Answer:
osmosis; passive transport
Step-by-step explanation:
The definition of osmosis is exactly: the diffusion of water through a semipermeable membrane.
Osmosis is when water diffuses, or goes from a high to lower concentration through a semipermeable membrane (such as the cell membrane).
Therefore the first blank is "osmosis". Osmosis is one of the types of passive transport because it does not require ATP to get transported. Transport requiring ATP would be called active transport.
The second blank is passive transport because water can easily pass through a semipermeable membrane without the help of ATP molecules.
