Scientists classify organisms by sorting them into groups based on                  they share. 

Animals are classified into these two general groups

                    are animals with a backbone, made up of bones called vertebrae , that run the length of their body. 

                      are animals that have NO backbone

Vertebrates can be sorted further into five groups: 

                     or organisms that make their own food, can also be classified into two general groups based on the way in which they transport water and nutrients through their structures. 

               plants contain tissue through which and nutrients (sugar) move 

                      plants have no              through which water and               move 

Some plants use seeds to reproduce (like apple trees)  and some others have spores (like ferns) 

Some plants make their seeds in cones  (like roses or orange trees), while other plants have their seeds in flowers (like pine trees)
