To determine which animal system has a function similar to the plant system shown in the diagram, we need to identify the function of the plant system in question.
If we assume the plant system is related to the transport of nutrients and water (like the vascular system in plants), then the animal system with a similar function would be the circulatory system. The circulatory system in animals is responsible for transporting oxygen, nutrients, hormones, and waste products throughout the body, similar to how the vascular system in plants transports water and nutrients.
If, instead, the plant system pertains to gas exchange (like stomata), then the respiratory system in animals would be more comparable.
Without seeing the specific diagram, the most likely answer, given the general context of plant systems, would be circulatory if we are discussing nutrient and water transport, or respiratory if it’s about gas exchange. Please clarify which plant system is being referred to for a more accurate answer!
