Multicellularity

Question 1

Multicellularity

Answer 1

Larger organisms don’t have larger cells they have more cells
-Growth due to increased cell size= Not sufficient as SA to V ratio is not reduced
-Growth due to increased # of cells= Sufficient as ratio is constant

Question 2

Specialized Cells

Answer 2

Cells specialized for different functions
-Principle of Complementarity- Function reflects structure and structure determines function

Question 3

Differentiation

Answer 3

Process by which cells become irreversibly specialized in structure and function

Question 4

Organization

Answer 4

Structural hierarchy that relies on the cooperation of specialized cells

Organisms, organ systems, organs, tissues, specialized cells
