Verified step by step guidance1
Step 1: Begin by understanding the concept of organ systems. Organ systems are groups of organs that work together to perform specific functions necessary for the survival of an organism.
Step 2: Review the major organ systems found in mammals, including rats. These typically include systems such as the respiratory system, endocrine system, digestive system, circulatory system, nervous system, and others.
Step 3: Consider the photosynthetic system mentioned in the question. Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy into chemical energy. Mammals, including rats, do not possess a photosynthetic system because they are heterotrophic organisms and rely on consuming food for energy.
Step 4: Compare the photosynthetic system to the other options provided (respiratory, endocrine, and digestive systems). All of these systems are essential for mammalian life and are present in rats.
Step 5: Conclude that the photosynthetic system is not a major organ system found in rats, as it is exclusive to autotrophic organisms like plants.
