QUESTIONS & VALID CORRECT ANSWERS
fasten cells together into strong
sheets. gap junctions
provide cytoplasmic channels
between ad- jacent cells.
7. Which molecules pass a membrane freely by diffusion O2
H2O
non-polar nolecules
CO2
8. Transport vesicles migrate to the membrane, fuse with exocytosis
it, and release their contents outside the cell:
A cell engulfs a particle in a vacuole: 11. Look at the
picture
Molecules dissolved in droplets are taken up
when extracellular fluid is "gulped" into tiny
vesicles:
Binding of specific solutes to receptors triggers
vesicle formation:
9. During osmosis, the net water movement
through a semipermeable membrane is
towards the higher solute concentration.
