This allows plants that may require an animal pollinator to stand out from other flowers or distinguish where their flowers are in a muddied background of other plant parts. [5] For the plant, it is important to share and receive pollen so they can reproduce, maintain their ecological role, and guide the evolutionary history of the population.
These flowers can be fertilised in eighteen distinct ways, necessitating a vast number of experiments, the result being, as in the case of the cowslip, that flowers fertilised by the pollen from stamens of the same length as the styles, gave on the average a larger number of capsules and a very much larger number of seeds than in any other case.
Myosotis species are annual or perennial, herbaceous, flowering plants with pentamerous actinomorphic flowers with five sepals and petals. [4] Flowers are typically 1 cm (½") in diameter or less, flatly faced, coloured typically blue, but sometimes pink, white or yellow with yellow centres and borne on scorpioid cymes .
Flowers also attract pollinators by scent, though not all flower scents are appealing to humans; several flowers are pollinated by insects that are attracted to rotten flesh and have flowers that smell like dead animals. These are often called carrion flowers, including plants in the genus Rafflesia, and the titan arum.
Some of the colors of autumn leaves are derived from anthocyanins. [1] [2] Anthocyanins belong to a parent class of molecules called flavonoids synthesized via the phenylpropanoid pathway. They can occur in all tissues of higher plants, including leaves, stems, roots, flowers, and fruits. Anthocyanins are derived from anthocyanidins by adding ...
All spermatophytes ("seed plants") possess flowers as defined here (in a broad sense), but the internal organization of the flower is very different in the two main groups of spermatophytes: living gymnosperms and angiosperms. Gymnosperms may possess flowers that are gathered in strobili, or the flower itself may be a strobilus of fertile leaves.

In evolutionary biology, mimicry in plants is where a plant evolves to resemble another organism physically or chemically. Mimicry in plants has been studied far less than mimicry in animals . It may provide protection against herbivory , or may deceptively encourage mutualists, like pollinators , to provide a service without offering a reward ...
