What are the 5 kingdoms?

- Prokaryotae (bacteria)
- Protoctista (unicellular eukaryotes)
- Fungi (yeast, moulds and mushrooms)
- Plantae (plants)
- Animalia (animals)

Organisms were originally classified into these kingdoms based in similarities in their observable features.



- Unicellular
- No nucleus or other membrane bound organelles - ring of DNA
- No visible feeding mechanism - nutrients are absorbed through cell wall or produced internally



- Mainly unicellular
- Nucleus and other membrane bound organelles
- Some have chloroplast
- Some are sessile (fixed in one place), but others move by cilia, flagella, or by amoeboid mechanisms.
- Nutrients acquired by photosynthesis (autotrophic feeders), ingestion of other organisms (heterotrophic feeders), or both



- Unicellular or multicellular
- Nucleus and other membrane bound organelles and cell wall mainly made of chitin
- No chloroplast
- No mechanisms for locomotion (ability to move places)
- Most have a body of mycelium made of threads/hyphae
- Saprophytic feeders - acquire nutrients by absorbing decaying material.
- Store food as glycogen



- Multicellular
- A nucleus and other membrane-bound organelles like chloroplasts and cell wall made of cellulose
- Contains chlorophyll
- Most don't move, some gametes move using cilia or flagella
- Autotrophic - acquire nutrients by photosynthesis.
- Store food as starch



- Multicellular
- Nucleus and other membrane bound organelles, no cell walls
- No chloroplasts
- Move with aid of cilia, flagella, or contractile proteins, sometimes in the form of muscular organs.
- Heterotrophic feeders as nutrients acquired by ingestion
- Food stored as glycogen
