Answer:
Osmosis is the process that best describes the movement of water molecules into and out of the cell.
Explanation:
- Osmosis can be understood as the net shift of water molecules or its movement between the permeable membranes.
- Osmosis is caused by the difference in solute concentration between the consecutive membranes.
- Osmosis process do not transfer any ions and solutes contained by the water molecules.
- The movement of water is always from the lower concentration level to higher concentration level.
- Example of osmosis can be seen during the absorption and secretion of water in our small intestine.
Active transport: Movement of materials across a membrane that requires an input of energy from a cell. Movement of material against the concentration gradient (from low concentration to high concentration)
Passive transport: Movement of materials across a membrane that does not require energy from the cell. Movement of material against the concentration gradient (from high concentration to low concentration)

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Answer:
They can be either of the same species (intraspecific interactions), or of different species (interspecific interactions). These effects may be short-term, like pollination and predation, or long-term; both often strongly influence the evolution of the species involved. A long-term interaction is called a symbiosis.
Answer:
The Viking tubing is meant to be the cell membrane. Glucose manages to move out of the bag and into the surrounding water but starch does not. Not all substances can pass through the cell membrane; some molecules, like starch are too large. The cell membrane is called selectively permeable because of this.
