Questions and Answers
- 1.
Having the anthers and carpels produced in separate flowers on the same individual.
- 2.
A cavity within a sporangium or a cavity of the ovary in which ovules occur.
- 3.
A flower cluster, with a definite arrangement of flowers.
- 4.
The stalk of the ovule.
- 5.
The stalk of a stamen.
- 6.
The outer wall layer of a spore or pollen grain.
- 7.
A pattern of floral organization in which the sepals, petals, and stamens apparently grow from the top of the ovary.
- 8.
A tissue, containing stored food, that develops from the union of a male nucleus and the polar nuclei of the central cell; it is digested by the growing sporophyte either before or after the maturation of the seed; found only in angiosperms.
- 9.
The female gametophyte of angiosperms, generally an eight-nucleate, seven-celled structure; the seven cells are the egg cell, two synergids and three antipodals, and the central cell.
- 10.
The egg cell and synergids located at the micropylar end of the female gametophyte, or embryo sac, of angiosperms.
- 11.
The fusion of the egg and sperm and the simultaneous fusion of the second male gamete with the polar nuclei; a unique characteristic of all angiosperms.
- 12.
The opening of an anther, fruit, or other structure, which permits the escape of reproductive bodies contained within.
- 13.
The petals collectively.
- 14.
The region of an ovule or seed where the funiculus unites with the integuments and the nucellus.
- 15.
Relatively large vacuolate cells in a subsurface position in apical meristems of shoots.
- 16.
Pertaining to a flower with one or more carpels but no functional stamens; also called a pistillate.
- 17.
One of the members of the gynoecium, or inner floral whorl; encloses one or more ovules.
- 18.
The sepals collectively; the outermost flower whorl.
- 19.
Three cells of the mature embryo sac, located at the end opposite the micropyle.
- 20.
The pollen-bearing portion of a stamen.
- 21.
The floral whorl that comprises the stamens.
- 22.
In angiosperms, the fusion of the second male gamete, or sperm, with the polar nuclei, resulting in the formation of a primary endosperm nucleus, which is triploid in most groups.
- 23.
Nutritive tissue in the sporangium, particularly an anther.
- 24.
A slender column of tissue that arises from the top of the ovary and through which the pollen tube grows.
- 25.
The region of a carpel that serves as a receptive surface for pollen grains and on which they germinate.
- 26.
Pertaining to a flower having stamens but no functional carpels.
- 27.
The part of the flower producing the pollen, composed of anther and filament.
- 28.
The tough substance of which the exine, or outer wall, of spores and pollen grains is composed; a cyclic alcohol highly resistant to decay.
- 29.
One of the outermost flower structures, a unit of the calyx, usually enclose the other flower parts in the bud.
- 30.
The part of the axis of a flower stalk that bears the floral organs.
- 31.
The result of the fusion of a sperm nucleus and the two polar nuclei.
- 32.
The transfer of pollen from an anther to a stigma.
- 33.
A cavity in the anther that contains the pollen grains.
- 34.
Two nuclei, one derived from each end of the embryo sac, which become centrally located; they fuse with a male nucleus to form the primary endosperm nucleus.
- 35.
The manner of ovule attachment within the ovary.
- 36.
The part of the ovary wall to which the ovules or seeds are attached.
- 37.
A term sometimes used to refer to an individual carpel or a group of fused carpels.
- 38.
A flower part, usually conspicuously colored; one of the units of a corolla.
- 39.
A form of floral organizations in which the sepals, petals, and stamens are attached to the margin of a cup-shaped extension of the receptacle; superficially, the sepals, petals, and stamens appear to be attached to the ovary.
- 40.
The fruit wall, which develops from the mature ovary wall.
- 41.
The petals and sepals taken together.
- 42.
The stalk of an inflorescence or of a solitary flower.
- 43.
The stalk of an individual flower in an inflorescence.
- 44.
The inner wall layer of a spore or pollen grain.
- 45.
Group that contains the Bryophytes, Fungi, & Algae.
- 46.
Group that includes the seed producers and where pollination is a must.
- 47.
Phylum that makes up the angiosperms.

General term for a flower with both stamens and carpels(bisexual).
- 49.
General term for a flower that lacks either stamens or carpels(unisexual).
