What is the importance of chlorophyceae?
The green algae are not so economically important except a few members. Among them Chlorella is very important because of its high protein content, presence of vitamins and its use in baking industry in the preparation of cake, pastries etc.
What is the economic significance of the algae?
Algae are economically important in a variety of ways. The natural substance can be used as a food source, a fodder, in fish farming, and as a fertilizer. It also plays a key role in alkaline reclaiming, can be used as a soil binding agent, and is used in a variety of commercial products.
What is the economic importance of blue green algae?
Blue green algae (BGA) possess immense morphological and metabolic diversity and can be used in economic development and environment management like wastewater treatment, land reclamation, production of fine chemicals, atmospheric fixation of nitrogen, production of methane fuel, conversion of solar energy, therapeutic …
What are the four economic importance of algae?
Food: Algae are a healthy source of carbohydrates, fats, proteins, and vitamins A, B, C, and E as well as the minerals like iron, potassium, magnesium, calcium, manganese, and zinc.
What is the economic importance of diatoms?
(a) Diatoms are an important source of food to aquatic animals. (b) Diatom deposits are often accompained by petroleum fields. (c) Diatomite is porous and chemically inert,therefore used in filtration of sugar, alcohols and antibiotics. (d) It is also employed as a cleansing agent in tooth pastes and metal polishes.
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 economic importance of algae and Gymnosperm?
Hint: Algae and gymnosperms are used for several commercial purposes. Both of these are used as a food source. In addition, algae are used as an emulsifier in several products and other things whereas gymnosperms are used as a primary source of wood for construction purposes and other activities.
What are the five economic importance of fungi?
Fungi are an important organism in human life. They play an important role in medicine by yielding antibiotics, in agriculture by maintaining soil fertility, are consumed as food, and forms the basis of many industries.
What are economic importance of Chrysophytes?
It takes nutrient from one region, its decaying dead matter and distributes these nutrients to other part of the water body. It helps in sustaining biodiversity. The food storage product of chrysophytes are oils or polysaccharide laminarin.
What are two economic importance of diatomaceous earth?
Diatomaceous earth is the sedimentary deposit of fossil remains of diatoms. It is used in the treatment of high cholesterol, constipation and is given orally. It is used to brush teeth or remove unwanted dead skin cells. It is also used in filtration.
What is the major pigment of chlorophyceae?
| Class | Common Name | Major Pigments |

| Chlorophyceae Phaeophyceae Rhodophyceae | Green algae Brown algae Red algae | Chlorophyll-a and chlorophyll-b. Chlorophyll-a, chlorophyll -c, Fucoxanthin. Chlorophyll-a, chlorophyll-d. Phycoerythrin. |
What is the life cycle of chlorophyceae?
This type is found in all chlorophyceae. In such cases the somatic phasse (plant) is haploid (Gametophyte) while the diploid phase (sporophte) is represented by zygote. During germination the zygote (2n) divides meiotically producing haploid (n) zoospores, which develop into individual plant.
What is Chlorophyceae (green algae)?
Introduction to Chlorophyceae (Green Algae) 2. Occurrence of Chlorophyceae 3. Characteristics 4. Thallus Organisation 5. Classification 6. Economic Importance. Chlorophyceae (chloros, green; phyceae, algal organisation) is commonly known as green algae’.
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 the importance of Chlorella in food?
Among them Chlorella is very important because of its high protein content, presence of vitamins and its use in baking industry in the preparation of cake, pastries etc. It is also used in the preparation of an antibiotic, chlorellin; which is used to control bacteria. It is also used in different physiological experiments.
Which of the following is the only diploid structure in Chlorophyceae?
The zygote or oospore is the only diploid structure in their life cycle. The class Chlorophyceae shows a range of variation in the structure of plant body (thallus). It ranges from unicellular e.g., Chlamydomonas, Chlorella, Sphaerella etc. to multicellular structure. The multicellular forms may be of different types.
