All Living Things have NEEDS Materials-water, oxygen Energy-food, sun (plants) Living Space-somewhere to get materials and energy
Living Things have CHARACTERISITCS Organized-cells, tissues, organs, organ systems, organism Growth-to become larger Reproduce-create more, avoid extinction Environment, Respond-ability to change as the environment changes.
DO NOW October 3 How are living things organized? Why do living things need to reproduce? A brown chameleon moves into a tree and changes color to green. What characteristic of living things in this behavior?
The Cell Theory All living things are made up of one or more cells Cells carry out all basic life functions All cells come from other cells
Francisco Redi Believed in spontaneous generation-living things (bacteria) can come from non-living things. Why did he think this?
Louis Pasteur Disproved Redi s theory of spontaneous generation Developed the process of pasteurization Pasteur's Life
Exit Ticket How does the theory of spontaneous generation and the cell theory disagree?
