Unit 8: Cell Membrane Transport
|
Syllabus Statements
EI Membranes control the composition of cells by active and passive transport 1.3.U3 Cell Surface to volume is an important limitation to cell size 1.4.U1 Particles move across membranes by simple diffusion, facilitated diffusion, osmosis and active transport 1.4.U2 The fluidity of membranes allows materials to be taken into cells by endocytosis or released by exocytosis. Vesicles move materials within cells. 1.4.S1 Estimation of osmolarity in tissues by bathing samples in hypotonic and hypertonic solutions 1.4.NOS Experimental design- accurate quantitative measurement in osmosis experiments are essential 1.4.A2 Tissues or organs to be used in medical procedures must be bathed in a solution with the same osmolarity as the cytoplasm to prevent osmosis 4.1.S3 Recognize and interpret statistical significance. |
