11/10/2022 0 Comments Bacteria shapes![]() ![]() Among these different factors, our understanding of the relationship between motility and cell shape is most complete for example, highly motile bacteria are usually rods with a specific (optimal) shape and size, and movement through viscous fluids seems to a favor spiral shape. ![]() Further he explains what in general gives the shape to bacteria:īacterial morphology is affected by a combination of selective pressures - access to nutrients, cell division, attachment/dispersal, predation and motility (among others). These factors play a role in shaping bacteria. Predation: In their struggle against being eaten, bacteria have adopted morphological defenses that may have produced the wealth of shapes we now observe.Fast cells are better off as rods with a certain length-to-width ratio, chemotactic cells must adopt shape ratios in line with their environments, and cells that forage near surfaces or navigate viscous environments may do best if they are slightly curved or spiral. Motility: Motility imposes a heavy selective pressure on cell shape.Nutrient uptake: Cell shape, in and of itself, affects nutrient acquisition and argues that other nutritional situations may create conditions that favor one bacterial shape over another.Young Bacterial morphology: Why have different shapes? which highlights 3 main points which defines the shape of Bacteria: ![]() There is an article based on research by Kevin D. The wide variety of shapes is determined by the bacterial cell wall and cytoskeleton, and is important because it can influence theĪbility of bacteria to acquire nutrients, attach to surfaces, swim Reasons for Bacteria with different shapes as given in Wikipedia/Bacteria: ![]()
