What exactly are algae classified? Classification of organisms regarding algae

The more common algae mainly include: ground fungus, hair cabbage, kudzu rice, and large spirulina in cyanobacteria; green seaweed, moss, ulva in green algae; nori and cauliflower in red algae; Kelp in brown algae, wakame.

DistributionAlgae have a wide range of distribution, are not strict to environmental conditions, and are highly adaptable, and can live with only very low nutrient concentrations, very low light intensity and fairly low temperatures. It grows not only in rivers, streams, lakes and oceans, but also in temporary stagnant water or wet places.

From the tropics to the poles, from snow-capped mountains to warm springs, from moist ground to not very deep soils, algae can be found almost everywhere. There are marine species of algae in all phyla except for the phylum Royaphyta.

1. Chrysophyta: commonly found in low-temperature freshwater, the color is golden yellow or golden brown. 2. Xanthophyta:

It is mainly distributed in fresh water and humid places. 3. Diatoms: Diatoms are the food of aquatic animals, and they will be deposited as diatomaceous earth after death.

4. Brown algae: mostly distributed in seawater, and the color is mostly brown. 5. Dinoflagellates:

It is mostly produced in the ocean.

1. Chrysophyta

The phylum Chrysophyta is commonly found in fresh water with low water temperature, the plant body is a single cell or a group, without a cell wall, and there is more lutein in the cell than chlorophyll, so the color is mostly golden yellow or golden brown, also known as golden algae starch, golden algae kelp sugar.

2. Xanthophyta:

Xanthellae grow mostly in spring, mainly distributed in fresh water, damp tree trunks, walls, the color is mostly yellow-green, because the cells contain two different flagella, Xanthellae phylum is also known as unequal flagellated algae.

3. Diatom phylum

Diatoms are mostly planktonic and widely distributed in seawater and freshwater, and diatoms are the food of aquatic animals, and will be deposited as diatomaceous earth after death, which can be used as fire-resistant and heat-insulating materials.

4. Brown algae

Most of the phylum Brown Algae are distributed in seawater, only 10 species of brown algae are produced in fresh water, and the plant body is composed of multiple cells, and the color is mostly brown.

5. Dinoflagellates:

Dinoflagellates are mostly found in the ocean, and red tides can be formed when they breed near the coastline, and some dinoflagellates will also appear in large numbers in lakes and ponds, and the color is mostly yellow-green or brownish-yellow.

According to the photosynthetic pigments, individual morphology, cell structure, reproductive mode and life history of algae, algae can be divided into 10 phyla: cyanobacteria, euglena, green algae, rotaphyta, golden algae, xanthellophyta, diatoms, dinoflagellates, brown algae and red algae, among which, some algae of cyanobacteria, euglena socks, green algae and diatoms are related to water eutrophication.

Algae are the primary producers in the water body, but also the basic link of the aquatic food chain, under the photosynthesis they absorb the inorganic nutrients and carbon dioxide in the water to produce organic matter, their existence is not only the water production capacity reputation or the self-purification of water pollution is of great significance, therefore, in the study of the impact of reading materials or wastewater on the water environment, algae testing is an important content.

What are the algae plants.

Algae are primitive and ancient lower plants. This type of plant is characterized by a simple structure, and organs such as roots, stems, leaves, flowers, and fruits are not differentiated, but they contain chlorophyll, so they can carry out photosynthesis. Common algae include kelp, red algae, dinoflagellates, yellow algae, diatoms, cyanozoa, green algae, brown algae, golden algae, conch, hijiki, euglena, wakame, etc.

Jackie. The genus Hylan is a plant of the phylum Rhodophyta, about 5-12cm tall. The plants are clustered, with thin stems and cylindrical branches, mostly growing on rocks in the intertidal zone.

The current location of Murphyta, Chlorella is a plant of the phylum Chlorophyta. Its cells are very similar to those of higher plants. They all have nuclei and are mostly found on the surface of fresh or stagnant water with a large chlorophyll content.

Green algae. Golden algae is a type of plant of isoflagellates that is golden-brown in color overall. It is a single-celled swimming variety. This plant contains carotene and natural pigments and prefers to live in water with low temperatures and little organic matter.

Golden algae. Diatoms are a plant of the phylum Diatoms. Its shapes are chain-like, ribbon-like, cluster-like, etc. The whole plant is orange-yellow, and the vegetative body is flagellated. They mostly grow in the open waters of the ocean.

Diatom. Wakame is an algae plant of the phylum Brown Algae. The whole plant is brown and tough. The plant is 1-2m long, with a distinct protrusion in the middle and pinnate lobes on both sides. It grows mainly in areas 1-4 meters below the low tide line.

Algae are autotrophic embryonic plants that can carry out oxygenation photosynthetic reactions, and can be divided into two categories according to cell size.

Algae are a class of eukaryotes in the protist kingdom (some are also prokaryotes, such as the algae of the phylum Cyanobacteria). Mainly aquatic, non-vasculating, capable of photosynthesis. They range in size from single-celled dinoflagellates as small as 1 micron long to large brown algae up to 60 meters long.

Algae may be composed of one or a few cells, or many cells may aggregate into a tissue-like structure. Filaments can branch or not, and some algae are unicellular, while others aggregate into colonies. The green algae of the genus Pine algae are formed by the interweaving of numerous branched filaments, and the morphology and function of the filaments are different in different parts.

Although the algae are mainly aquatic, they are not found in the locust and range from temperate forests to polar plains. Some varieties live in soil and can tolerate long-term water scarcity; Others live in the snow; A few species thrive in hot springs.

Habits of algae:

Most of the algae are aquatic, with seaweed that is native to the ocean; There are also freshwater algae that grow in land water. In aquatic algae, there are planktonic algae that have an enlarged body surface area (e.g., unicellular, swarm, flat, horned, or spiny, etc.), have a smaller specific gravity in the body, or have flagella to adapt to planktonic life.

There are benthic algae that have colloidal in vitro, have sessessation apparatus or false roots at the base, and grow on the bottom substrate of water; There are also ice and snow algae that grow on glacial snow; There are also hot spring algae that live in hot springs with a water temperature of 80 or more. There are also many algae whose algae are not completely submerged in water, some of which are aerial algae whose algae are directly exposed to the atmosphere in part or all of them.

There are also soil algae that grow on or below the surface of the soil. In terms of the relationship between algae and other organisms, there are epiphytic algae that live on the surface of animals and plants; There are also endophytic algae that grow in animals or plants.

There are also symbiotic algae that live in symbiosis with other organisms. In conclusion, the living habits of algae are diverse and adaptable to the environment, and algae are present almost everywhere.
