PROTISTS, Euglena Screen Shot 2023-07-23 at 1.19.10 PM - Coggle Diagram

- - - - Uses:
        
        Used as a research model to study cell structure, movement and behaviour in freshwater ecosystems
        
        It is an environmental indicator - Presence of paramecium indicates a healthy ecosystem.
        
        Harmful Effect:
        Does not have any direct harmful effects on humans of the environment.
      - It has numerous hair-like structures called CILIA that cover its entire body. The CILIA beat rhythmically, propelling the organism through the water, and also helps it capture food.
      - FUN FACT: Has two nuclei:
        One nuclei (macronucleus) helps in regulating and controlling cell functions.
        Second Nuclei (micronucleus) is involved in reproduction.
    - - Has a long whip-like FLAGELLUM which enables it to execute movement in the host's bloodstream and tissues
      - Parasite
      - Uses:
        
        Used in research to study parasitism and the mechanisms of diseases like African Sleeping Sickness (Tryponosoma brucei)
        
        Harmful Effect:
        
        Trypanosoma brucei and Tryponosoma cruzi are parasites that cause human diseases such as African Sleeping Sickness and Chagas disease.
    - - Uses PSEUDOPODIA to capture food
      - Found in fresh-water habitats
      - Uses:
        
        Used in biological research to study cell biology and phagocytes
        
        Harmful Effects:
        
        Some amoeba like Naegleria fowleri are pathogenic. This amoeba is responsible for severe brain infection. It enters through the nasal passage.
