Algae are primarily classified into the following types: Algae are neither bacteria nor plants. [22], In the first three of these groups (Chromista), the chloroplast has four membranes, retaining a nucleomorph in cryptomonads, and they likely share a common pigmented ancestor, although other evidence casts doubt on whether the heterokonts, Haptophyta, and cryptomonads are in fact more closely related to each other than to other groups. Harmful Algal Blooms | US EPA algae - Form and function of algae | Britannica Furthermore, once the algae attach, they grow very well, producing a green clump several millimetres thick. True or false: Cell membranes are rigid, static structures that lend stability to cells. Algae exist in environments ranging from oceans, rivers, and lakes to ponds, brackish waters and even snow. Macroalgae, commonly known as seaweed, also have many commercial and industrial uses, but due to their size and the specific requirements of the environment in which they need to grow, they do not lend themselves as readily to cultivation (this may change, however, with the advent of newer seaweed cultivators, which are basically algae scrubbers using upflowing air bubbles in small containers). As a result, researchers are looking into renewable alternatives. Although cyanobacteria are often referred to as "blue-green algae", most authorities exclude all prokaryotes from the definition of algae. [8], Algae lack the various structures that characterize land plants, such as the phyllids (leaf-like structures) of bryophytes, rhizoids of nonvascular plants, and the roots, leaves, and other organs found in tracheophytes (vascular plants). From an economical perspective, algae are very useful for creating biomass or fertilizers as they grow very fast.
