Pinnularia

Occurrence Pinnularia is a fresh water alga. It is found in pond. It is also present on the moist soil It is unicellular. Its cell is elongated and elliptical. Cell wall is chiefly composed of pectic substances. Silica is impregnated in …

Vaucheria

Occurrence Majority of them are fresh water. They are also found on moist soil. They form dark green mats. General structure Vegetative structure The thallus is filamentous. The filament is cylindrical, branched, tubular, erect coenocytic. The filament is attached to …

Volvox

Occurrence Volvox is freshwater algae. It makes water green. It appears in the spring. Vegetative structure Volvox forms colony. The colony of volvox is called coenobium (if the colony having fixed number of cells). It is spherical in shape. Each …

Chara

Occurrence: Chara is a fresh water, green alga found submerged in shallow water ponds, tanks, lakes and slow running water. C. baltica is found growing is brackish water and C. fragilis is found in hot springs. Chara is found mostly …

Cyanophyceae

The Cyanophyceae or blue-green algae are, today, usually referred to as the cyanobacteria (bluegreen bacteria). The term cyanobacteria acknowledges that these prokaryotic algae are more closely related to the prokaryotic bacteria than to eukaryotic algae. Cyanobacteria have chlorophyll a (some …

Algae Plastids

The basic type of plastid in the algae is a chloroplast, a plastid capable of photosynthesis. Chromoplast is synonymous with chloroplast; in the older literature a chloro plast that has a color other than green is often called a chromoplast. A …

Algae: Flagellation

The flagella of the green alga Chlamydomonas have been used as a model of flagellar structure. Flagella structure has been highly conserved throughout evolution, images from Chlamydomonas are virtually indistinguishable from flagella (or cilia – a term for a short …

Algae: Cell Structure

There are two basic types of cells in the algae, prokaryotic and eukaryotic. Prokaryotic cells lack membrane-bounded organelles (plastids, mitochondria, nuclei, Golgi bodies, and flagella) and occur in the cyanobacteria. The remainder of the algae are eukaryotic and have organelles. A …
