What type of taxis is a bacterial cell exhibiting when it moves toward glucose in the environment?
Chemotaxis - this is the general term for bacterial motility when sensing a compound in the environment. If moving toward it is called positive chemotaxis, if away from it is negative chemotaxis.
An oriented movement in response to light or chemical stimuli?
Movement in response to light is called phototaxis, and in response to chemicals is chemotaxis. More specifically, movement towards a stimulus is positive and away from is negative. For example, positive chemotaxis is movement of a cell towards nutrients.
How do bacteria carry out Chemotaxis?
Bacteria carry out chemotaxis by sensing chemical gradients in their environment using specialized receptors on their cell surface. When these receptors detect attractants or repellents, they trigger a signaling cascade that alters the rotational direction of the flagella, allowing the bacteria to move toward favorable conditions or away from harmful substances. This movement is typically characterized by a series of "runs" (straight movement) and "tumbles" (random changes in direction) that help the bacteria navigate through their surroundings. Overall, chemotaxis enables bacteria to effectively locate nutrients and avoid toxins.
The plasma membrane is best described as?
The plasma membrane forms the outer border of the cell, separating it from bordering cells and/or the external environment. it is composed primarily of a bi-lipid layer in addition to various proteins and cytoskeletal components. It performs multiple tasks, and contains many receptors and cell-to-cell channels whereby cells can communicate and interact with each other. There are several methods of describing cell movement, but in a single cell (classically in a white blood cell) chemotaxis is the method where the cells sense and respond to a specific stimulus by migrating toward it along a chemical gradient. This type of movement could be described as amoeboid if the cell forms pseudopods (legs), flagellate if they have a tail (flagellum) or migratory if the cell is present within a blood vessel where it attaches to specific receptors on the inside of the blood vessel, begins to roll, then attaches and leaves the vessel through small channels (again, typical of chemotaxis).
Where would you probably not find a cell?
In a prison.

In becterial cell why the cross wall is taking place at center of cell?
Movement of a cell toward a chemical stimulus is termed?
positive chemotaxis
What is Protoplast Fusion in Becterial cell?
it is a technique by which protoplast cells are fused to get new hybrid.
What is the process whereby neutrophils and other white blood cells are attracted to an inflammatory site?
chemotaxis, not phagocytosis, pahgocytosis is when a cell engulfs something by the cell membrane.
Attraction or repulsion of certain cells to chemicals in their environment in cells are?
Cell movement in response to chemicals in their environment is called chemotaxis. This process involves cells sensing and following a chemical gradient, either towards an attractant or away from a repellent, to reach a specific location. Chemotaxis is crucial for various cellular activities, including immune responses and wound healing.

What is chemotaxic?
Chemotoxin is a term employed to name a protein that results of the fusion of a chemokine and a toxin.Usually this fusion is accomplished by mean of genetic engineering techniques. Some chemotoxins are being developed as therapeutic with the goal of deliver a toxin to cells that express in the membrane a receptor which is specific for the chemokine and thus only the cells expressing that receptor will be damaged. Such a treatment would be useful against tumor cell or in certain autoimmune diseases.
What is the role of the flagella in a bacteria cell?
The role of a flagella in a bacterial cell is motility. Through the back and forth movements of the flagella bacteria can propel themselves through their environment. The flagella also help bacteria undergo chemotaxis, the ability to move away from some stimuli and move towards others.
Does Paris Jackson have a cell phone?
