(In words) Stimulus → Receptor → Sensory neurone → Relay neurone → Motor neurone → Effector → Response.
Since experimental design constitutes a significant portion of your final grade, your notes must treat practicals as core theory. Exceptional notes include step-by-step breakdowns of mandatory experiments (e.g., testing a leaf for starch, investigating enzyme activity, or using a potometer to measure transpiration). They should explicitly outline independent variables, dependent variables, controlled variables, and common sources of experimental error.
