2Scientists Start Classifying Things by… LivingNon - Living
3But there are so many living things… We must classify them more…
4Classification System Scientists start by breaking plants/animals into kingdoms.Scientist continue to sort these groups into even smaller groups.Each time they sort, they use the organism’s features to decide whether or not the organism belongs to the group.The largest classification group would be the “kingdom”
5Scientists classify all living things into six major categories called kingdoms. An organism may be classified according to the number of cells and cell parts it has, where it lives, and how it obtains food.
6Example how Scientists organize the Animal Kingdom All animals belong to the same kingdom.Scientists use the smallest two groups to name organisms.A genus is a group of closely related living things.A species is a group of similar organisms that can mate produce offspring.
7Scientists divide the animal kingdom into two main groups.
44After sorting vascular and non vascular… We sort those by:How they reproduce:Seeds or Spores
45Example how Scientists organize the Plant Kingdom Scientists sort plants in a variety of ways, based on how they transport water and nutrients or how they reproduce.Vascular plants have tubelike structures that transport water and nutrients within the plant. Ex: Bamboo & TreesNonvascular plants grow low to the grown and can pass water and nutrients only from one cell to the next. Ex: Moss & Hornworts
46Classifying Plants by flowers, seeds, and spores Flowering plants and cone-bearing plants reproduce by producing seeds.Ferns and mosses reproduce by producing spores.
