In Plants & Animals

Cells

Every living thing consists of cells, from people to plants to bacteria everything that is living has cells. According to Google (2013) "The smallest structural and functional unit of an organism, which is typically microscopic and consists of cytoplasm and a nucleus enclosed in a membrane." Without a microscope cells are impossible to see because they range from one to one hundred micrometers. There are two primary cells the Eukaryotic and Prokaryotic. Eukaryotic cells being those of plants and animals and prokaryotic being those of bacteria. Because prokaryotic cells are bacteria they have been around since the beginning of Earth and are capable of surviving of much more harsh environments. Scientists have found that 95% of the cells found in the human body are bacteria an most of which are found in your digestive track.



Animal & Plant Cells

Living cells are divided into two categories Prokaryotic and Eukaryotic plants and animals have Eukaryotic cells. Plant and animals cells are very similar but there are still some differences for example animal cells have Centrioles and there cells can be all sorts of shapes while plant cells have no Centrioles and are almost always a boxy shape. Plant cells also have a central Vacoule a Cell Wall and Chloroplasts
