Can sugar molecules pass through the membrane
WebIf a molecule crosses a plasma membrane faster than it diffuses in water, then the process is likely to involve active transport. True or False True When you cut into most active plant tissue, water appears almost immediately because plant cells contain a. a hypertonic solution that produces turgor pressure.
