The cell wall is a dynamic organelle that determines the cell shape and integrity of the organism during growth and cell division. It provides the cell with mechanical strength in order to withstand changes in osmotic pressure imposed by the environment and other stresses. The chemical composition ...
This micrograph image shows a plant cell and its internal organelles. The cell wall appears as the thin layer between the cells and the nucleus is the prominent, round organelle with the smaller red nucleolus. Dr. Jeremy Burgess/Science Photo Library/Getty Images A major role of the cell wall...
The term cell membrane refers to the boundary of the cell as a whole, the term plasma membrane refers to the boundary of the cell or that of an organelle within the cell. Here, then, it would be right to say that membrane-bound organelles are surrounded by a plasma membrane. ...
Plants cells monitor the integrity of their cell walls and integrity impairment leads to responses mediated by the cell wall integrity (CWI) maintenance mechanism (Rui and Dinneny2020; Somerville2004; Vaahtera et al.2019). CWI impairment is caused by cell wall damage (CWD) occurring during expos...

the cell wall is found between the two membranes, and is notably thinner (representative values, 3–7nm) than the Gram-positive cell wall (representative values, 10–30nm). While there are substantial differences among all bacteria in the structural details of their finished cell walls, the cor...

How diatoms maintain membrane homeostasis during the exocytosis of these large and rigid silica elements remains unknown. Here we study the membrane dynamics during cell wall formation and exocytosis in two model diatom species, using live-cell confocal microscopy, transmission electron microscopy and ...
