The semi-permeable part of the cell would be the cell membrane, which allows some molecules (water, in particular) to pass freely through but restricts the movement of other molecules (such as proteins and enzymes).
The cell membrane, also known as the plasma membrane, controls the movement of materials into and out of all cells. It is a selectively permeable barrier that regulates the passage of substances in and out of the cell to maintain internal homeostasis.
across semipermeable membrane? That is osmosis, the net movement of water.
The cell membrane regulates the movement of materials in and out of the cell through processes such as diffusion, osmosis, and active transport. Additionally, specific transport proteins embedded in the membrane facilitate the passage of certain molecules and ions.
The cell membrane, made up of phospholipids and proteins, controls the passage of substances into and out of animal cells. Selective permeability allows for the regulation of what molecules can enter and leave the cell, maintaining internal conditions necessary for proper cell function. Transport proteins, such as channels and carriers, play a key role in facilitating the movement of specific molecules across the cell membrane.
Facilitated diffusion is the movement of substances from higher to lower concentration across a semipermeable membrane with the help of specific protein carriers, without requiring energy input.

The plasma membrane selectively controls movement of materials into and out of the cell, and has receptors for hormones and enzymes. The generic term for these two processes is endocytosis (material moved into the cell) and exocytosis (movement of material out of the cell).

receptors (i believe)
The cell membrane controls the movement into and out of the nucleus. The cell membrane is a barrier that keeps cellular materials in and foreign objects out.
