The Five Kingdoms

Question 1

List the features of Animalia (Group of Kingdom rank)

Answer 1

Eukaryotic​

No cell wall​

Multicellular​

A nucleus and other membrane bound organelles​

Heterotrophic (cannot produce its own food so, consumes other organisms for energy )​

Food stored as glycogen

E.g. (jellyfish, worms, sponges, fish, amphibia, reptiles, birds and mammals)

Question 2

List the features of Plants (Group of Kingdom rank)

Answer 2

Eukaryotic​

Multicellular​

Cellulose cell wall​

Use light to produce food by photosynthesis (autotrophic)​

Store food as starch​

E.g. (algae, ferns and mosses, conifers and flowering plants ​)

Question 3

List the features of Fungi (Group of Kingdom rank)

Answer 3

Eukaryotic​

Chitin cell walls​

Usually multicellular ( can by unicellular, yeast) or have mycelium.​

No chloroplasts​

Saprophytic feeders​ (live and feed on dead and decaying organisms)

Store food as glycogen​

E.g. (Moulds, mushrooms, yeast​)

Question 4

List the features of Prokaryotae (Group of Kingdom rank)

Answer 4

Prokaryotic​

Unicellular​

Cells have no nucleus (circular DNA)​

Absorb nutrients or produce them internally by photosynthesis

E.g. (Bacteria e.g. E. Coli, Staphylococcus Aureus, blue-green algae​)

Question 5

List the features of Protoctista​ (Group of Kingdom rank)

Answer 5

Eukaryotic​

Single cell organisms or a colony of single cells​

Some have chloroplasts​

Move using cilia/ flagellum/amoeboid mechanisms​

Nutrients acquired by photosynthesis ( autotrophic) or ingesting other organisms (heterotrophic) or both.

E.g. (Amoeba, Paramecium​, Protozoa​)

Question 6

How does artificial classification classify organisms

Answer 6

Based on observable characteristics

Question 7

How does natural classification classify organisms

Answer 7

Includes natural relationships, internal and external features​

Based on evolutionary relationships ​

Evidence used from DNA sequences and amino acid sequences​

Mutations in DNA, alter proteins and therefore characteristics​
