Detailed explanation-1: -In Vaucheria, the multiflagellate compound zoospores also known as synzoospores or coenozoospores are developed in these genus usually in aquatic forms. A single compound zoospore develops in a single zoosporangium.

Detailed explanation-2: -Note: The formation of synzoospore occurs only in the vaucheria. Vaucheria is a member of class Xanthophyceae (yellow-green) algae. The body of Vaucheria consists of an aseptate, tubular, irregularly branched, coenocytic filament. It is usually attached to the substratum by means branched and colourless holdfast.

Detailed explanation-3: -The zoospores become flagellated after liberation. The zoospores are yellowish-green, multiflagellate, multinucleate and ovoid structures that have a small central vacuole. They are also referred to as compound zoospores.

Detailed explanation-4: -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.
