Botany Unit 2: practical aim
Compare transpiration rate from upper and lower surfaces using cobalt chloride paper/potometer idea. The 3D lab gives a realistic apparatus view, guided steps, calibrated controls and a student observation table so the practical can be rehearsed before the school lab.
How to use the virtual practical
Use the compact controls to change specimen, concentration, field, time or instrument setting. Press Next step to follow the method. Press Record to add the current observation to the practical notebook. Rotate the model only when you need a closer view; Reset view returns the correct examination angle.
Observation and result
Record the observation under “Transpiration rate”, include units where applicable, and write the conclusion with a reason. In microscopy practicals, count multiple fields; in physiological and biochemical practicals, compare the experimental tube with a control.
