Cell Structure and Diversity

Question 1

Unity in Diversity

Answer 1

Unity found in shared features
* Divergence - similar base structure but adapted to their environments
* Convergence - not having a similar base structure but having similar similar pressures

Common ancestor (unity) but differences due to SPs (Diversity)

genus and name specific to species eg Homo Sapiens

carries out photosynthesis to produce food, autotrophs

Question 8

Fungi

absorbs nutrients from other deaad organisms, saprophyte

Question 9

Animalia

Answer 9

Multicellular Eukaryotes

Question 10

Protists

Answer 10

Mostly unicellular, some multicellular, some protists more related to P,A and F than other protists

Question 11

Natural selection

Answer 11

SPs, changes in allele frequency, accumulated changes over time, descent with modifications, selects the best trait for survival
