The five kingdoms of The five kingdoms of organismsorganisms
• Prokaryotes• Protoctists• Fungi • Plants• animals
ProkaryotesProkaryotes
• Prokaryotes include bacteria and blue-greeb algae (also known as cyanobacteria)
• They are very tiny and can only be seen with the high power of a light microscope.
Prokaryotes characteristicsProkaryotes characteristics
• They consist of a single cellsingle cell but do not not have any true nucleustrue nucleus ,mitochondia or chloroplasts.
• They exist in air,water,soil or inside other organisms.
ExampleExample
• Some of them cause diseases.
• E.G.Cholera , meningitis and tetanus .
• bacteria
ProtoctistProtoctist
• Protoctists are usually tiny and can be seen with the low powder of a light microscope.
• ProtoctistProtoctist
Protoctists characteristicsProtoctists characteristics
• Most of them consist of a single cellsingle cell with a true nucleus but some are multicellumulticellularlar.
• Some are plant-like plant-like and some are animal-likanimal-likee.
ExampleExample
• Examples include Amoeba , Paramecium , trypanosoma ,algae , slime moulds.
• Amoeca
FungiFungi Characteristics• Fungi are made up of a single cell or thread-like
structures called hyphae, which may be interwoven to form mushroom-like structures.
• Like plants, they have cell wall and do not move . But unlike plants , they have no chlorophyll to make their own food and do not have any roots , stems or leaves
• They are usually saprophytic or parastic and live on soil or inside other organisms, especially plants.
ExamplesExamples
• Examples include bread mould , Penicillium, yeast and mushtoom.
• YEAST
Classification of AnimalsClassification of Animals
•Vertebrates
•Invertebrates
VertebratesVertebrates
• Vertebrates are animals with a backbone.
The backbone is a long hard structure running along the back of these animals and is made up of many small bones called vertebre.It is also called a vertebral column.
Vertebrates featuresVertebrates features
• Some of them---
fish :
They bodies are covered by slimy scales.
They have fins for balance and movement.
They bodies are streamlined to aid movement.
They breathe with gills.
featuresfeatures
Amphibians :
They have wet , slimy skins but no scales.
They have four limbs when they are adult.
featuresfeatures
• Reptiles :
• They have skin covered by hard , dry scales.
• They breathe with lungs.
featuresfeatures
• Birds :• They have feathers
on their bodies and dry scales on their legs.
• Most can fly with wings but some cannot.
• They breathe with lungs.
InvertebratesInvertebrates
• Invertebrates are animals without without any backboneany backbone. Most of them are small. The following are some examples of invertebrates.
ExamplesExamples
• jellyfish : it lives in the sea.
• Freshwater flatworm: It lives in ponds and streams.
• Earthworm : It has a tube-like body with segments.
Classification of plantsClassification of plants
•Flowering plants
•Non-flowering plants
Flowering plants
• Flowering plants are divded into momocotyledonous plantsmomocotyledonous plants and dicotyledonous plantsdicotyledonous plants , usually abbreviated to monocots or monocotyledons , and dicots or dicotyledons respectively.
Monocotyledonous plantsMonocotyledonous plants
• They have only one seed leaf in the seeds.
• Their leaves usually have parallel veinsparallel veins.
• They are mostly herbs.
Dicotyledonous plantsDicotyledonous plants
• They have two seed ltwo seed leaveseaves in the seeds.
• Their leaves habe a nnetwork of veinsetwork of veins.
• They can be trees, shrubs and herbs.
Non-flowering plantsNon-flowering plants
• Non-floweringplants are divded into
mosses, ferns and gymnosperms.
mosses
• They are small plants with simple stems and leaves , but no roots.
• They have chorolhyll but no vascular tissue.
Ferns• They are small pla
nts with true roots ,true roots , stems and leaves. stems and leaves.
• They have large leaves called fronds . The leaflets on either sides are called the pinnae.
gymnosperms
• They are large plants with roots , stems, leaves and vascular tissue.
• Most of them have needle-shaped leaves.
