Euglena+-+CB

= Introduction =

You look into a little pond, and what do you find a little call that may lead to a cure of cancer. That cell isn't just a plant cell or just an animal cell, it is both. With its’ eyespot ( a sensory organ of lower animals, having a light-perceiving function.) it will locate light and use its’ chloroplast ( a plastid containing [|chlorophyll] .) to get nutrients. But say it wants a midnight snack and there is no light to be found, it might just kill a fish for a snack. This amazing cell is called the euglena a genus of green freshwater protozoans having a reddish eyespot and a single flagellum, found especially in stagnant waters) . (Deffinitions found on [|__http://dictionary.reference.com/__] )

= Important Parts of the Euglena =

The euglena is made up of many parts, and they each are very important. One interesting part is the flagellum ( a long, lash like appendage serving as an organ of locomotion), it moves the cell just like a propeller moves a helicopter. Another intriguing part of the euglena is the eyespot, it will locate light. An additional part of the euglena is the chloroplast, it turns light into nutrients just like a solar panel. The pellicle ( a thin skin or membrane; film; scum.) is the outer layer of the cell. One of the parts works like a refrigerator, it’s the contractile vacuole ( a membrane-enveloped cellular organelle, found in many microorganisms, that periodically expands, filling with water, and then contracts, expelling its contents to the cell exterior: thought to be important in maintaining hydrostatic equilibrium.) The nucleus is the brain of the cell ( a specialized, usually spherical mass of protoplasm encased in a double membrane, and found in most living eukaryotic cells,directing their growth, metabolism, and reproduction, and functioning in the transmission of genic characters.).

= Euglena Plant or Animal =

The euglena is a very special cell because it is autotroph (any organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy, as most plants and certain bacteria and protists) and heterotroph ( an organism requiring organic compounds for its principal source of food). It will use the eyespot to locate light and then use the chloroplast to turn light into energy through photosynthesis. And when there is no sunlight it will eat other cells.

= About the Euglena =

According to Microscopy ( [|__http://www.microscopy-uk.org.uk/index.html?http://www.microscopy-uk.org.uk/ponddip/euglena.html__] )The little euglena is about 25 - 100 µm big ( 1/10 of a millimetre). It finds euglena finds its home in freshwater ecosystems. According to National Oceanic and Atmospheric Administration ( [|__http://oceanservice.noaa.gov/podcast/sep09/mw093009transcript.html__] ) the euglena will kill fish in their ecosystems. What is really cool is that the toxin that they release can help cure certain types of cancer. The euglena can even kill animals that drink from the water.

= Conclusion =

Now that you know one thing in that pond would you still swim in it. You should the little 1/10 of a millimeter big euglena wont harm you. Th = References =
