Membrane proteins are important to carry out the process of selective transport across cells. Na/K channel proteins, ABC transsporters, ATP synthase, ETC chain proteins are some good examples. They mostly cost energy to transport a molecule (active transport) and other protein actually synthesize ATP (ATP synthase)
Cell
The bacterial cell membrane contains phospholipid bilayers, proteins, and other molecules necessary for cellular processes such as transport and signaling. It also serves as a barrier that regulates the movement of substances into and out of the cell.
Nucleus cytoplasm cellmembrane and chloroplasts
The cell membrane is a semi-permeable barrier that surrounds the cell, controlling the passage of substances in and out of the cell. It is made up of a phospholipid bilayer with embedded proteins that help maintain the cell's structure and function. The membrane also plays a role in cell signaling and communication.
Transport proteins are not responsible for the secretion. Golgi vesicles transport proteins. Proteins synthesis occur in cytoplasm.
what is the purpose of a democratic constitution
the cellmembrane?
Its not. many animals can eat and move their ears without it.

it selectively lets thingd transport into and out of the cell

yes. They do not however, have a membrane separating the nucleus from the rest of the cell

a cellwall is a hard fibrous structure where as the cell membran is like cling film, its really thin and flimsy

just have some sort of line you could even draw it in with marker.. just have something showing it
