A euglena is a unicellular organism. Explain how the euglena's cell parts help it stay alive. Write your response below

Explanation:

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.

what bodys are there orbiting?

essentially, one bacterial cell splits into two daugurer cells. bacterial offspring don't need or get care from their parents because they are in a sense their own parents. that said, some bacteria can and do depend on other bacteria especially in harsh environments such as bacterial microfilms in hot water tanks.
