- Eukaryotic cells (complex & large with specific organelles)
- Multicellular (plants are composed of MANY cells)
- Autotrophic (make their own food via photosynthesis)
- Other unique features: Cells have a thick cell wall, and green parts of plant contain chloroplasts
KINGDOM ANIMALIA (ANIMALS)
- Eukaryotic cells (complex & large with specific organelles)
- Multicellular (animals are composed of MANY cells)
- Heterotrophic (must ingest/eat other organism for energy)
KINGDOM FUNGI (FUNGUSES)
- Eukaryotic cells (complex & large with specific organelles)
- Most are multicellular: ex. mushroom
- Some are unicellular: ex. yeast
- Heterotrophic (most are saprotrophs: absorb nutrient from dead or living material)
KINGDOM PROTISTA (PROTISTS/PROTOZOANS)
- Eukaryotic cells (complex & large with specific organelles)
- Most are unicellular
- Some are multicellular
- Some are heterotrophic (must ingest/eat other organism for energy)
- Some are photosynthetic autotrophs
KINGDOM EUBACTERIA (BACTERIA)
- Prokaryotic cells (very simple & small in comparison, no specific organelles)
- Unicellular (the organism is just one cell)
- Can be heterotrophic or autotrophic (characteristic for classification conditions can vary greatly)
- Cell shape is a major characteristic for classification:
- Cocci-round or sphere shaped
- Baccili-rod shaped
- Spirlli-spiral shaped
KINGDOM ARCHAEBACTERIA (ANCIENT BACTERIA)
- Prokaryotic cells (very simple & small in comparison, no specific organelle)
- Unicellular (the organism is just one cell)
- Many are extremeophiles: live in & obtain energy in very extreme conditions where no other organism would survive
- These are the oldest known organisms & believed to be the first on this planet
