ESSENTIAL QUESTIONS:
MECHANISMS OF CELL TRANSPORT
1.4.U1 Particles move across membranes by simple diffusion, facilitated diffusion, osmosis and active transport.
PASSIVE TRANSPORTACTIVE TRANSPORT
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.
MEASUREMENT PRECISION & UNCERTAINTY
1.4.NOS: Experimental design- accurate quantitative measurement in osmosis experiments are essential
OSMOSIS LAB - PP2
1.4.S1 Estimation of osmolarity in tissues by bathing samples in hypotonic and hypertonic solutions. (Practical 2)
MEMBRANE FLUIDITY
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.
- What are the different methods of transport for a cell?
- How do the properties of the plasma membrane assist with cell transport?
- Why do certain molecules need specific types of transport?
