Algae are simple plants that can range from the microscopic microalgaeto large seaweeds macroalgaesuch as giant kelp more than one hundred feet in length.
The cells of eukaryotic microbes are similar to plant and animal cells in that their DNA is enclosed within a nuclear membrane, Algae growth the nucleus.
Eukaryotic microorganisms include algae, protozoa, and fungi. Collectively algae, protozoa, and some lower fungi are frequently referred to as… In this article the algae are defined as eukaryotic nucleus-bearing organisms that photosynthesize but lack the specialized multicellular reproductive structures of plants, which always contain fertile gamete -producing cells surrounded by sterile cells.
Algae also lack true rootsstemsand leaves —features they share with the avascular lower plants e. Additionally, the algae as treated in this article exclude the prokaryotic nucleus-lacking blue-green algae cyanobacteria. Beginning in the s, algae were classified into major groups based on colour—e.
The colours are a reflection of different chloroplast pigments, such as chlorophyllscarotenoidsand phycobiliproteins.
Many more than three groups of pigments are recognized, and each class of algae shares a common set of pigment types distinct from those of all other groups.
The green algae Ulva lactuca, commonly known as sea lettuce, is easily harvested when it is exposed at low tide.
Many people living in coastal societies consume sea lettuce in salads and soups. Alison Wilson The algae are not closely related in an evolutionary sense, and the phylogeny of the group remains to be delineated.
Specific groups of algae share features with protozoa and fungi that, without the presence of chloroplasts and photosynthesis as delimiting features, make them difficult to distinguish from those organisms.
Indeed, some algae appear to have a closer evolutionary relationship with the protozoa or fungi than they do with other algae. Heather Angel This article discusses the algae in terms of their morphologyecology, and evolutionary features.
For a discussion of the related protists, see the articles protozoan and protist. For a more complete discussion of photosynthesis, see the articles photosynthesis and plant. Page 1 of In most algal growth cultivation, algae only need about 1/10 of direct sunlight.
In most water systems, light only penetrates the top cm of water. This is due to bulk algal biomass, which blocks light from reaching into deeper water. Too much of algae can turn the surface of fish tanks, ponds, and lakes green; causing a problem for the ecosystem. This article will give you an insight on what causes the growth, and effective ways of .
Algae (/ ˈ æ l dʒ i, ˈ æ l ɡ i /; singular alga / ˈ æ l ɡ ə /) is an informal term for a large, diverse group of photosynthetic eukaryotic organisms that are not necessarily closely related, and is thus ashio-midori.comed organisms range from unicellular microalgae genera, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which.
Other algae can grow in the dark using sugar or starch (called “heterotrophic” growth), or even combine both growth modes (called “mixotrophic” growth). Algae are very diverse and found almost everywhere on . As water storage becomes more important, so does maintaining a healthy, safe supply.
Algae is a common culprit in water safety and will cause your harvested water supply to become unusable.. Algae is a bacteria containing harmful toxins affecting animals, humans, and plants..
Chemical Treatments. Algae-based Wastewater Treatment. Compiled by a diverse team of experts, with experience in scientific and industrial fields, the Comprehensive Report for Wastewater Treatment Using Algae is the first report that provides in-depth analysis and insights on this important field.
