Being Principled…Looking At Organisms In new lab groups! At your lab station, look at the organism: 1) Identify why it is called living 2) What are 3 ways your group is able to classify each species? Ex. Dog, cat, fig tree, mushroom, algae, fish, Plants/animals Eyes/ no eyes Water/land Type of cells Cell wall/ no cell wall
