1. 5/6 Kingdoms of Life!
The five-kingdom system of classification for living organisms, including the prokaryotic Monera and the eukaryotic Protista, Fungi, Plantae and Animalia is complicated by the discovery of archaebacteria.

2. Living things have certain life processes in common
Living things have certain life processes in common. There are seven things that they need to do to count as being alive. The phrase MRS GREN is a way to remember them: M
Movement
All living things move, even plants R
Respiration
Getting energy from food S
Sensitivity
Detecting changes in the surroundings G
Growth
All living things grow
Reproduction
Making more living things of the same type E
Excretion
Getting rid of waste N
Nutrition
Taking in and using food

3. 3 Domains of Life
Archaea - These microbes are Prokaryotes, meaning that they have no cell nucleus or any other membrane-bound organelles in their cells, but are different to Bacteria
Bacteria – are also Prokaryotes were among the first life forms to appear on Earth, and are present in most of its habitats. 
Eukaryotes - is any organism whose cells contain a nucleus and other organelles enclosed within membranes.

4. 5 Kingdoms of Life
Living organisms are divided into five kingdoms: Prokaryotae, Protista, Fungi, Plantae, Animalia
Characteristics of living things - Living things are made of cells, obtain and use energy, grow and develop, reproduce, respond to their environment, adapt to their environment.
Prokaryotae (Monera) - Unicellular and Microscopic. Non- membrane bound (no nuclear membrane, no ER, no mitochondria). Cell wall made of murein. Examples: Bacteria, Cyanobacteria.

5. 5 Kingdoms of Life
Protista - Unicellular (mainly) Many live in aquatic environments. This is usually the kingdom including organisms which aren't animals, plants or fungi that don’t form tissues. Examples: Algae, slime molds and the malaria causing Plasmodium.
Fungi - Multicellular, Cell wall made of chitin. The members of this kingdom don't possess photosynthetic pigments and are therefore heterotrophic. Examples: Mushroom, Mold, Puffball

6. 5 Kingdoms of Life + Viruses
Plantae - Eukaryotic, Multicellular, Cell wall made of cellulose. Members of the plantae group contain photosynthetic pigment and gain their energy through it and are therefore autotrophic.
Animalia - Eukaryotic, Multicellular, Heterotrophic. The members of this kingdom can be split into two groups, vertebrates and invertebrates.
Viruses (not living) - Acellular structures composed of nucleic acid enclosed by a protein coat. Not classified as living.
