Pollination is the transfer of pollen from the stamen to the pistil. Fertilization is the fusion of the male and female gametes (sperm and egg) to form a zygote.

A dicot flower typically has four or five flower parts in each whorl: sepals, petals, stamens, and pistils.

Cereals, like wheat or rice, have flowers grouped in specialized structures such as spikelets, which contain several flowers.

A spikelet is a small inflorescence that forms part of a cereal flower structure. It contains many florets.

Monoecious plants have both male and female flowers on the same plant. Dioecious plants have male flowers on one plant and female flowers on another.

A perfect flower has both male and female reproductive structures. An imperfect flower lacks either the stamen or the pistil.

A complete flower has all four whorls of flower parts: sepals, petals, stamens, and pistils. An incomplete flower lacks one or more of these whorls.

The SAM is a tissue at the tip of the shoot that produces new leaves and stems.

A flowering system consisting of one or more flowering units.

Plant growth stops once flowering starts.

Plant continues vegetative growth even after flowering.

Female reproductive organ of a flower, composed of stigma, style, and ovary.

Male reproductive organ of a flower, composed of anther and filament.

The opening of a plant structure to release contents.

Process of an anther releasing pollen.

Transfer of pollen from anther to stigma.

A plant where male and female flowers are found on separate individuals.

A plant where all flowers have both male and female parts (perfect flowers).

A plant with a mix of perfect and imperfect flowers.

A small unit of an inflorescence in grasses, containing one or more tiny flowers (florets).

Protective bracts that enclose the spikelet in grasses.

A tiny flower within a spikelet of grasses.

Two bracts enclosing the sexual parts of a floret in grasses.

The central axis that bears the florets within a wheat spikelet.

A dry, single-seeded fruit where the seed coat (testa) is fused to the ovary wall (pericarp).

The transfer of pollen by wind, common in plants with abundant pollen and flowers clustered at the top.

An elongate inflorescence with flowers directly attached to the central stalk (rachis).

An unbranched inflorescence with flowers on pedicels attached to a central stalk (rachis), opening from bottom to top.

A branched inflorescence with flowers on pedicels attached to branches that extend from the central stalk (rachis).

An inflorescence with many pedicels originating from the same point, resembling an umbrella.

An inflorescence with many small umbels grouped together, forming a larger, single umbel.

An inflorescence with many small flowers clustered on a common receptacle.

A flower head composed of many small flowers clustered together, often resembling a single large flower.

A type of dry fruit found in grasses, where the seed coat is fused to the ovary wall.

A fruit produced by plants in the pea family, splitting open along two seams.

A fruit formed from two carpels, usually found in plants like cabbage and mustard.

Dicot flowers have evolved various features to attract insects, such as bright colors, nectar, and attractive scents.

A gland in a flower that secretes nectar, a sugary liquid that attracts insects.

Fruit develops after successful pollination and fertilization. The fertilized ovule becomes the seed, while the ovary develops into the fruit.

The embryo is the fertilized ovule, while the seed is the embryo surrounded by protective layers.

A sepal is one of the leaf-like structures that make up the outermost whorl of a flower. They protect the flower bud before it opens.

The calyx refers to the collective term for all the sepals in a flower, forming the outermost whorl.

The corolla is the collective term for all the petals of a flower.

Stamens are the male reproductive organs of a flower, situated inside the petals. Each stamen consists of a filament (stalk) and an anther (pollen-bearing structure).

The androecium is the collective term for all the stamens in a flower.

The carpel or pistil is the female reproductive organ of a flower. It consists of three parts: stigma, style, and ovary.

The gynoecium is the collective term for all the carpels/pistils in a flower.

A flower that has both male (stamen) and female (pistil) reproductive structures.

A flower that has all four whorls of flower parts: sepals, petals, stamens, and pistils.

A flower that lacks one or more of the four whorls of flower parts: sepals, petals, stamens, or pistils.

The fusion of a sperm cell from the pollen grain with the egg cell inside the ovule.

A leaf-like structure that protects the flower bud before it opens. It is part of the outermost whorl of a flower.

An inflorescence where multiple flower stalks (pedicels) emerge from the same point, resembling an umbrella.

Flowers adapted for wind pollination often have clustered flowers at the top of the plant and produce abundant pollen to increase the chances of the pollen reaching another flower.

A flat-topped or round-topped inflorescence characterized by pedicels (flower stalks) that vary in length, resulting in a level top.

The transfer of pollen from one flower to another by insects, a crucial process for the reproduction of most flowering plants.
