Classification Flashcards
(19 cards)
What is the definition of the word ‘classification’?
Sorting organisms into groups, based on their characteristics.
What are the five kingdoms (in order)
Animalia, Plantae, Fungi, Protoctista and Prokaryotae
Which kingdoms are multicellular?
Animalia, Plantae and fungi
Which kingdoms are unicellular?
Protoctista and Prokaryotae
What does multicellular mean?
More than one cell.
What does unicellular mean?
Only contains one cell.
What type of eaters members of the group Animalia and what does it mean?
Herotrophic feeders (get their food by eating and digesting other organisms)
What type of eaters are members from the Plantae Kingdom and what goes this mean?
Autotrophic feeders (make their own food through photosynthesis)
What type of eaters are organisms in Fungi and what does it mean?
Saprophytic feeders (get the food from dead or decaying matter)
What type of cell structure does Animalia have?
- No cell walls
- Complex cell structure with nucleus
What type of cell structure does Plantae have?
- Cell wall made of cellulose (supports plant)
- Complex cell structure with nucleus
What type of cell structure does fungi have?
-Complex cell structure was nucleus
What type of cell structure does Protoctista have?
-Complex cell structure with nucleus
What cell structure does Prokaryotae have?
-Simple cell structure with no nucleus
Why is there no kingdom for virus?
- They are not living
- They are not made up of cells
- They can only exist inside ‘host’ cells (e.g. Inside a human cell)
What is the difference between a vertebrate and an invertebrate?
Vertebrates have a supporting rod through their bodies. Invertebrates don’t.
How are vertebrates organised into different classes?
- How they absorb oxygen
- How they reproduce
- How they regulate body temperature
What is the definition of species?
A group of organisms, that can interbreed to produce fertile offspring.
Why are some vertebrates hard to classify?
Variation exists, asexual reproduction, ring species and hybridisation in ducks.
