NEB Biology Practicals — Class 12

Class 12 Biology now has its own full practical course. It includes plant anatomy, physiology experiments, genetics, embryology, biotechnology, animal tissue slides, animal mitosis, frog development, food and clinical tests, amylase activity, skeleton/joints and cockroach morphology. The combined “observation and comments” practical is split into separate 3D setups so students can practice each one clearly.

You will learn: donePlant anatomy and physiology experiments doneBiochemical and clinical test interpretation doneGenetics ratio and chi-square style observation doneEmbryology and animal tissue microscopy doneHuman skeleton, joints and insect morphology
