Learning objectives. Identify . major systems in plants. Describe the interactions that occur among systems to carry out vital plant functions. Interactions Among Plant Systems. Organ systems:. Where do Plants get their nutrients?. PLANT: A SUGAR FACTORY. NUTRIENTS AVAILABILITY AND SOIL. The relative availability of nutrients to plant roots depends on the pH level of. the soil.. Plant Nutrients Content in % Compared to Nitrogen. continued. Water. Plants require water for growth, temperature regulation, and for support. . Remember . that water is one of the reactants needed for photosynthesis. A plant that does not have sufficient amounts of water will wilt. . C. Crawford . Dublin City Schools, Dublin, Ohio. & . M. Dunn. Miami University, Oxford, Ohio. Developed Spring - Summer 2013. Leading Questions. In your lab notebook answer the following:. What environmental factors are required for a plant to sprout?. Chapter 9.3 and 9.4. Growth in Plants. Undifferentiated cells in the meristems of plants allow indeterminate growth. Determinate: growth stops when a certain size is reached. Indeterminate: when cells continue to divide indefinitely. Plant Hormones. Plant Hormones. Naturally occurring compounds produced by the plant to accelerate or inhibit the rate of growth or maturation. Produced in minute quantities, but can have a large affect on growth. Learning outcomes.
