CHARACTERISTICS AND CLASSIFICATION OF LIVING ORGANISMS 1

Question 1

What does MRSGREN stand for?

Answer 1

Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition.

Question 2

Which characteristic(s) involve Carbon Dioxide

Answer 2

respiration and excretion.

Question 3

What is nutrition?

Answer 3

the process by which the body takes in and uses materials for energy, growth and/or development.

Question 4

What is reproduction?

Answer 4

the production of fertile offspring.

Question 5

What is the smallest classification group?

Answer 5

Species

Question 6

What is a species?

Answer 6

A group of organisms that can reproduce to make fertile offspring.

Question 7

What is the scientific way of naming organisms called?

Answer 7

The binomial system.

Question 8

How does the binomial system work?

Answer 8

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.

Question 9

What system do you use to find out the binomial of an organism?

Answer 9

Dichotomous key

Question 10

How does the Dichotomous key work?

Answer 10

It works by asking a question and then either giving you two species, two more questions, or one of each based on the answer

Question 11

name the mnemonic device used to remember the classifications of living organisms

Answer 11

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

Question 12

What’s the largest classification group

Answer 12

Kingdom

Question 13

How many kingdoms are there?
and
What are their names?

Answer 13

5 Kingdoms
1) Animal Kingdom
2) Plant Kingdom
3) Fungus
4) Protoctistans
5) Prokaryotes

Question 14

What type of cells do animals and plants have?

Answer 14

Eukaryote cells

Question 15

Which Kingdom(s) have Prokaryote cells

Answer 15

The Prokaryote Kingdom!

Question 16

What is the main difference between eukaryotic and prokaryotic cells?

Answer 16

Eukaryote cells have membrane-bound organelles while prokaryotes don’t

Question 17

Which Kingdom(s) doesn’t have a cell wall?

Answer 17

Only one, the animal kingdom!

Question 18

Which Kingdom(s) have multiple materials to form the cell wall based on the species?

Answer 18

Protoctistans and prokaryotes

Question 19

What is the main difference between Heterotrophs and Autotrophs?

Answer 19

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

Question 20

What material makes a cell wall in a fungi cell?

Answer 20

Chitin

Question 21

How are plants different from fungi in terms of mode of nutrition?

Answer 21

Plants are autotrophs using photosynthesis while fungi are heterotrophs by absorption

Question 22

How are protoctistans and prokaryotes similar in terms of mode of nutrition?

Answer 22

They can be either heterotrophic or autotrophic by photosynthesis depending on the species (NEVER BOTH)

Question 23

Which Kingdom(s) have to be multicellular?

Answer 23

The Animal and Plant Kingdoms

Question 24

Which kingdom(s) have to be unicellular?

Answer 24

Prokaryotes

Question 25

Are protoctistans unicellular or multicellular?

Answer 25

Mostly unicellular but some could be multicellular depending on the species
