch bearing one or more sporangia.
- 34.
A type of stele containing a hollow cylinder of vascular tissue surrounding a pith.
- 35.
The above-ground portions, such as the stem and leaves, of a vascular plant.
- 36.
A structure formed by the maturation of the ovule of seed plants following fertilization.
- 37.
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.
- 38.
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.
- 39.
The simplest type of stele, consisting of a solid column of vascular tissue.
- 40.
In homosporous vascular plants, such as ferns, the more or less independent, photosynthetic gametophyte.
- 41.
Cells derived from the apical meristems and primary meristematic tissues of root and shoot; results in an increase in length.
- 42.
The part of the plant body arising from the apical meristems and their derivative meristematic tissues.
- 43.
In plants, growth originating in the apical meristems of shoots and roots.
- 44.
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.
- 45.
A tube formed after germination of the pollen grain; carries the male gametes into the ovule.
- 46.
A microspore containing a mature or immature microgametophyte.
- 47.
The ground tissue occupying the center of the stem or root within the vascular cylinder; usually consists of parenchyma.
- 48.
Type of life history associated with seedless vascular plants.
- 49.
Phyla that includes the club mosses.
- 50.
Phyla that includes the ferns.
