As it is a delicate structure therefore need protection hence it is covered from outside with a bony structure called skull. Chlorophyceae (Green algae) General characterstics of Chlorophyceae. It was considered in the earlier literature that there are only two orders e.g. CLASSIFICATION OF ALGAE . Inside skull Brain is covered by Cranial Meninges which function as a protective layer. In addition, algae may occur in moist soil or on the surface of moist rocks and wood. Human Brain Cover Our Brain is soft and delicate structure and its shape seems as walnut. Botrydium. For instance, algae living in snow contain carotenoid pigments in addition to chlorophyll, hence giving the surrounding snow a distinctive red hue. Algae (singular alga) is a term that involves many different groups of living organisms. classification of algae was given by F.E Fritsch (1935) in his book ‘The Structure and Reproduction of the Algae’.

According to these morphological and physiological differences they are classified by many people. In the Whittaker system of classification for all Fritsch’s Classification of Algae: F.E. , he does not consider algae as a kingdom he considers it equivalent to the importance of pigments. The use of algae in integrated aquaculture has also been recently reviewed by Turan (2009). But Smith divided it into 3 orders. Ø Different groups of algae have different pigment composition. Chrysophyceae. Blue Green Algae Classification. The classification of algae proposed by Smith (1933, 51, 55) is based on the physiological characters of vegetative cells and the morphology of motile reproductive cells. In their classification it is also used the comparison of their genomes to show evolutionary history.

These are now known to contain several quite different organisms from Euglena to … ALGAE are thalloid structure, containing chlorophyll, These are Chlorophycophyta, Xanthophycophyta, Bacillariophycophyta, Phaeophycophyta, Rhodophycophyta, Chrysophycophyta, Euglenophycophyta, Cryptophycophyta and Pyrrophycophyta. Just as humans move from one place to another using our legs, algae move from one … Identification of Algae in Water Supplies Section I Continue George Izaguirre The algae are a large and very diverse group of organisms that rangefrom minute single-celled forms to the giant marine kelps. They have chlorophyll a, c, carotenoids and xanthophyll pigments. •The current systems of classification of algae are based on the following main criteria: o kinds of photosynthetic pigments, o type or chemical nature of photosynthetic energy storage products o photosynthetic membranes’ (thylakoids) organization and other features of the chloroplasts. The division Cyanophyta includes only one class Cyanophyceae. Photosynthetic pigments: They possesses chlorophyll a, chlorophyll b and small amount of β-carotenoids. Who doesn't love being #1? For example, some phycologists place the classes Bacillariophyceae, Phaeophyceae, and Xanthophyceae in the division Chromophyta, whereas others place each class in separate divisions: Bacillariophyta, Phaeophyta, and Xanthophyta. girls college, Kota For solving any problem we have to understand that problem first, but when we talk about The problem of country which means the problem of 130 crore population, then it become complex. Algae capture light energy through photosynthesis and convert inorganic substances into simple sugars using the captured energy. on 23 species of beetles, 101 algal different Asked by Wiki User.

The non motile forms may occur in several classes of algal like Chlorophyceae (Chlorella), Cyanophyceae (Spirulina), Diatoms, Xanthophyceae and Rhodophyceae (Porphyridium). These divisions include one or more classes. The separation of these three groups is so deep and substantial that in recent classification schemes they are classified into different kingdoms. organisms' FIVE kingdoms were kept forth. Mueller matrix images of 12 species of algae from 5 families were measured by a Mueller matrix microscopy with an LED light source at 514 nm wavelength.
