Worked Solution & Example Answer:Human and plant hormones are similar in that all are A - VCE - SSCE Biology - Question 11 - 2009 - Paper 1
Step 1
C. signalling molecules that act on receptor molecules.
Answer
Both human and plant hormones are classified as signalling molecules. They interact with specific receptor molecules in target tissues to elicit biological responses. This receptor-ligand interaction is crucial for the function of hormones, allowing for precise communication within the organism.
