3
Q
Eukaryotes
A
Animals, plants, fungi and protoctis
4
Q
Prokaryotes
A
Bacteria
5
Q
Animals
A
- ex: Bees
- Multicellular
- No cell wall
- No chloroplast
- Consumers (feed on other living
organisms) - Carbohydrates as glycogen
6
Q
Plants
A
- ex: onion
- multicellular
- cell wall made of cellulose
- Chloroplasts for photosynthesis
- Producers
- Carbohydrates as sucrose or starch
7
Q
Fungi
A
- ex: starch
- multicellular or unicellular
- cell wall made of chitin
- no chloroplasts
- saprophytic nutrition (live off of
decaying organisms) - sometimes parasites
- carbohydrates as glycogen
8
Q
Protoctis
A
- ex: amoeba
- multicellular or unicellular
- some have cell walls
- some have chloroplasts
- Either consumers or producers
9
Q
Bacteria
A
- ex: salmonella
- unicellular
- cell wall not cellulose
- no nucleus - circular chromosomes of
DNA - no membrane-bound organelles
10
Q
What is a pathogen?
A
A microscopic organism that causes a disease to another organism
11
Q
What organisms can be pathogens?
A
- fungi
- protoctis
- bacteria
- viruses
12
Q
Describe the levels of organisation of multicellular organisms
A
- cells are specialised to carry out
specific functions - cells form tissues
- tissues form organs
- organs form organ systems
13
Q
What is an organelle?
A
a component of a cell that carries out a specific task
14
Q
What is a cell?
A
The building blocks of organisms
15
Q
What are tissues?
A
a group of cells of similar structures that carry out a specific function
16
Q
What is an organ?
A
Tissues grouped together to carry out a specific function
17
Q
What is an organ system?
A
A group of organs that carry our a specific function
