Biology EOY Revision- Variation and Classification

Variation and Classification

• The 5 kingdoms- Prokaryotae, Protoctista, Fungi, Plantae, Animalia.
• The 5 vertibrate groups- mammals, birds, fish, reptiles, amhibians.
• All organisms show variation, both within and inbetween species.
• Genetic information is inherited
• Variation is caused by inherited and environmental factors.
• The Characteristics of the 5 kingdom groups-
• Animalia characteristics- multicelluar, no cell wall or chlorophyll.
• Plantae characteristics- mulitcelluar, have cell wall and chlorophyll
• Fungi characteristics- multicelluar, have cell walls but do not have chlorophyll.
• Protoctista characteristics- usually unicelluar, with a nucleus eg ameoba.
• Prokary characteristics- unicelluar, with no nucleus eg bacteria.
• Characteristics of the 5 vertibrate groups-
• Fish- the body of the fish is covered in scales and has fins attached to help it move through the water. Fish breathe using gills which take oxygen out of the water.
• Amphibians- The skin of amphibians is very thin and must always be kept wet because amphibians breathe through…
