An Organ is the collection of similar organ that comes together to perform a tissue 3aii). * Cell level of organization * Tissue level of organization * Organ level of organization * System level of organization 3bii). * They are specific in action * They are proteinous in nature * They are affected by temperature * Action on enzymes are reversible 4b). Photosynthesis 1. It is an anabolic process in which food material is synthesized and energy is stored. 2. Carbon dioxide, water, chlorophyll and light act as raw mate4rials. 3. In natural conditions it takes place in daytime, because light is essential for this process. 4. Only chlorophyll containing cells can carry out the process of photosynthesis. WHILE Respiration 1. It is a catabolic process in which food material is broken down and energy is release. 2. Carbohydrates, like glucose, act as raw materials. Oxygen is required in aerobic respiration 3.
