Materials can pass through the cell membrane because it is semi-permeable. Materials diffuse through the membrane if they have the correct requirements. It is important for materials to pass through the membrane so the cell can communicate with other cells, receive nutrients, and expel waste ...

Directional cell movement through tissues is critical for multiple biological processes and requires maintenance of polarity in the face of complex environmental cues. Here we use intravital imaging to demonstrate that secretion of exosomes from late end
Introduction: Cells, the smallest functional unit in an organism, contain several organelles and carry out functions of life. The cell membrane is an organelle that holds thecell’s contents, and it allows for certain molecules to pass through, which is why it is referred to as selectively per...
a The filament is a helical structure composed of a protein called flagellin. The hook is anchored to the cell by the basal body, a stack of rings firmly anchored through the cell wall to the cell membrane. The hook and the filament are free to rotate -like a tiny propeller. 细丝是一...
