Is Scenedesmus autotrophic or heterotrophic?
Scenedesmus is known to have high biomass productivity among green algae, and has been actively researched for its use for bio-diesel production. Its heterotrophic production of biomass and lipid in optimized conditions is reported to have higher efficiency than its autotrophic production.
Is Scenedesmus motile?
Scenedesmus quadricauda, a spine-bearing species, (Fig. 1) is able to produce motile, cells (Fig.
What can S Obliquus be used for?
The microalga Scenedesmus obliquus has been used in postoperative recovery, assisting in coagulation of the skin surface. The extracts of the diatom Asterionella notata have an antifungal and antiviral activity. Toxic algae have been used as a depressant vessel, similar to tetrodotoxin found in fish (Richmond, 1990).
Is scenedesmus unicellular or multicellular?
Scenedesmus is a small, nonmotile colonial green alga consisting of cells aligned in a flat plate. The colonies most often have two or four cells, but may have 8, 16, or rarely 32 and are occasionally unicellular.
What phylum is scenedesmus?
Green algaeScenedesmus / Phylum
What was the source of carbon for the scenedesmus cells?
The present study three different micro algal culture were used from that Scenedesmus quadricauda possess better production of PUFA content under UV-B treatment using Sodium bicarbonate as a sole inorganic carbon source.
Why do scenedesmus colonies consist of 4/8 or 16 cells?
These even numbered colonies are due to its reproduction. Since they are very small, they are vulnerable to grazers. To defend against grazers, they form colonies for additional protection other than their spines.
Why is scenedesmus Colonial?
Scenedesmus. for higher trophic levels. The spines and bristles make the colonies more buoyant and allow them to uptake the light and nutrients that are more abundant near the surface, and may deter predation by herbivores.
How is scenedesmus Obliquus classified?
Scenedesmus obliquus is a green algae species of the genus Scenedesmus….
| Scenedesmus obliquus | |
|---|---|
| Division: | Chlorophyta |
| Class: | Chlorophyceae |
| Order: | Sphaeropleales |
| Family: | Scenedesmaceae |
Is s Obliquus motile?
obliquus belongs to the green algal class of the Chlorophyceae and to the order Sphaeropleales. Vegetative cells of S. obliquus are non-motile and often occur in coenobia (microcolonies) of four cells that are released from a mother cell.
How is the life function of nutrition carried out by scenedesmus?
Nutrition – the scenedesmus contains chloroplasts which contain chlorophyll. As a result, this organism can makes its own food through photosynthesis (it is an autotroph). Response – the scenedesmus often lives in colony with other scenedesmus when there are a lot of predators.
