Angiosperms (flowering plants) and vertebrates obtain nutrients their environment in different ways: (a) discuss the type of nutrition and nutritional needs of angiosperms and vertebrates. (B) Describe two structural changes in angiosperms for obtaining nutrients from the environment. Relate structure to function. (C) Interdependence in nature is evident in symbiosis. Explain two symbiotic relationships that aid in nutrient uptake, using examples from angiosperms and / or vertebrates. (Both examples may be angiosperms, both may be vertebrates, or one can be in each group.

(A) The nutritional needs of angiosperms are very simple compared to the nutritional needs of vertebrates. Due the plants produce their own carbon-based nutrients through photosynthesis, which require only inorganic nutrients to survive. The essential elements that use plants in relatively large amounts are called macronutrients. The major macronutrients are nitrogen, phosphorus and potassium. Calcium, magnesium and sulfur are the macronutrients. (B) The structure of a root system of the angiosperms has evolved so that branches extensively (compare this with the relatively simple "as root" the structure of algae). This branching pattern enables the plant to explore the area's soil and more effective absorption of nutrients that are not mobile, such as phosphorus. Another structural adaptation of flowering plants is the formation of root hairs. These are growths on the surface of epidermal root and role in helping the absorption of nutrients and water by the exponential increase in the surface of the roots. (C) Mychorrizal symbiosis is the association of a fungus with a root of the plant. The benefits of the fungus through the development of coal resources of the plant and phosphate plant of much needed income and other minerals in most surface provided by the fungal hyphae. Another symbiotic relationship between plants is known as angiosperms certain legumes and species of bacteria Rhizobium, Bradyrhizobium, and Azorhizobium. These species of bacteria find a nice home in the roots of leguminous plants by inducing the formation of unique structures, called nodules on the roots or stems of the legume host. In these nodules, rhizobia fix atmospheric nitrogen by converting ammonia N2 the plant.
