1. Characteristics of Each Kingdom in Domain Eukarya:
- Protista: Mostly unicellular, some multicellular; can be autotrophs or heterotrophs; live in moist environments; some have cell walls.
- Fungi: Mostly multicellular (except yeasts); heterotrophs; absorb nutrients; have cell walls made of chitin; reproduce by spores.
- Plantae: Multicellular; autotrophs through photosynthesis; have cell walls made of cellulose; mostly sessile.
- Animalia: Multicellular; heterotrophs; lack cell walls; mostly motile at some stage in life.
2. Taxonomic Examples for Each Kingdom:

3. Multicellular vs. Unicellular Organisms:
A multicellular organism is made of many cells that work together. A unicellular organism is made of only one cell. The difference is in the number of cells and how they function. Multicellular organisms have specialized cells, while unicellular ones perform all life functions in one cell.
4. Heterotroph vs. Autotroph:
A heterotroph obtains energy by consuming other organisms. An autotroph produces its own food, usually through photosynthesis or chemosynthesis.
5. Prokaryote vs. Eukaryote:
Prokaryotes lack a nucleus and membrane-bound organelles. Eukaryotes have a nucleus and membrane-bound organelles.
6. Sessile vs. Motile; Bacterial Shapes:
Sessile organisms do not move. Motile organisms can move independently. Bacteria are commonly coccus (spherical), bacillus (rod-shaped), or spirillum (spiral-shaped).
7. Bacterial Arrangements:
Bacteria can be arranged as single cells, pairs (diplo), chains (strepto), clusters (staphylo), or tetrads (groups of four).
8. Scientific Names of Streptococcal Species:
- Streptococcus pyogenes
- Streptococcus pneumoniae
- Streptococcus mutans
