Euglena+-+MS

= Introduction = Imagine, you have a harmful bacteria in your body, and you have to get it out before the bad bacteria affect you. Euglena can help because it can eat the harmful bacteria. So, scientist want to use euglena in products because it has all the right nutrients that is needed in the human body. Euglena is a small organism in the protist Kingdom, which really is a kingdom of mostly unicellular cells like Euglena that do not fit into the other kingdoms. Euglena gracilis is just one of the many species of euglena. Euglena is very confusing to scientists, because they are a combination of a plant and animal cell. For instinct, they can make their own food like a plant, but can also eat other things, like an animal. We are focusing on these three main ideas, what are the unique structures of euglena, can euglena be beneficial to humans, and how does euglena move. = What is euglena? = So, now we ask what is euglena? Euglena are small organisms, and a euglena's body is only one cell. Euglena is also a single-cell microorganisms that have features of both plant and animal cells. There are approximately 150 species exist of euglena. Euglena can eat Green algae, Amoeba, Paramecium, Rotifer. They eat all those things while they can make there own food too.

= What are the unique structures euglena = There are many unique structures to euglena. In the article" [|Grolier Online] " explains that, o ne example is that they have a red eyespot or a stigma, that guides the cell toward the light. These two structures are responsible for light sensitivity. Another unique structure is the harnessing light, what it does, is that it traps sunlight and then uses the sunlight to make food. In addition to the many chloroplasts, there are reserves of carbohydrate (paramylon or paramylum) in the cell. They also have a large nucleus, that is located in the posterior half of the body. In the article "[|euglena]" it tell you about the color of euglena. The color of a euglena is green, but why is that? It's because euglena eats green algae. They keep the algae c hloroplasts inside their bodies and use it to make their own food. They also have a flagellum that they use to whip themselves through the water. = = = Can euglena be beneficial to humans? = So, now we get to the point where we wonder if euglena is beneficial to humans. In fact it can be beneficial to humans. Some reasons are that scientists know that euglena eats harmful bacteria, and so, according to the article" [|Euglena | The world's most interesting protist!] " they tell you that scientists want to use euglena for products because it has all of the nutrients that are needed in the human body. It is also good for humans because euglena can tell us if the is polluted, because it thrives in places where green algae is bulging. To have the green algae be there, is when there is a lot of nitrogen in the water which comes from waste. Lastly, to say, that there is no scientific evidence that Euglena is harmful to people. = How does euglena move = Now for the the Euglena to move into the light to create its own food, it uses its flagellum. The flagellum is a long tail like structure that allows it to move by waving back and forth pushing the protist forward. The base of the flagellum has a bend, and this makes it sweep around as it spins. The flagellum is what they use to move around. The Euglena has a Contractile vacuole, which prevents the cell from bursting by pumping all of the excess water out of the cell. Finally there is the pellicle which is a structure of microtubules. These pellicles cross each other and this causes Euglena to be flexible and strong. = media type="youtube" key="jl0TzaWUQWk" width="399" height="284" = = Conclusion = Overall, Euglena is a small organism in the protist Kingdom, Euglena can be confusing to scientists, because they are a combination of a plant and animal cell. For a example, they can make their own food like a plant, but can also eat other things, like an animal. We are focusing on these three main ideas, what is euglena, what are the unique structures of euglena, can euglena be beneficial to humans, and how does euglena move. Therefore, scientist want to use euglena in products because it has all the right nutrients that is needed in the human body. Lasty, to have eugena, is very important because it can help you with the nutrients that you need if you don't have enough. = References = = = = =
