Euglena's Connection to Humans and Historical Background

Euglena's Life and Basic life Functions

Amoeba's live in water including lakes, ponds, streams, rivers, and puddles. Some amoeba's can live in animal bodies. Amoeba's shelter in Yellow Pond Lily's, common Duckweed, and Green Algae.

Euglena's food gathering and reproduction

Amoeba's is in the kingdom of Protists. It is is also in the phylum Protozoa and in the class Rhizopoda. Its scientific name is Amoeba because that is already a specific genus. Amoeba's only have one cell in their whole body. Amoeba is sometimes helpful in controlling algae in ponds, and lakes. They also provide small animals with food. Amoeba sometimes can make people ill when they get inside their bodies. An example of an Amoeba disease is a Brain eating Amoeba. This Amoeba is found in places such as warm lakes, ponds, and rock pits. They love warm places and can survive in water as hot as 113°F.

Amoeba's eat Green Algae, Paramecium, bacteria, Euglena, and tiny particles of dead plants. Amoeba's predators include Flatworm, Water fleas, Golden Shiner, and Euglena. Amoeba reproduces by binary fission, just like Euglena. This means that one Amoeba can split in half and make two identical new Amoebas.

Euglena has no negative affects on humans but it has many benefits. Euglena is a very effective organism in reducing Carbon Dioxide levels, it is even more effective at doing this then many plants. It also has many vital nutrients necessary in the human body. Euglena contain at least 800 species and most of them are green. Most of them are green because of the presence of chlorophyll A and B. Euglena is found in fresh water pools, ponds, and lakes. It's scientific name is Euglena. Euglena are unicellular microorganisms belonging to the Kingdom Protista and to the phylum Euglenozoa. Member of this phylum are mostly found in fresh water with some in salt. It belongs to the class Euglenoidea, members of this class are all found in fresh water, do photosynthesis or eat other organisms, and also have a tough outer coating known as a pellicle.

Euglena moves by a Flagellum, which is a long whip-like structure that acts like a motor. The Flagellum is located on the front end of the Euglena. To move, the Flagellum twits and pulls the cell through the water. The Flagellum is attached at a inward pocket called their Reservoir. Euglena also has an eye spot towards the front end that detects light, it can be found near the Reservoir. It also has a stiff Pellicle outside the Membrane, this helps keep it's shape. In the center is the Nucleus, the Nucleus contains the cells DNA and controls the cells activities. The inside of the cell contains a jelly-like fluid. Towards the back of the cell there is a star-like thing called the Contractile Vacuole that helps the cell remove extra water. With out it the cell would take in too much water and this would cause the cell to explode.

Euglena are combination of plants and animals . They eat like plants by using photosynthesis, and they swim and move. The Euglena use its flagellum to swim, it also has a red spot to spot light. The Euglena can split it self into two. A Euglena's body is only one cell so they are very small. If there are millions of Euglena together they form a mat on the surface of a pond. The mat looks slimy like Algae. Euglena can get in swimming pools if they aren't clean

Euglena makes most of it's food from light. When Euglena Gracilis doesn't have enough light to make it's own food it swims around and preys on other tiny organisms, such as amoeba and paramecium. Euglena predetors include baby fish, frogs, and many more.Euglena does asexual reproduction (reproduces on its own) by Binary Fission, which is the most common and simple reproduction. Binary Fission involves the process of Mitosis, which are organelles duplicating and the two sets separate to form two identical daughter cells. Even though Euglena contains characteristics of animals there have not been any record of sexual reproduction.

Brain Eating Amoeba

Amoeba's Structure

Sources

Inside of an Amoeba is a jelly-like fluid called Cytoplasm. Bits of food and other materials float around in the Protoplasm . The most important part of an Amoeba is the Pseudopod (pronounced "Sudopod"). The Pseudopod is used to help the Amoeba move and eat. To move, it stretches the Pseudopod and pulls itself. To eat, it stretches the Pseudopod and surrounds a piece of food and then pulls it into the rest of it's body. The Pseudopod is part of the Amoeba's body.
