Semi permeable membranes as the plasma membranes in cells of our body.
Plasma membrane
Selectively permeable membranes can be found in several locations within a plant cell, most notably in the plasma membrane that surrounds the cell. This membrane regulates the movement of substances in and out of the cell, allowing essential nutrients to enter while keeping harmful substances out. Additionally, selectively permeable membranes are present in the tonoplast, which encloses the central vacuole, and in the membranes of organelles such as chloroplasts and mitochondria, each controlling the exchange of materials specific to their functions.
Neuron plasma membranes are most permeable to potassium ions (K+) due to the presence of leak potassium channels. This allows for the resting membrane potential to be closer to the equilibrium potential for potassium. Sodium ions (Na+) and chloride ions (Cl-) also play roles in membrane potential, but potassium ions have the highest permeability.
Small, uncharged molecules like oxygen and carbon dioxide are permeable to phospholipids in the plasma membrane, while ions such as sodium (Na+), potassium (K+), and chloride (Cl-) are not permeable due to their charge.
Plasma membranes are selectively permeable.

Because they can dissolve the lipid bilayers of epidermal and dermal cell plasma membranes.

The biological theme - membranes - is explored in two ways thusly: permeable membranes and semi-permeable membranes.
Neuron plasma membranes are most permeable to potassium ions (K+) due to the presence of leak potassium channels. This allows for the resting membrane potential to be closer to the equilibrium potential for potassium. Sodium ions (Na+) and chloride ions (Cl-) also play roles in membrane potential, but potassium ions have the highest permeability.
Cells have impermeable, permeable and selectively permeable membranes.
Membranes that are permeable (loose) tend to have lots of what?
they have selectively permeable membranes
plasma membrane and other membranes are the same
no animal cells also have plasma membranes
