Who discovered Vaucheria?

Who discovered Vaucheria?

Name derivation: After Genevan botanist Jean-Pierre-Etienne Vaucher who studied its reproduction (circa 1800). Vaucher was one of the first botanists to consider that such primitive protists (algae) used sexual reproduction. At that time Vaucheria was known as Cryptogames (online).

Which type of algae is Vaucheria?

yellow-green algae
Vaucheria litorea is a species of yellow-green algae (Xanthophyceae).

What is special about Vaucheria?

Vaucheria has distinctive large, multinucleate zoospores with many pairs of unequal flagella. These “compound zoospores” result from incomplete cleavage during the division process that takes place in the apical portion of the filaments.

Where is Vaucheria found?

Vaucheria, genus of yellow-green algae (family Vaucheriaceae), found nearly worldwide. Most species occur in fresh water, though some are marine. The algae can be found in almost any wetland habitat, including mudflats, salt marshes, estuaries, wet farmlands, and pond fringes.

What is the life cycle of Vaucheria?

According to Williams, Hanatsche and Gross the life cycle of Vaucheria is haplontic, the oospore being the only diploid structure in life cycle (Figs. 8, 9). Vaucheria thallus is haploid. It is aseptate, branched, tubular and coenocytic structure.

What is the another name of Vaucheria?

Vaucheria is commonly known as “water felt”; the sparsely branched or unbranched coenocytic filaments often form feltlike mats. The often macroscopic cells contain a large number of discoid plastids, with or without pyrenoids.

What is structure of Vaucheria?

Vaucheria thallus is haploid. It is aseptate, branched, tubular and coenocytic structure. Vegetative re-production takes place by fragmentation. Asexual reproduction takes place by zoospore in aquatic species and by aplanospores in terrestrial species.

Which type of cells are found in Vaucheria?

Vaucheria. The filaments above have developed the beginnings of a branch, while the filament below has two long branches. Vaucheria has siphonaceous, coenocytic filaments that can form feltlike mats, earning it the nickname “water felt”. Cytokinesis does not usually follow mitosis, so the cells retain multiple nuclei.

Why Vaucheria is called the green felt?

Vaucheria or Green Felt, is an alga which appears as a large, dense, dark-green, felted mass of coarse, tubular, branching filaments. It spreads over the mud in shallow ditches and on moist earth near springs or floating on the surface of ponds and in quiet fresh water.
