The flower needs many things to survive, like a system it’s all connected. It needs the sunlight to produce the nutrients it needs to grow, this is called photosynthesis. The stem is rigid and allows water to get down to the roots where the water is absorbed. The parts of a flowering plant are characterized by two basic systems: a root system and a shoot system. These two systems are connected by vascular tissue that runs from the root through the shoot. The root system enables flowering plants to obtain water and nutrients from the soil. Hope this helps

An informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
