Characteristics of Each Kingdom

Comparing the five kingdoms of life based on cell type, structure, and nutrition

CAPS Grade 10 Life Sciences

In this section, you compare the five kingdoms—Monera, Protista, Fungi, Plantae, and Animalia—using the features exam questions usually test first: cell type, number of cells, cell walls, and nutrition. If you can compare those four features clearly, classifying unfamiliar organisms becomes much easier.

Kingdom Comparison Table

Use this table the way you would in class: compare one feature at a time and notice which kingdoms are similar and where they differ.

Kingdom Cell Type Cell Number Cell Wall Nutrition
Monera Prokaryotic Unicellular Present (peptidoglycan) Mostly heterotrophic
Protista Eukaryotic Mostly unicellular Present in some Autotrophic or heterotrophic
Fungi Eukaryotic Mostly multicellular Present (chitin) Saprophytic heterotrophs
Plantae Eukaryotic Multicellular Present (cellulose) Autotrophic (photosynthesis)
Animalia Eukaryotic Multicellular Absent Holozoic heterotrophs

Quick Check: Table Comprehension

1. Which kingdom has cell walls made of peptidoglycan?

Kingdom Details

Use these cards as a quick study guide when you need to revise examples and defining features for each kingdom.

Monera

Bacteria

Cell Type: Prokaryotic (no true nucleus)
Cell Number: Unicellular
Cell Wall: Present (peptidoglycan)
Nutrition: Mostly heterotrophic, some autotrophic
Examples: Bacteria, Cyanobacteria

Protista

Amoeba, Algae, Slime Moulds

Cell Type: Eukaryotic (has true nucleus)
Cell Number: Mostly unicellular
Cell Wall: Present in some, absent in others
Nutrition: Autotrophic or heterotrophic
Examples: Amoeba, Algae, Paramecium

Fungi

Mushrooms, Yeast, Moulds

Cell Type: Eukaryotic
Cell Number: Mostly multicellular
Cell Wall: Present (chitin)
Nutrition: Saprophytic heterotrophs
Examples: Mushrooms, Yeast, Moulds

Plantae

Mosses, Ferns, Conifers, Flowering Plants

Cell Type: Eukaryotic
Cell Number: Multicellular
Cell Wall: Present (cellulose)
Nutrition: Autotrophic (photosynthesis)
Examples: Mosses, Ferns, Trees, Flowers

Animalia

Invertebrates and Vertebrates

Cell Type: Eukaryotic
Cell Number: Multicellular
Cell Wall: Absent (only cell membrane)
Nutrition: Holozoic heterotrophs
Examples: Insects, Fish, Birds, Mammals

2. Which kingdom has yeast as a notable unicellular exception?

Common Classification Checks

These statements focus on the mistakes learners often make when comparing kingdoms.

1. All bacteria are harmful pathogens.
2. Fungi have cell walls made of chitin.
3. Animalia cells have cell walls made of cellulose.
4. Protista includes both autotrophic and heterotrophic organisms.

Study Tip

For the exam, practice using a Dichotomous Key to identify organisms. Focus on memorizing the key characteristics: Monera (prokaryotic), Fungi (chitin), Plantae (cellulose), Animalia (no cell wall), and Protista (diverse group).
