Your cheek cells and the cells inside a mango leaf look completely different under a microscope and those differences reveal something deep about how plants and animals survive. Plant cells have a rigid cell wall, a large central vacuole, and chloroplasts (the green machines that manufacture food from sunlight). Animal cells have none of these! But WHY? Each structural difference is a solution to a different survival challenge. Spotting and explaining these differences is a key skill in biology not just memorising a list but understanding the reasoning behind each one. Let Avinto help you master this!
