Natural Science 1.Use appropriate terminology related to cell structure and sustainable ecosystems, including, but not limited to cell membrane, nucleus, cytoplasm, organelles, absorption, anaphase, capillaries, concentration, differentiation, diffusion, meristematic, red blood cells, regeneration, bioaccumulation, biosphere, diversity, ecosystem, equilibrium, sustainability, sustainable use, protection, and watershed 2.Identify structures and organelles in cells, including the nucleus, cell membrane, cell wall, chloroplasts, vacuole, mitochondria, and cytoplasm, and explain the basic functions of each (e.g., the nucleus holds all the information needed to make every cell in the body) 3.Compare the structure and function of plant and animal cells 4.Identify unicellular organisms (e.g., amoebae) and multicellular organisms (e.g., invertebrates [worms], vertebrates [frogs]), and compare ways in which they meet their basic needs (e.g., nutrition, movement, gas e 5.Explain cell organisation by describing the link between cells, tissues, organs, and systems in the human body 6.Explain the primary functions of a variety of systems in animals (e.g., the circulatory system transports materials through the organism; the respiratory system supplies oxygen to and removes carbon dioxide from the body) with specific focus on: NS4.1 NS4.2,NS4.3NS4.4,NS4.12,NS4,15,NS4.13,NSN5.2,NS5.3,NS5.4,NS5,5,NS5.12,NS5,13
