Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes. [1] Early Greek philosophers studied pattern, with Plato ...
A flower, also known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae).Flowers consist of a combination of vegetative organs – sepals that enclose and protect the developing flower, petals that attract pollinators, and reproductive organs that produce gametophytes, which in flowering plants produce gametes.
A floral diagram is a graphic representation of the structure of a flower. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding angiosperm evolution.
Among these are: bilateral symmetry of the flower (zygomorphism), many resupinate flowers, a nearly always highly modified petal (labellum), fused stamens and carpels, and extremely small seeds. Stem and roots Germinating seeds of the temperate orchid Anacamptis coriophora. All orchids are perennial herbs that lack any permanent woody structure ...
UV coloration is a natural phenomenon that leads to unique interactions between organisms that have evolved the ability to perceive these wavelengths of light. It serves as one method to attract pollinators to the flower along with scent, shape, and nectar quality. [1] Flowers are known for their range of visible colors that humans can see with ...
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (/ ˌ æ n dʒ i ə ˈ s p ər m iː /), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees , shrubs and vines , and most aquatic plants .
An individual flower is 5–6 mm (3 ⁄ 16 – 1 ⁄ 4 in) long and 8–11 mm (5 ⁄ 16 – 7 ⁄ 16 in) wide. Protandrous , bisexual flowers and male flowers exist on the same individual tree. The fruit is a smooth ( glabrous ), olive-like drupe which varies in shape from elongate oval to nearly roundish, and when ripe is 14–28 mm ( 1 ⁄ 2 ...
Achillea millefolium, commonly known as yarrow ( / ˈjæroʊ /) or common yarrow, is a flowering plant in the family Asteraceae. Growing to 1 metre ( feet) tall, it is characterized by small whitish flowers, a tall stem of fernlike leaves, and a pungent odor. The plant is native to temperate regions of the Northern Hemisphere in Asia, Europe ...
