Question

Which of the following terms can be defined as the movement of water across a cell membrane?

a- exocytosis
b-osmosis
c-active tranport
d-facilitated diffusion

Answer 1

It's C-active transport

Answer 2

b-osmosis

Step-by-step explanation:

Osmosis is the movement of water that occurs within cells through a semipermeable cell membrane. This process is performed from a medium with lower water concentration to another with higher concentration.

In osmosis, the solvent (water) is passed from one medium to another across a cell membrane. This process does not cause energy waste and therefore osmosis is considered a passive transport. In the osmosis process, water, which is the solvent, tends to cross the semipermeable membrane in order to balance the solution concentration. This action is performed until the osmotic pressure is stabilized.
