 Phytochrome is a photoreceptor, a pigment that plants use to detect light

  phytochrome is a protein


 Mannitol (also referred to as mannite or manna sugar) is a white, crystalline solid with the chemical formula C6H8(OH)6.

 It was originally isolated from the secretions of the flowering ash and called manna after its resemblance to the Biblical food.

 In plants, it is used to induce osmotic stress

It has several industrial uses, but is mainly used to produce tablets of medicine

 Mannitol increases blood glucose to a lesser extent than sucrose (thus having a relatively low glycemic index) and is therefore used as a sweetener for people with diabetes, and in chewing gums
