How do the parts of a plant function in order for the plant to survive? How might environmental conditions determine how well a plant grows and survives? What are the stages of the life cycle of a seed plant? Which properties of soils might influence the growth and survival of plants? growth and the medium through which water and nutrients are transferred among the atmosphere, Earth, and plants. plants. Soil is made up of different components with different properties. These properties affect plant and root growth.

Students know that plants have special parts that perform special functions in order for the plant to survive. 3.L.2.2 Students know that how well plants grow and survive is determined by a Science For All Americans (Content knowledge for adults.) Every species is linked, directly or indirectly, with a multitude of others in an ecosystem. Plants provide food, shelter, and nesting sites for other organisms. For their part, many plants depend upon animals for help in reproduction (bees pollinate flowers, for instance) and for certain nutrients (such as minerals in animal Benchmarks Reference For any particular environment, some kinds of plants and animals thrive, some do not live as well, and some do not survive at all. combination of environmental conditions. For example, drought conditions will tend to diminish plant health and growth. 3.L.2.3 Students know the distinct stages of the life cycle of seed plants (seed, germination, seedling, adult). 3.L.2.4 Students know that different soils possess different textures and capacities for the retention of water and nutrients. Students know that soil consists of different components. Students know that these characteristics of soil influence the growth and survival of plants. waste products). Plants and animals reshape the landscape in many ways. The composition and texture of the soil, and consequently its fertility and resistance to erosion, are greatly influenced by plant roots and debris, bacteria, and fungi that add organic material to the soil, and by insects, worms, and burrowing animals that break it up. The presence of life has also altered the earth's atmosphere. Plants remove carbon dioxide from the air, use the carbon for synthesizing sugars, and release oxygen. This process is responsible for the oxygen in our air today. Insects and various other organisms depend on dead plant and animal material for food. Organisms interact with one another in various ways besides providing food. Many plants depend on animals for carrying their pollen to other plants or for dispersing their seeds. Over the whole earth, organisms are growing, dying, decaying, and new organisms are being produced by the old ones. Soil is made partly from weathered rock, partly from plant remains—and also contains many living organisms.
