its either the cell membrane, molecules, or plasma
The cell wouldn't diffuse.
The thin structure that surrounds the cytoplasm of a cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa. However plant cells, in addition to the cell membrane also have the cell wall outside the cell membrane. This provides mechanical rigidity to the cell and prevents the flow of larger particles.
Phagocytosis which literally means "cell eating" is the process by which cells ingest bacteria and other large foreign particles.
A vacoule is the excretory organelle of the cell. It regulates the turgidity of the cell by regulating the amount of water inside the cell. The vacoule always has some amount of water present inside it. If the cell contains more water, it absorbs the water and allows it to diffuse out of the cell. If the cell contains less water, the water from the vacoule will re-enter the cell to maintain its turgidity.
In plants, the vacuole stores food, water, and enzymes, and absorbs the waste products in the cell. In animal cells, smaller vacuoles are used to transport lipids and proteins out of the cell.
The water salts and sugars will match the water concentration within the blood cell, therefore water does not enter or leave the cell, resulting in the cell not swelling.
Not everything, no. It depends on the cell, some cell membranes are permeable to water (called osmosis) but not smaller particles like proteins. Whereas, some are permeable to proteins and other small particles but not to larger particles.
The cell absorbs water through its semipermeable membrane in order to make the ratio of salt particles to water particles equal in the cell and outside the cell. However, the increase in water in the cell makes it explode.
A vacuole is a membrane-bound sac that contains water and other substances. You can think of it as the refrigerator of the cell because it stores salts, carbohydrates, sugars, and water.
semi permeable means the cell chooses what comes into it, they have this so they can let food particles and water in but not large items or other cells
water
turgidity, stores sugars/water soluble products
If is Hypotonic, that the water will go inside the cell. If is Hypertonic, That the water will go outside the cell.
I assume you mean in plant cells. This is called the vacuole, and its not "water filled" its filled with a mix of water, sugars, waste products and lots of other things.
energy is not required.
Small particles can pass through the cell membrane by simple diffusion. If the particles are water, the process is given a special name: osmosis.
cytoplasm, containing 90% water, ions, sugars, amino acids, and ATP.
