Plant Parts

Front 1

Complete Flower

Back 1

A flower having all four floral parts: sepals, petals, stamens, and carpels.

Front 2

Incomplete Flower

Back 2

a flower without one or more of the normal parts, as carpels, sepals, petals, pistils, or stamens.

Front 3

Anther

Back 3

the part of a stamen that contains the pollen.

Front 4

filament

Back 4

The stamen of a flower — the part that produces pollen — consists of a slender stalk, called a filament and an anther. The filament supports the anther, which is where pollen develops.

Front 5

stamen

Back 5

The stamen of a flower — the part that produces pollen — consists of a slender stalk, called a filament and an anther. The filament supports the anther, which is where pollen develops.

Front 6

stigma

Back 6

Stigma: The part of the pistil where pollen germinates.

Front 7

style

Back 7

connects stigma to ovary

Front 8

ovule

Back 8

incompletely formed seed

Front 9

ovary

Back 9

Ovary: The enlarged basal portion of the pistil where ovules are produced.

Front 10

fruit

Back 10

In botany, a fruit is the seed-bearing structure in flowering plants (also known as angiosperms) formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate seeds

Front 11

carpel

Back 11

alternate word for pistil The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed.

Front 12

pistil

Back 12

The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed.

Front 13

petal

Back 13

The parts of a flower that are often conspicuously colored.

Front 14

corolla

Back 14

Together, all of the petals of a flower are called a corolla. Petals are usually accompanied by another set of special leaves called sepals, that collectively form the calyx and lie just beneath the corolla. The calyx and the corolla together make up the perianth.

Front 15

sepal

Back 15

one of the individual leaves or parts of the calyx of a flower.

Front 16

calyx

Back 16

set of all the sepals

Front 17

hypanthium

Back 17

The ringlike, cup-shaped, or tubular structure of a flower on which the sepals, petals, and stamens are borne, as in the flowers of the rose or cherry. Also called floral cup.

Front 18

inflorescence

Back 18

Inflorescence, in a flowering plant, a cluster of flowers on a branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (peduncle) and by the timing of its flowering (determinate and indeterminate).

Front 19

regular symmetry

Back 19

Most flowers are actinomorphic ("star shaped", "radial"), meaning they can be divided into 3 or more identical sectors which are related to each other by rotation about the centre of the flower. Typically, each sector might contain one tepal or one petal and one sepal and so on. It may or may not be possible to divide the flower into symmetrical halves by the same number of longitudinal planes passing through the axis: Oleander is an example of a flower without such mirror planes. Actinomorphic flowers are also called radially symmetrical or regular flowers. Other examples of actinomorphic flowers are the lily (Lilium, Liliaceae) and the buttercup (Ranunculus, Ranunculaceae).

Front 20

irregular symmetry

Back 20

A flower in which one or more members of a whorl, or of several floral whorls, differ in form from other members. Irregular flowers, such as those of the violet or the pea, are often bilaterally symmetric. The pea has one large upper petal above, two free petals on the each side, and two petals fused together in a keel shape below.

Front 21

inferioir ovary

Back 21

The petals and sepals are above the ovary; such a flower is said to have an inferior ovary, or the flower is said to be epigynous. Cross section of Tulip ovary. In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium.

Front 22

superior ovary

Back 22

A superior ovary is an ovary attached to the receptacle above the attachment of other floral parts. A superior ovary is found in types of fleshy fruits such as true berries, drupes, etc. A flower with this arrangement is described as hypogynous. An example is Hypericum calycinum.

Front 23

disk flower

Back 23

one of a number of small tubular flowers composing the disk of certain composite plants.

Front 24

ray flower

Back 24

One of the narrow flowers, resembling single petals, that surround the central disk in the capitulum or flower cluster of a plant of the composite family (Asteraceae or Compositae), such as the daisy or sunflower. Rays are often male flowers with sterile stamens. Also called ray , ray floret.
