Euglena Cell Diagram
Euglena Cell Diagram: Euglena is a genus of unicellular flagellate protists. There are many Euglena species which live both in fresh and salt waters. The most used Euglena species for scientific purposes is called Euglena gracilis. This unicellular flagelate includes chloroplasts in the body of the cell, being able to feed by autothrophy like plants, but also like animals, heterothrophically. As Euglena has both features from animals and plants, it was very difficult to be classified at the beginning. It is composed by a red eyespot, an organelle with carotenoid pigment granules. It does not have a wall cell, but a pelicle made up of a protein layer and microtubules. These important features make Euglena be very flexible and contractile. When there is not enough moisture, Euglena forms a wall around it and then lies dormant until the environment will get back to normal.
After being seen under the microscope, it was possible to conceive a cell diagram. A cell diagram can be different, depending on each species of Euglena. In time, better descriptions were given and people had the opportunity to see the new discoveries through a cell diagram. Several things were added to an Euglena cell diagram throughout time as new things were discovered.
Euglena cell diagram is different depending also by its colors, components and the way it feeds. There are many types of Euglena cell diagram taking into consideration also the species. Scientists did a lot of research to discover new things about Euglena and each new thing was added into a cell diagram. Euglenas are considered mixothrops: heterothrops in the dark and autothrops in the sunlight. Although it does not have cell walls, there are pellicles formed from protein bands which lie beneath the plasma membrane of Euglena. It reproduces asexually by fission and life spans are different for each group. The cell diagram shows the main components of it such as flagellum, which is important for mobility, photoreceptor, contractile vacuole, nucleolus, nucleus, stigma or eyespot, polysaccharides and chloroplast.
