A2.2.14 (HL)—Evolution of multicellularity Topic Practice
A2.2.14 (HL)—Evolution of multicellularity Topic Practice
Students practise comparing independent origins of multicellularity across lineages using evidence of adhesion, communication, and differentiation.
How this is tested
- compare fungal, algal, plant, and animal examples to explain repeated evolution of multicellularity
- explain how cell adhesion molecules or signalling pathways enable differentiation in early multicellular organisms
