Light micrograph (LM) showing numerous calcium oxalate crystals in the epidermal layer of a cactus (Cactaceae). Calcium oxalate crystals in plants are called raphides,in humans they can appear as kidney stones. These crystals help remove calcium build-up in the tissues and make it undesirable for herbivore animals to eat the plant. Magnification: 40X at 35mm | |
