Metallurgy, bar of puddled iron.
Whitish powdery or waxlike coating over the surface of certain fruits that easily rubs off when handled. It often contains yeasts that live on the sugars in the fruit. The term bloom is also used to describe a rapid increase in number of certain species of algae found in lakes, ponds, and oceans.
Such blooms may be natural but are often the result of nitrate pollution, in which artificial fertilizers, applied to surrounding fields, leach out into the waterways. This type of bloom can lead to the death of almost every other organism in the water; because light cannot penetrate the algal growth, the plants beneath can no longer photosynthesize and therefore do not release oxygen into the water. Only those organisms that are adapted to very low levels of oxygen survive.

The reproductive unit of an angiosperm or flowering plant, typically consisting of four whorls of modified leaves: sepals, petals, stamens, and carpels. These are borne on a central axis or receptacle. The many variations in size, color, number, and arrangement of parts are closely related to the method of pollination. Flowers adapted for wind pollination typically have reduced or absent petals and sepals and long, feathery stigmas that hang outside the flower to trap airborne pollen. In contrast, the petals of insect-pollinated flowers are usually conspicuous and brightly colored.
The sepals and petals form the calyx and corolla respectively and together comprise the perianth with the function of protecting the reproductive organs and attracting pollinators.
The stamens lie within the corolla, each having a slender stalk, or filament, bearing the pollen-containing anther at the top. Collectively they are known as the androecium (male organs). The inner whorl of the flower comprises the carpels, each usually consisting of an ovary in which are borne the ovules, and a stigma borne at the top of a slender stalk, or style. Collectively the carpels are known as the gynoecium (female organs).
In size, flowers range from the tiny blooms of duckweeds scarcely visible to the naked eye to the gigantic flowers of the Malaysian Rafflesia, which can reach over 1 m/3 ft across. Flowers may either be borne singly or grouped together in inflorescences. The stalk of the whole inflorescence is termed a peduncle, and the stalk of an individual flower is termed a pedicel. A flower is termed hermaphrodite when it contains both male and female reproductive organs. When male and female organs are carried in separate flowers, they are termed monoecious; when male and female flowers are on separate plants, the term dioecious is used.
