What is zoospores vaucheria?
Zoospores. In vaucheria, asexual reproduction occurs by the large solitary zoospore, during the period of development, the apex of the filament swells up and becomes club-shaped, further, it will be separated from the rest of the filament by septum. The club-shaped body formed is called Zoosporangium.
What is the structure of vaucheria zoospore?
Each zoospore is large yellow green, oval structure. It has a central vacuole which has cell sap and may be traversed by cytoplasmic strands. The protoplasm outer to vacuole has many nuclei towards the walls and chromatophores towards vacuoles. Two flagella arise opposite to each nucleus.
How do you identify vaucheria?
Vaucheria species are characterized by multinucleate tubular branches that lack cross walls except when associated with reproductive organs or when injured. Food is stored as oil globules. Asexual reproduction is by motile multiflagellate zoospores and nonmotile aplanospores.
What flagella is found in vaucheria?
Each nucleus along with some cytoplasm metamorphoses into single spindle shaped biflagellate antherozoid (Fig. 3.87E). The flagella are unequal in length, dissimilar (one whiplash and other tinsel) and laterally inserted.
Why Vaucheria Zoospores are called as compound Zoospores?
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.

What is Gongrosira stage example?
Answer:Sometimes, thin wall divides the contents of aplanospore in to many parts. Each part develops cysts or hypnospores. This stage of Vaucheria is called Gongrosira stage as it resembles the alga Gongrosira. The cyst ruptures in favourable conditions and protoplast comes out by amoeboid movement.

The sexual reproduction in Vaucheria is of Oogamous type. It takes place by antheridium, the male sex organ and oogonium, the female sex organ. Most of the species are homothallic or monoecious but a few (V. litorea, V.
Which type of algae is Vaucheria?
Vaucheria is a genus of Xanthophyceae or yellow-green algae. It is one of only two genera in the family Vaucheriaceae. The type species of the genus is Vaucheria disperma. Vaucheria exhibits apical growth from the tip of filaments forming mats in either terrestrial or freshwater environments.
