Answer 1

Plants
Animals
Fungi
Protoctists

Question 2

Protoctists

Answer 2

Single celled
Some are pathogens
Examples: amoeba, chlorella, malaria

Question 3

Plants

Answer 3

Cellulose cell wall
Chloroplasts store carbs as starch/sucrose
Multicellular
Example: herbaceous legume, cereal

Question 4

Animals

Answer 4

No cell wall 
No chlorophyll - heterotrophic 
Stores carbs as glycogen 
Multicellular 
Nervous system for coordinationo

Question 5

Fungi

Answer 5

Absorb food from dead material
Cell wall made of chitin
Multicellular fungi are organised into a mycelium (made from hyphae)
Saprotrophic nutrition - secret enzymes into food then they absorb the digested organic products
Example: mushrooms, sac fungi, mucor

Question 6

What are pathogens

Answer 6

Disease causing viruses, bacteria, fungi or protoctists which can infect animals and plants

Answer 7

All are parasites
Not living organisms
They can only reproduce inside living cells
Have a protein coat and contain either DNA or RNA
Contains a membrane called an envelope

Question 8

Human diseases

Answer 8

Measles, mumps, polio, AIDS (caused by HIV virus)

Question 9

Plant diseases

Answer 9

Tobacco mosaic virus - causes discolouring of the leaves of tobacco plants by preventing the formation of chloroplasts

Question 10

Is bacteria prokaryotic

Answer 10

Yes

Question 11

Bacteria

Answer 11

No true nucleus 
Cell wall made of murine 
Slime capsule 
Large circular DNA molecule 
Flagella - tail 
Feed from other organism
