In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. Like the exterior walls of a house ...

Lipids in cell membranes regulate the activity of a cancer-linked protein, cell biologists at RIKEN have discovered. This ...

Lysosomes are membrane-bound organelles in cells that act as recycling centers—breaking down waste materials, damaged ...

Cell structure Description Function Cell type Cell wall Freely permeable layer surrounding cell membrane. The cell wall of plant cells is made from cellulose. This gives them a rigid structure.

This barrier tissue performs its function thanks to specialized ... "These changes make the apical membrane—the top of the cell—less stiff and certain constituents of the tight junctions ...

Each component of a cell has its own function. Animal and plant cells differ and they have similarities. Nucleus, cell membrane, cytoplasm and mitochondria are four cell components that are found ...
