Question

In euglena the protein rich layer is called..........

Answer 1

In euflena the protein rich layer is called pellicle.

Additional information :

✴ Euglenoids :

• Euglenoids occur in freshwater habitats and damp soils.
• Instead of a cell wall, they have a protein rich layer called pellicle which makes their body flexible.
• Though they are photosynthetic in the presence of sunlight, when deprived of sunlight they behaves like heterotrophs.
• Such a mod of nutrition is called as mixotrophic nutrition.
• Examples : Euglena, Phacus, Eutreptia.

▶ Kingdom Protista :

• All unicellular eukaryotic organisms are placed under protista, bur the boundaries of this kingdom are not well defined.
• It acts as a connecting link b/w the prokaryotic kingdom Monera and the complex multicellular kingdoms - Fungi, Plantae and Animalia.
• The kingdom Protista includes Chrysophytes, Dinoflagellates, Euglenoids, Slime moulds and Protozoans.

Answer 2

Answer:-

In Euglena the protein rich layer is called Pellicle.

Explanation:-

pellicle is a thin film of tissue, protein or other component with a wide range of roles and applications. It occurs naturally within organisms and on tooth enamel. It is also used in gastronomy and photography to coat or protect an object or surface.The pellicle has a tendency to incur stains, particularly in the areas that are inaccessible to toothbrushing,so this is protein rich later in Euglena.
