what is chitin and acrosoe?
chitin is the stuff that hyphae (in fungi) are made of.
acrosome is the sperm head, which contains enzymes used to digest the wall of the egg and nutrients to keep sperm alive.

about eye, you must know sclera, cornea, lens, suspensory ligaments, iris, pupil, retina, fovea, optic nerve, blind spot,
about Kidney you dont need to know, it is specifically mentioned in the syllabus that working of kidney not required
about plants, you have to learn all parts, including parts developing from flower to seed to plant.
heart, you have to know ventricles, atria, position of valves, the arteries and veins connected, coronary arteries.
locomotion: hinge joint, ball and socket joint, ulna, radius, humerus, biceps, triceps, and how they are connected (by ligaments or tendons) to bones!
so many! all have to memorise except kidney!
