a kingdom of complex, multicellular oragnisms that are usually green, haveb cell walls, cannot move around, and use the sun's energy to make sugar by photosynhesis | plantae |
a kingdom of nongreen, eukaryotic organisms that do not move, reproduce by spores, and get food from their surroundings by breaking down substances and absorbing the nutrients | fungi |
a kingdom made up of bacteria that live in extreme environments | archaebacteria |
they are found where other living things cannot survive | archaebacteria |
they can live in soil,water, or in the human body | eubacteria |

osmosis is important to cells because | cells are filled with fluids that are made mostly of water |
one type of fermantation in muscle cells produces | lactic acid |
photosynthesis allows | a plant to produce food |
when water diffuses into or out of a cell it is called | osmosis |
most complex organisms obtain energy through | cellular respiration |
what gas is released during cellular respiration? | carbon dioxide |
what do all organisms need to get rid of in order to live? | wastes |
osmosis benefits plant cells by bringing in | water |
