Lettuce is an annual pant which belongs to daisy family. It is the most grown leafy vegetable but sometimes grown for its seed and stem. Lettuce is easily cultivated and generally grown as a hardy annual plant. It requires less temperature. Crenate means contraction of cell after exposure to hypertonic solution. Hypertonic solutions are those solutions that have high concentration of solute. Hypotonic solutions are those solutions that have lower concentration of solutes than the solution
