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. In most cases, oxygen is also released as a waste product. Most plants ...
Chief cells of the stomach secrete the digestive enzymes (pepsins) of the stomach and have the typical appearance of serous-secretory epithelial cells. Secretory vesicles (containing pepsinogen) are clearly visible in the apical cytoplasm of chief cells.
Animal cells have lysosomes for digestion, centrosomes to help with cell division and sometimes flagella to help with movement â none of these three organelles are found in plant cells The cells of animals lack cell walls, chloroplasts and vacuoles which are all found in plant cells Different types of specialized cells are found in different tissues and have features relative to their function e.g. nerve cells have axons and dendrites to send and receive messages.
