[Clarification Statement: Emphasis is on the cell functioning as a whole system and the primary role of identified parts of the cell, specifically the nucleus, chloroplasts, mitochondria, cell membrane, and cell wall.] CELLS CHUNK 1 Membranes Engage Concept (DCI of concept from CF) Engage Concept (DCI of concept from CF) Explore/Explain Concept #1 Explore/Explain Concept #2 Elaborate Evaluate Concept Concept SEP Phenomenon Cell sizes are typically within a range of 1-20 micrometers. Interactions with water determine shapes and structures in the living cell Membranes are assembled by the interactions between lipids and water Arguing from evidence; mathematical thinking. Developing models, Constructing explanations Cells are small within 1-10 microns across. The selective cell membrane controls what goes into and out of the cell. Cells can burst or shrivel and die if placed in nonisotonic solutions. Plant cell wall is protective against hypotonic solutions.
