Animal vs. Plant cell Venn Diagram • Draw a double Venn diagram and compare and contrast animal vs plant cells including: • Cell membrane, cell wall, cytoskeleton, size and shape, vacuoles, ribosomes, nucleus, DNA, and so on. Animal vs Plant Venn Diagram *Centrioles *Small vacuoles Chemical and Physical Changes •Chemical Change – change that results in the production of another (new) substance •Signs of Chemical Changes Color change Bubbles (formation of gas) Temperature change Precipitate (formation of solid) Change in odor •Physical Change – change that does not result in the production of a new substance, a change in the size, shape or state of matter •Some physical changes can be reversed. For example, you can refreeze water into ice, but you cannot put your hair back together if you don’t like the cut. Chemical or Physical Change? Painting wood PHYSICAL Chemical or Physical Change?
