Complete flower
Definition
a flower with sepals, petals, stamen, and pistil. An incomplete flower lacks one or more of these parts.
Term
Determinate growth
Definition
growth or flowering that proceeds in the growing season and then stops (e.g., processing tomatoes).
Term
Dioecious plant
Definition
staminate (male) flowers and pistillate (female) flowers borne on separate plants.
Term
Flower
Definition
specialized leaves adapted for sexual reproduction.
Term
Fruit
Definition
fertilized portion of a flower where seeds are borne.
Term
Imperfect flower
Definition
a flower lacking either stamens or pistils.
Term
Indeterminate growth
Definition
growth or flowering that is not terminated (e.g., fresh market tomatoes).
Term
Inflorescence
Definition
an arrangement of flowers.
Term
Monoecious plant
Definition
stamens and pistils on the same plant.
Term
Ovary- ovule (egg)
Definition
bearing part of a flower. At maturity, the ovary becomes the fruit. Important in plant classification is the position of the ovary relative to the sepals, petals, and stamen. A superior ovary is attached to the receptacle (thickened part of a stem from which the flower grow) above the attachment of other floral parts. An inferior ovary is positioned below the attachment of other floral parts. Half-inferior is in-between.
Term
Perfect flower
Definition
a flower with both stamen and a pistil.
Term
Petals
Definition
Floral leaves inward of sepals. Collectively they form the corolla.
Term
Pistil
Definition
female part of the flower containing the ovary. It consists of a stigma, which receives pollen, a style, which connect the stigma and ovary, and the ovary. A pistil can be simple (one unit called a carpel) or compound (more than one carpel); for example, a cherry has one carpel while there are multiple carpels in apples and tomatoes).
Term
Sepals
Definition
leaf-like scales that encircle the other flower parts. Collectively they form the calyx.
Term
Stamen
Definition
pollen-bearing flower part consisting of a filament (small stem) and anther, which bears the pollen (male sex cell).
