Classification

How were organisms grouped back in the day (BC)

natural relationships, similarities and differences

what are the 5 kingdoms

1. Plantae- autotropic, multicellular eukaryotes, reproduction by spores

2. Animalia - heterotrophic, multicellular eukaryotes

3. Protisa- single-celled eukaryotes

4. Monera- bacteria prokaryotes

5. Fungi- single and multicellular osmotrophic eukaryotes with cell walls

What are the 3 domain system

1. Archaea- prokaryotes

2. Bacteria- single celled prokaryotes bacteria ( round, rod, spiral shaped)

3. Eukarya- single or multicellular organisms with distinct membrane around nucleus

What are the units of classification

1. Kingdom- Animalia

2. Phylum- Chordata

3. Class- Mammalia

4. Order- Carnivora

5. Family -Felidae

6. Genus- Felis

7. Species- Felis Serval

Characteristic of Monera

• Bacteria

• Simple, single-celled, prokaryotes

• Photosynthesis or Chemosynthesis and others are parasites

• Simple cell divison

Characteristic of Protista

• Amoeba

• Simple, single-celled, eukaryotes, sometimes joined together

• Autotrophic, or heterotrophic

• Asexual reproduction

Characteristic of Fungi

• Mushroom, yeast, mould

• multicellular, eukaryotes with cell walls made of chitin

• Saprotrophs or parasites

• Sexual and asexual reproduction by means of spores

Characteristic of Plantae

• trees

• complex multicellular eukaryotes with cell walls made of cellulose

• Photosynthesis

• Sexual by means of male and female gametes (sex cells) and asexual reproduction by means of spores

Characteristic of Animalia

• Fish, humans

• complex multicellular eukaryotes without cell walls

• heterotrophic

• Sexual reproduction in others by means of male and female gametes (sex cells) and asexual reproduction in some groups
