How we organize living things

eukaryote

• An organism whose cells contain a nucleus and other organelles enclosed within membranes.

• A single-celled organism without a nucleus.

• An organism that can photosynthesize and produce its own food.

• A type of bacteria that lacks a cell wall.

prokaryote

• An organism whose cells lack a nucleus and other membrane-bound organelles.

• A type of cell that contains a nucleus and membrane-bound organelles.

• An organism that can perform photosynthesis.

• A multicellular organism with complex tissues.

multicellular

• An organism made up of multiple cells that work together.

• A single-celled organism that can survive independently.

• An organism that consists of only one type of cell.

• An organism that can reproduce asexually.

unicellular

• An organism made up of a single cell.

• An organism made up of multiple cells.

• A type of virus that can infect single cells.

• An organism that can live in extreme environments.

autotroph

• An organism that produces its own food, typically through photosynthesis.

• An organism that consumes other organisms for energy.

• An organism that decomposes organic material.

• An organism that relies on external sources for food.

heterotroph

• An organism that produces its own food through photosynthesis.

• An organism that obtains its food by consuming other organisms.

• An organism that can survive without any food source.

• An organism that primarily feeds on decomposed matter.
