Reproduction

the process of that produces more individuals of the same species

Sensitivity

detecting a change ın internal or external environment to be able to respond to it

Growth

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
