food & number of cells

called divisions.– Plants divided into 2 groups: vascular and

nonvascular• Animal Kingdom – 35 phylum – These phyla can be classified into 2 groups:

vertebrates and invertebrates

fewer organisms that have a lot in common as you move down the levels

Genus• Closely related organisms• The first word in an organism’s scientific name
