Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water â hence the name photosynthesis, from the Greek Ïá¿¶Ï, phÅs, light, and ÏÏÎ½Î¸ÎµÏÎ¹Ï, synthesis, putting together.

Types of Tissue. Edit 0 5 â¦. Types of Tissue. The digestive system contains all four major tissue types, Epithelial, Connective, Muscle and Nervous. Epithelial tissue lines the entire length the digestive tract. It is made up of many different types of cells, including goblet cells that secrete mucus.There are layers of smooth muscle that line the walls of the tract, and contract to move food through.Nervous tissue is located in the tract, and transports electrical stimulus to the brain.ypes of Tissue.
