CHARACTERISTICS AND CLASSIFICATION OF LIVING ORGANISMS 1 Flashcards
(30 cards)
What does MRSGREN stand for?
Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition.
Which characteristic(s) involve Carbon Dioxide
respiration and excretion.
What is nutrition?
the process by which the body takes in and uses materials for energy, growth and/or development.
What is reproduction?
the production of fertile offspring.
What is the smallest classification group?
Species
What is a species?
A group of organisms that can reproduce to make fertile offspring.
What is the scientific way of naming organisms called?
The binomial system.
How does the binomial system work?
The binomial system is a two-word name, the genus is always written in capital letters. The second name tells us the species the organism belongs to.
Extra: When printed they are always in italics, when writing you have to underline the binomial.
What system do you use to find out the binomial of an organism?
Dichotomous key
How does the Dichotomous key work?
It works by asking a question and then either giving you two species, two more questions, or one of each based on the answer
name the mnemonic device used to remember the classifications of living organisms
Dear - Domain (probably not needed)
King (Keep) - Kingdom (largest we need to know)
Philip (Ponds) - Phylum
Came (Clean) - Class
Over (or)- Order
For (Frogs) - Family
Good (get) - Genus
Soup (Sad) - Species
What’s the largest classification group
Kingdom
How many kingdoms are there?
and
What are their names?
5 Kingdoms
1) Animal Kingdom
2) Plant Kingdom
3) Fungus
4) Protoctistans
5) Prokaryotes
What type of cells do animals and plants have?
Eukaryote cells
Which Kingdom(s) have Prokaryote cells
The Prokaryote Kingdom!
What is the main difference between eukaryotic and prokaryotic cells?
Eukaryote cells have membrane-bound organelles while prokaryotes don’t
Which Kingdom(s) doesn’t have a cell wall?
Only one, the animal kingdom!
Which Kingdom(s) have multiple materials to form the cell wall based on the species?
Protoctistans and prokaryotes
What is the main difference between Heterotrophs and Autotrophs?
Heterotrophs can’t produce their own food and resort to consuming nutrients from other species while autotrophs have different methods of creating their own food
What material makes a cell wall in a fungi cell?
Chitin
How are plants different from fungi in terms of mode of nutrition?
Plants are autotrophs using photosynthesis while fungi are heterotrophs by absorption
How are protoctistans and prokaryotes similar in terms of mode of nutrition?
They can be either heterotrophic or autotrophic by photosynthesis depending on the species (NEVER BOTH)
Which Kingdom(s) have to be multicellular?
The Animal and Plant Kingdoms
Which kingdom(s) have to be unicellular?
Prokaryotes
