Polarised light micrograph of Cinclidium stygium revealing the mosss cells filled with vibrant green chloroplasts, the organelles responsible for photosynthesis. Surrounding these chloroplasts are motor proteins likely involved in the intracellular transport and positioning of these essential organelles. The cell walls display striking birefringence colours, a characteristic phenomenon when viewed under polarised light microscopy. Magnification: x30 when printed with the longest axis at 10 centimetres long.
