Divisome and elongasome complexes responsible for peptidoglycan synthesis during lateral cell-wall growth and division. [1]The divisome is a protein complex in bacteria that is responsible for cell division, constriction of inner and outer membranes during division, and peptidoglycan (PG) synthesis at the division site.
A plant cell wall was first observed and named (simply as a "wall") by Robert Hooke in 1665. [3] However, "the dead excrusion product of the living protoplast" was forgotten, for almost three centuries, being the subject of scientific interest mainly as a resource for industrial processing or in relation to animal or human health.
A frustule is the hard and porous cell wall or external layer of diatoms. The frustule is composed almost purely of silica , made from silicic acid , and is coated with a layer of organic substance, which was referred to in the early literature on diatoms as pectin , a fiber most commonly found in cell walls of plants .
Cell mechanics is a sub-field of biophysics that focuses on the mechanical properties and behavior of living cells and how it relates to cell function. [1] It encompasses aspects of cell biophysics , biomechanics , soft matter physics and rheology , mechanobiology and cell biology .
The cell plate that is formed during cell division itself develops into middle lamella or lamellum. The middle lamella is made up of calcium and magnesium pectates. [2] In a mature plant cell it is the outermost layer of cell wall. [3] [4] In plants, the pectins form a unified and continuous layer between adjacent cells.
Sending migrants back to their home countries, which is called repatriation, remains one of the most contentious aspects of Trump’s plan to deport millions of immigrants who are in the U.S ...
Plant cell overview, showing secondary cell wall. The secondary cell wall has different ratios of constituents compared to the primary wall. An example of this is that secondary wall in wood contains polysaccharides called xylan, whereas the primary wall contains the polysaccharide xyloglucan. The cells fraction in secondary walls is also ...
