Understanding Root Anatomy. Next Generation Science/Common Core Standards Addressed! HS‐LS1‐2. Develop and use a model to illustrate the hierarchical.
II. The Cell Membrane. A. Cell Membrane Function 1.Transport Proteins are selectively permeable- regulate what materials enter and exit the cell 2.Enzymes.
Plants The study of plants is called Botany. What is a plant? Multicellular eukaryote Produce their own food through photosynthesis Have thick cell walls.
