The saclike part of the stamen on seed-producing plants that develops and contains the pollen.
Group of sepals on a flower.
A substance present in all green plants; it evidences itself as the green coloring in leaves.
Chlorophyll transforms light energy from the sun into chemical energy for the manufacture of plant food from
carbon dioxide, water, and essential soil minerals. This process is called photosynthesis.
Minute objects within plant cells that contain the green pigment, chlorophyll.
A flower containing sepals, petals, stamens, and at least one pistil.
Collectively, all of the petals of the flower.
Any organism in its earliest stages of development.
The uniting of pollen and ovule cells.
The part of the stamen of a flower that is below the anther and supports it.
The reproductive structure of a seed-bearing plant, consisting of the male and/or female organs that
are surrounded by one or two series of outer coverings.
Mature ovary, seed.
Sprouting of a seed, and beginning of plant growth.
Percentage of seeds that sprout and begin to grow.
Flower that lack either stamens or pistils.
A flower that lacks one or more of the four organs: sepals, petals, stamens, or pistils.
A flattened outgrowth from a plant stem, varying in size and shape, usually green, which is concerned
primarily with the manufacture of carbohydrates by photosynthesis.
Substance necessary for the functioning of an organism.
The portion of the pistil or carpel of a flower that contains one or more ovules.
The body that, after fertilization, becomes the seed; the egg-containing unit of the ovary.
A flower with both stamens and a pistil or pistils.
A division of a flower inside the calyx; a unit of the corolla, consisting of petioles, which usually
surrounds the pistils and stamens.
Process by which green plants, using chlorophyll and the energy of sunlight, produce
carbohydrates from water and carbon dioxide, and release oxygen.
The female element of a flower; composed of stigma, style, and ovary.
Designating a flower that has a pistil or pistils but lacks stamens; an imperfect flower.
The male element that carries the spores in the fertilization of the egg nucleus in the ovule of a flower.
The pollen is borne by the anthers and is usually a yellowish, dust-like mass of separate grains.
Tube formed following the germination of a pollen grain, when the grain resides on the stigma of
a flower. The tube carries the male gametes to the ovule.
The transfer of the pollen from the anther to the stigma of a flower, the first step in producing a
fruit or seed.
The making of a new plant or animal.
A chemical process that takes place in living cells whereby food (fats, carbohydrates, and
proteins) is "burned" (oxidized) to release energy and waste products, mainly carbon dioxide and water. Living
things use energy produced through respiration to derive vital life processes, such as growth and reproduction.
The lower portion of a plant bearing neither leaves nor reproductive organs that mostly develops
underground and anchors the plant in the soil. It bears the root hairs, which absorb water and mineral
The embryo of a plant; also kernel of corn, wheat, etc., which botanically are seed-like fruits as they
include the ovary wall.
Small, green, leaf-life structure found at the base of a flower.
Union of an egg and sperm to produce a seed or fertilized egg.
The organ of a flower which bears the pollen (microspores) consisting of the stalk (filament) and the
Designating a flower that has stamens but no pistil and hence is imperfect.
Stalk, trunk, branch of a plant. Can be vertical or horizontal.
The receptive surface of the female organ of a flower that receives the pollen.
In the pistil of a flower, the part between the ovary and the stigma.
Any herbaceous plant whose fruit, seeds, roots, tubers, bulbs, stems, leaves, or flower parts are
used as food.
