No visible feeding mechanism. Nutrients absorbed through cell wall or produced by photosynthesis

Question 2

Question 3

Question 4

Nucleus and other membrane-bound organelles
Cell wall made of cellulose
Multicellular
Autotrophic

Question 5

Fungi

Answer 5

Eukaryotes
Nucleus and other membrane-bound organelles
Cell wall made of chitin
Multi OR Unicellular. Made of Hyphae
Saprophytic

Question 6

Differences between a classification system based on domains and one based on kingdoms

Answer 6

-> 3 domains VS 5 kingdoms
-> Domains: bacteria, archaebacteria, eukaryotes
-> Kingdoms: prokaryotes, protoctists, fungi, plants, animals
-> Kingdoms have eukaryotes separate VS Domain have eukaryotes together
-> Kingdoms have prokaryotes together VS Domain have prokaryotes separate
-> Domain classification based on RNA polymerase

Question 7

Name the 3 sources of evidence to help scientists classify organisms

Answer 7

Fossil
Molecular
Embryological
