Classification

Putting things into groups

Autotrophic

Organisms that use inorganic substances to produce organic nutrients

characteristics of kingdom animal

• Multicellular: Organisms in the kingdom Animalia are made up of multiple cells.

• Heterotrophic: Animals obtain their energy by consuming other organisms.

• Eukaryotic: Animal cells have a nucleus

• Lack cell walls: Unlike plants and fungi, animals do not have cell walls.

• Lack chlorophyll

Heterotrophic

Organisms that obtain nutrients by feeding on other living things

Monocotyledons

• Single cotyledon

• Parallel veins

• Floral parts in multiples of 3

• Vascular bundle scattered throughout stem

• Fibrous roots

Dicotlyedonous

• Two cotyledons

• Branched veins

• Floral parts are in multiples of 4/5

• Vascular bundle arranged in a ring

• Taproot

Advantages of of using DNA analysis to classify living organisms

• Accurate

• Easy/quick/cheap/efficient

• Allows large scale of identification

• Only trance samples are required
