Kingdoms

There are 5 kingdoms:

  • Prokaryota
  • Protoctista
  • Fungi
  • Plantae
  • Animalia

Prokaryota:

- Unicellular
- Prokaryotic
- Cell wall= Plysaccharide + amino acid (Non-cellulose)
- Autotrophic or heterotrophic

Protoctista:

- Most forms are unicellular
- Eukaryotic
- Cell wall is present in some forms and varies
- Photosynthetic/Heterotrophic or a combination 
- Chloroplasts are present in some forms
- Contains Mitochondria
- Contains histone proteins associated with DNA

Fungi:

- Multicellular (except yeast=unicellular)
- Eukaryotic
- Cell wall= Chitin + other non-cellulose polysaccharides
- Its method of nutrition is external digestion using enzymes, absorbtion of soluble products, saprotrophic.
- Contains Mitochondria
- Contains histone proteins associated with DNA


Plantae:

- Multicellular
- Eukaryotic
- Cell wall= Cellulose + other polysaccharides 
- Photosynthetic (using chlorophyll a + chlorophyll b)
- Contains Chloroplasts
- Contains Mitochondria
- Contains histone proteins associated with DNA


Animalia:

- Multicellular
- Eukaryotic
- No cell wall
- Heterotrophic (ingestion)
- Contains Mitochondria
- Contains histone proteins associated with DNA
