Types of Algae: Green, Brown and Red Algae (With Diagram) Hence, the red algae are the deepest growing algae in the seas where other photosynthetic forms cannot grow. 3. Red algae appear more red in deep water because of excess phycoerythrin than chlorophyll is formed. When growing in shallow water, they appear green due to more chlorophyll. Structure of Algae (With Diagram) | Algae Biology Discussion Photosynthesis and Storage Food: Photosynthesis in blue green algae occurs in the same manner as in other chlorophyllous plants. The storage food is Cyano­phycean starch (probably amylopectin portion of starch) and proteins. Many of the blue green algae, also store reserve food in the form of oils. Red Algae: Characters and Types (With Diagram) Characters of Red Algae: Red algae are defined as eukaryotic algae which possess chlorophyll a, phycobilins, floridean starch as food reserve, abundant phycocolloids (like agar, carrageenin, and funori) but lack flagellate cells. Cell Structures in Algae (With Diagram) Biology Discussion In this article we will discuss about the cell structures in algae with the help of diagrams. I. Cell Wall: Cell wall of most algae is cellulosic. It also contains hemicellulose, mucilage, pectin and other substances like alginic acid, fucoidin, fucin, calcium carbonate, silica etc. in different combi­nations in different groups of algae. Algae: Definition, Characteristics and Structure (With ... The algae that grow on the surface of the soil are known as saprophytes. Many blue greens, on the other hand, grow under the surface of the soil, and are called cryptophytes. The algae growing in the desert soil may be typified as endedaphic (living in soil), epidaphic (living on the soil surface),... Algae Definition, Characteristics, Types and Examples Algae exist in environments ranging from oceans, rivers, and lakes to ponds, brackish waters, and even snow. Algae are usually green, but they can be found in a variety of different colours. For instance, algae living in snow contain carotenoid pigments in addition to chlorophyll, hence giving the surrounding snow a distinctive red hue. Algae | Facts, Classification, & Examples | Britannica Algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista.

Algae Reproduction and life histories | Britannica Algae Algae Reproduction and life histories: Algae regenerate by sexual reproduction, involving male and female gametes (sex cells), by asexual reproduction, or by both ways. Asexual reproduction is the production of progeny without the union of cells or nuclear material. Many small algae reproduce asexually by ordinary cell division or by fragmentation, whereas larger algae reproduce by ... Algae Algae ( ˈældʒi, ˈælɡi ; singular alga ˈælɡə ) is an informal term for a large, diverse group of photosynthetic eukaryotic organisms that are not necessarily closely related, and is thus polyphyletic.

Chloroplasts are a type of plastid, distinguished by their green color, the result of specialized chlorophyll pigments. In plants, choloroplasts occur in all green tissues. Spirogyra Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. It is commonly found in freshwater habitats, and there are more than 400 species of Spirogyra in the world. ... Fucus Fucus is a genus of brown algae found in the intertidal zones of rocky seashores almost throughout the world. Description and life cycle. The thallus is perennial with an irregular or disc shaped holdfast or with haptera. The erect portion of the thallus is dichotomous or subpinnately ... Diatom Diatoms (diá tom os 'cut in half', from diá, 'through' or 'apart'; and the root of tém n ō, 'I cut'.) are a major group of algae, specifically microalgae, found in the oceans, waterways and soils of the world. algaewheel – Sustainable Wastewater Treatment Algaewheel is a revolutionary technology that uses the natural symbiotic relationship between algae and bacteria to provide high quality treatment with an environmentally responsible footprint. Treats to Highest Standards 2.3. Algal production The key to the success of algal production is maintaining all cultures in the exponential phase of growth. Moreoever, the nutritional value of the produced algae is inferior once the culture is beyond phase 3 due to reduced digestibility, deficient composition, and possible production of toxic metabolites. 2.3.3. The Structure of Algae | Sciencing The word algae refers to a group of organisms that show a great variety in structure and size, ranging from microscopic to over 50 meters in length. In general, they are considered plant like, as they are photosynthetic. They do not, however, have roots or vessels like plants, and are almost always aquatic. Volvox Volvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae.It forms spherical colonies of up to 50,000 cells. They live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700. Volvox diverged from unicellular ancestors approximately PRODUCTION PROCESSES Biodiesel from Algae Algae growth require sunlight, carbon dioxide and water. Photosynthesis is an important bio chemical process in which plants, algae, and some bacteria convert the energy of sunlight to chemical energy. The existing large scale natural sources are of algae are: bogs, marshes and swamps salt marshes and salt lakes. spirogyra | Definition, Structure, Reproduction, & Facts ... Spirogyra, any member of a genus of some 400 species of free floating green algae found in freshwater environments around the world. Named for their beautiful spiral chloroplasts, spirogyras are filamentous algae that consist of thin unbranched chains of cylindrical cells. What is a harmful algal bloom? | National Oceanic and ... Harmful algal blooms, or HABs, occur when colonies of algae — simple plants that live in the sea and freshwater — grow out of control and produce toxic or harmful effects on people, fish, shellfish, marine mammals and birds. The human illnesses caused by HABs, though rare, can be debilitating or even fatal. Ulothrix | Description & Reproduction | Britannica Ulothrix, genus of filamentous green algae (family Ulotrichaceae) found in marine and fresh waters. Each cell contains a distinct nucleus, a central vacuole, and a large thin chloroplast with at least one pyrenoid. The specialized cell for attachment is called the holdfast, and the filaments are typically unbranched.
