The cell membrane allows only certain things to pass in and out of the cell.

Yes the cell membrane lets things past through it. The cell wall does not allow things to pass through.
Things can pass in and out through the cell.
Cell membrane
A plant's Cell Membrane is very thin and lets things pass in and out of the cell.
The permeability of the cell membrane controls which substances may pass in or out of the cell.
Semi-permeable means that which only allows certain things to pass through. The cell membrane needs to be semi permeable so that it only allows beneficial things (say, ions or water molecules) into the cell whilst keeping harmful things out (eg. toxins and viruses). That's all. Hope this helps you (:
Water, sucrose, ions, amino acids and proteins with molecular weight less than 20,000 can pass through the cell wall
That would be cell membrane.
The cell membrane surrounds the protoplasm of a cell and separates the intracellular components from the extracellular environment. The cell membrane also helps in anchoring the cytoskeleton to provide shape to the cell, and in attaching to the extracellular matrix and other cells to help group cells together to form tissues.
