Monerans, Viruses, and Protista

Host: an organism that a parasite feeds on Vocabulary Host: an organism that a parasite feeds on   Parasite: organism gets food by living in or on an organism

MONERA Unicellular (one cell) without a nucleus Microorganism (small)- organism that can only be seen under a microscope Structure: ___Flagella____ Flagella: used for movement such as propelling forward

Harmful bacteria cause sickness and food spoilage Destroyed by anti-biotics Helpful bacteria are used in environmental oil spills and fertilizer, digestion of food, and production of antibiotics (medicine used to kill harmful bacteria) Example: Yogurt and Cheese

Viruses Tiny particles that invade a host cell Cannot reproduce on their own, need other living cells Parasites: lives in or on a host cell **HARMFUL** Causes diseases such as the flu, stomach virus, cold, chicken pox, HIV(AIDS) Video

ANTIBIOTICS DO NOT help destroy the virus Vaccines: dead or weakened strain of a virus that causes an immune response(antibodies) *helps to prevent you from getting the disease* Video

Protists Unicellular (one cell) with a nucleus They usually live in water. Some protists move around, while others stay in one place Examples of protists include some algae, paramecium, and amoeba Video

Amoeba Amoeba moves with pseudopods Kingdom: Protist Unicellular or Multicellular Reproduce asexually (one parent) Animal like Heterotroph: must eat to gain energy Video

Paramecium Paramecium moves with cilia Kingdom: Protist Unicellular or Multicellular Reproduce asexually (one parent) Animal like Heterotroph: must eat to gain energy Video

Euglena Euglena moves with flagella Kingdom: Protist Unicellular or Multicellular Reproduce asexually(one parent) Animal like AND Plant Like Autotroph: can make its own food through the process of photosynthesis AND Heterotroph: must eat to gain energy Contains chloroplast to help with photosynthesis Video
