Autotroph

• Organisms capable of producing their own food

• Organisms that consume other organisms for energy

• Organisms that decompose organic material

• Organisms that rely on sunlight for energy

Multicellular

• Organisms made up of multiple cells

• Single-celled organisms

• Organisms that can live in extreme environments

• Organisms that reproduce asexually

Variation

• Differences in behavioral or physical traits observed among individuals within a population of organisms

• A type of genetic mutation that occurs in a single organism

• The process by which organisms adapt to their environment over time

• A method of reproduction that involves two parent organisms

Cell

• The basic unit of structure and function in living organisms

• A type of tissue found in plants

• A small organelle within a larger cell

Cell theory

• All organisms are composed of one or more cells, all cells come from pre-existing cells, and cells are the basic unit of structure and function in organisms.

• All living organisms are made up of tissues and organs that function independently.

• Cells are only found in multicellular organisms and are not present in unicellular organisms.

• Cells can spontaneously generate from non-living matter.

Organism

Prokaryote

• An organism that can photosynthesize

• A type of virus that infects bacteria

Eukaryote

• A unicellular organism without a nucleus

• A multicellular organism that contains genetic material (DNA) and has a nucleus

• A type of virus that contains RNA

• A prokaryotic organism that lacks membrane-bound organelles

Unicellular

• Organisms that are made of one cell

• Organisms that are made of multiple cells

• Organisms that can live in extreme environments

• Organisms that reproduce sexually

Heterotroph

• Organisms that can make their own food using sunlight

• Organisms that cannot make their own food and depend on other organisms as their food source

• Organisms that produce energy through photosynthesis

• Organisms that are capable of living in extreme environments
