CH10 the five kingdoms Flashcards
1
Q
What are the five kingdoms
A
- prokaryote
- protoctista
- fungi
- plantae
- animalia
2
Q
Prokaryotae
A
- unicellular
- no nucleus or other membrane-bound organelles
- no visible feeding mechanism
3
Q
Protoctista
A
- mainly unicellular
- a nucleus and other membrane-bound organelles
- some have chloroplasts
- some are sessile but others move by cilia, flagella, or by amoeboid mechanisms
- nutrients are aquired by photosynthesis, ingestion of other organisms or both
4
Q
Fungi
A
- uni or multicellular
- a nucleus and other membrane-bound organelles and a cell wall mainly composed of chitin
- no chloroplasts or chlorophyll
- no mechanisms for locomotion
- most have a body or mycelium made of threads or hyphae
- nutrients aquired by absorption
- most store their food as glycogen
5
Q
Plantae
A
- multicellular
- a nucleus and other membrane-bound organelles including chloroplasts, and a cell wall mainly composed of cellulose
- all contain chlorophyll
- most do not move
- nutrients are aquired by photosynthesis
- store food as starch
6
Q
Animalia
A
- multicellular
- a nucleus and other membrane-bound organelles
- no chloroplasts
- move with the aid of cilia, flagella, or contractile proteins
- nutrients are aquired by ingestion
- food stored as glycogen
7
Q
A
8
Q
Why doe internal and external features change as an organism evolves
A
- dna determines proteins that are made, which in turn determines organisms characteristics
- in order for characteristics to change, dna must have changed
9
Q
What are the three domains
A
- eukarya
- bacteria
- archaea
10
Q
Eukarya
A
- have 80s ribosomes
- rna polymerase contains 12 proteins
11
Q
Archaea
A
- have 70s ribosomes
- rna polymerase contains between 8 and 10 proteins
12
Q
Bacteria
A
- have 70s ribosomes
- rna polymerase contains 5 proteins
13
Q
Archaebacteria
A
- bacteria living in extreme environments
14
Q
Eubacteria
A
- true bacteria
