Classification Flashcards
How do we classify species?
Using the five kingdoms. These are:
- Animal
- Plant
- Fungi
- Single celled organisms
- Bacteria
What is a distinction we can make between species related to backbones?
Vertibrates and invertebrates
How can we sort the plant kingdom?
Into flowering plants and non flowering plants
How do flowering plants reproduce?
They produce pollen which fertilises the eggs
How do non flowering plants reproduce?
Using spores
How do we write species?
Kingdom Phylum Class Order Family Genus Species
What is the binomial system?
The system we use to name an organism
What does the binomial system involve?
Using the organism’s genus and species to give it its name
What is a genus?
A kind of wider grouping of species: for example both dogs and wolves are in the canis genus
How can we abbreviate the binomial classification?
By giving the genus as only its first initial, for example P. Tigris
What is the difference between a morphological and behavorial adaptation?
Morphological adaptations are physical and behavorial relate to actions
How and why do we use quadrats to measure a population?
Because they allow scientists to randomize a sample fairly. They are simply laid out on a randomly generated patch of ground and the items in it counted
What resources do organisms need?
- Water
- Shelter
- Food
- Light
- Breathable air
- Mates
Why do populations vary?
Because of competition, predation, disease and pollution
When is the quadrat method not successful?
When estimating the population of an animal species
