Unicellular | Made up of one cell, has to do all of life's functions by itself, it will always be by itself, ect. Examples: Bactiria |
Multicellular | Made up of one or more cells, Examples: Humans, dogs |
Cell Respiration | The process by which living organisms use oxygen to help break down food molecules to release energy |
Homeostasis | Maintain a stable internal environment: response to the environment |
Growth and repair | Changing throughout an organism’s life |
Multicellular facts | Must be made of more than one cell, they are more complex than unicellular, Cells can specialize to perform different life processes for the organism, each cell has its own job |
