Cell ---> Tissue ----> Organ ---> Organ System ---> Animal The property where living things become more and more complex going from cellular level up to organ system!

A proposed explanation made on the basis of limited evidence as a starting point for further investigation.

Also known as a reduction atmosphere, is an atmospheric condition in which oxidation is prevented by removal of oxygen and other oxidising gases or vapours.

Combining nonliving substances.

Miller-Urey Apparatus

A device created to replicate the primeval conditions on earth and to produce chemicals that were essential for life to begin. It included a closed system, allowed for a mixture of gases to be pumped in, also boiling water to allow water vapour.

A large complex molecule, such as nucleic acids, proteins, carbohydrates, and lipids, with relatively large molecular weight.

Large ordered structure, enclosed by a membrane, that carries out some life activities, such as growth and division.

A bubble-like membranous structure that stores and transports cellular products, and digests metabolic wastes within the cell;

A double-stranded nucleic acid that contains the genetic information for cell growth, division, and function.

Abbreviation for ribonucleic acid: a nucleic acid that is generally single stranded and plays a role in transferring information from DNA to protein-forming system of the cell.

An RNA molecule that acts as an enzyme

The Great Oxygen Event. "GOE" The biologically induced appearance of free oxygen (o2) in earth's atmosphere.

An organism that contains all of its DNA in a non membrane enclosed region called a NUCLEOID. "Before Nucleus". Evolved before Eukaryote cells.

An organism that contains most of its DNA in a NUCLEUS, also bound by a double membrane. "True Nucleus"

The interior of a cell. In Eukaryotes it refers to the region between the nucleus and the membrane.

Smallest known cell. "Mycoplasms

Functions as the selective barrier that allows the passage of Oxygen, Nutrients and wastes to service the entire cell.
