A euglena is a unicellular organism. Choose an everyday object, such as a car, to use as a model of this euglena. Explain how the parts of the object model how the euglena's cell parts help it stay alive.

Answer:

a car:

Flagellum  is a long thread-like structure that works as a navigator or a steering wheel in a car. The thin filament helps an euglena to move forward in any direction it desires.

Cell membrane is like the doors on a car. They regulate what goes in/out. The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.

The Nucleus is like the front seat of your car because the driver is in control of what the car does, goes, and what happens inside of the car.

Vacuoles is like the Trunk of your car because you store food, water and other wastes into your trunk, like were all the things go in the vacuoles.

The compression stroke in a car engine is like chloroplasts because it gas to fuel a car the same way chloroplasts convert solar energy in to chemical energy for a cell.

Mitochondrion is like the battery on a car. It gives the motor energy so it can run like the mitochondrion produces energy for the cell.

Eyespot is like a radio, because in some cars, radios pull power directly from the battery from the car battery, and this is why you will get the car radios on while the engine is off

Explanation:

The internal structures found in a typical photosynthetic Euglena are as follows:

Pellicle: A thin, flexible membrane that supports the plasma membrane and helps them to change shape

Plasma Membrane: The selectively permeable membrane that protects the inner content of the cell from the outside environment

Cytoplasm: A jelly-like substance distributed throughout the cell that contains all the cell organelles

Chloroplast: Contains the green pigment chlorophyll that helps them to produce food using sunlight by photosynthesis

Nucleus: A membrane-bound organelle that contains the genetic material, DNA. It also contains a distinct nucleolus that contains RNA and helps the cell to synthesize proteins

Mitochondria: The energy-producing organelle that forms ATP. All cellular activities such as movement and reproduction are performed using the mitochondrial energy source

Ribosomes: Consists of RNA and proteins, and are responsible for producing all cellular proteins

Golgi Apparatus: Manufactures, stores, and transports large molecules such as carbohydrates and proteins within the cell

Endoplasmic Reticulum: The extensive network of membranes that helps to package and transport proteins to different organelles. It is of two types: rough endoplasmic reticulum (RER) – containing ribosomes attached to it; and smooth endoplasmic reticulum (SER) – devoid of ribosomes

Lysosomes: Small membrane-bound organelles filled with hydrolytic enzymes that break down large molecules such as carbohydrates, fats, and proteins

Contractile Vacuole: It maintains the water and salt balance within the cell

Reservoir: The inward pocket present near the base of the flagella where contractile vacuole dispels excess water

Flagellum: A long whip-like structure attached externally to the cell body that helps in cell movement. An amoeba contains two flagella, a short one that does not protrude out of the cell, and a long one that helps in swimming

Eyespot: A region that is highly colored and contains red-colored carotenoid pigments that help in the detection of light. It is sometimes called a stigma

Photoreceptor: Also known as the paraflagellar body, it is the light-sensitive region located near the flagellum that helps to detect light. It also helps in their movement towards and away from light stimuli, a process known as phototaxis  

Paramylon: They are stored starch-like carbohydrate granules composed of glucose produced during photosynthesis. Paramylon enables the organism to survive in low-light conditions when photosynthesis is not possible by acting as the food reserve for the cell. When the paramylon is enclosed in a sheath of polysaccharide, it is called the paramylon sheath of pyrenoid.

The flagellum of euglena, can be compared to the wheels of a car, as they are responsible for the movement of both.

Euglena is a genus of single-celled flagellated algae that can occur either as free cells or in colony form.

Euglenophytes have the presence of flagella as their main characteristic. They have two flagella, one longer than the other. The smaller flagellum does not emerge from the cell. The larger one is mainly used for locomotion.

With this information we can conclude that euglena has flagella for locomotion just as cars have wheels for locomotion.
