Classifying Organisms

  • Organisms are living systems composed of smaller parts working together to carry out the process of life.
  • Multicellular organism is an organism that is made up of more than one cell. Fungi is an organisms that usually nutrients from dead or decaying matter and cannot carry out nutrients.
  • Protists is an organism that is neither plant or animal , but shares many if the same characteristics of both usually unicellular but can be multicellular.
  • Bacteria is the most basic of all unicellular organism

Unicellular Organisms

Nutrition: Many unicellular organism live in bodies of water and must move around to find food.

paramecia: Are Unicellular organism that are found in aquatic environment.

Amoeba: The amoeba is another animal like protist that must move about to find food. The amoeba uses phogocytosis to feed an organism.

Movement: A change in the shape or figure of all part of an organism a character of all living things.

Locmotion: Movement takes an object from one place in its environment to another a characteristic of animals.
