Chlorococcales is a formerly recognized order of green algae in the class Chlorophyceae. As of February 2022, the type family Chlorococcaceae was placed in the order Chlamydomonadales.
Which algae belongs to class Chlorophyceae?
Volvox belongs to chlorophyceae green algae, Spirogyra belongs to zygnematophyceae, Ulothrix belongs to chlorophyceae green algae and Sargassum belongs to brown algae.
Are Chlorophyceae unicellular?
Unicellular flagellated green algae of the genus Dunaliella (Chlorophyceae) are a characteristic component of the biota of most hypersaline environments.
What are the five characteristics of Chlorophyceae?
Characteristics of Class Chlorophyceae:
- Fresh water or marine algae, with unicellular or multicellular body.
- Cells are eukaryotic, containing cellulose in the cell wall.
- Chief pigments include chlorophyll a and b, alpha, beta and gamma carotenes, lycopene, hexanthin, lentin, violaxanthin and astaxanthin.
What is the basic classification of algae write down the various characteristics features of Chlorophyceae?
The Chlorophyceae are one of the classes of green algae, distinguished mainly on the basis of ultrastructural morphology. They are usually green due to the dominance of pigments chlorophyll a and chlorophyll b….
|Class:||Chlorophyceae Wille in Warming, 1884|
What are the important features and life history Chlorophyceae?
Chlorophyceae is very large group of algae and is represented by about 429 genera and 6500 species. Chlorophyceae are mainly fresh water algae (about 90 percent species are fresh water and 10 percent marine). Fresh water forms are common in ponds, pools, lakes, ditches, water tanks, and in river and canals.
What are the characteristics features of Chlorophyceae?
- the body may be unicellular, colonial, filamentous or multicellular.
- They are usually green due to the presence of chlorophyll a, chlorophyll b and beta-carotene.
- The chloroplast may be discoid, cup-shaped (e.g. Chlamydomonas), spiral or ribbon shaped.

What are the salient features of Chlorophyceae?
The salient features of Chlorophyceae members:
- Chlorophyceae commonly called as green algae.
- Mostly aquatic (fresh water or marine), few terrestrial.
- Shape of chloroplast differs.
- Chlorophyll ‘a’ and ‘b’ are photosynthetic pigments.
- Pyrenoids store starch & also proteins.
What are the pigments found in Chlorophyceae?
(i) In chlorophyceae, the stored food material is starch and the major pigments are chlorophyll a and d.
What is Thallus structure of Chlorophyceae?
Thallus Organisation of Chlorophyceae (Green Algae): It ranges from unicellular e.g., Chlamydomonas, Chlorella, Sphaerella etc. to multicellular structure. The multicellular forms may be of different types. They may have a number of cells arranged in colonies of definite shape, the coenobium.

What is the habitat of Chlorophyceae?
The members of Chlorophyceae generally grow in fresh water (about 90%) and the rest in saline water, terrestrial habitat etc. The fresh water members such as Volvox, Oedogonium, Spirogyra etc. grow in ponds, pools and lakes.

What is Chlorophyceae in biology?
Definition of Chlorophyceae : a class of algae (division Chlorophyta) distinguished chiefly by having a clear green color, their chlorophyll being masked or altered little or not at all by other pigments.
What is Chlorophyceae Phaeophyceae and Rhodophyceae?
Chlorophyceae is a class of green algae primarily found in freshwater. Phaeophyceae is a class of brown algae which are almost all marine algae. Rhodophyceae is a class of red algae which are predominantly marine algae.
What is the difference between chlorophyceae & Rhodophyceae?
The Green algae which found in fresh water and in marine habitat are the members of group is known as Chlorophyceae. A group of red algae which belongs to this class is known as Rhodophyceae.
What are some examples of chlorococcalean green alga?
Another extant chlorococcalean green alga that is also known from the fossil record is Scenedesmus. It consists of cylindrical cells with rounded or pointed ends that are joined laterally into 4- to 16-celled coenobia. Two fossil species.
What is the difference between Chlorococcales and Chlorophyceae?
Not to be confused with Chroococcales. Chlorococcales is an order of green algae in the class Chlorophyceae. Individual specimens are sometimes found in soil, but mostly in fresh and marine waters. The order contains approximately 780 species.
How many species of algae are green in colour?
Some species are found in aquatic habitats and others are associated with snow or ice, the latter of which become green when the alga is present in quantity. About 20 species are recorded.
What does Chlorococcales mean?
Chlorococcales is an order of green algae in the class Chlorophyceae. Individual specimens are sometimes found in soil, but mostly in fresh and marine waters.
