:(cell eating). a process in which large food particles are engulfed by the cell and brought into the cell for intracellular digestion.

Phagocytosis

Explanation:

Phagocytosis involves the feeding on solid food materials by individual cells. It is carried out by protozoa such as amoeba. When an amoeba approaches the microorganism, several finger-like projections called pseudopodia are formed that enclose the food forming food vacuole.

Phagocytosis

Explanation:

The process by which the cell takes large particles inside itself is called phagocytosis. Phagocytosis is a type of endocytosis, the general process for taking large molecules into the cell.

Phagocytosis is performed only by some specific cells, such as the cells of the immune system, where they engulf and destroy pathogens.

The cell membrane is flexible and fluid, and when it encounters a large particle or cell it would like to engulf, it contacts the particle and creates a pocket, which eventually encloses the membrane.

The particle is then enclosed in a compartment in the cytoplasm called a phagosome, and is protected from the rest of the cell contents. From here, the cell can break down the products in the phagosome.

why many students visually perceive stem as a vapid class?

for many students, however, stem subjects are optically discerned as vapid, tedious, and destitute of authentic-world applications. science and math have always been a major part of the high school curriculum, but many students have disengaged from these subjects because they don’t optically discern that they have any pertinence to the authentic world or students’ daily lives. for them, math and science have become a set of rules, procedures, laws, theorems, and formulas to memorize. some students even develop math apprehensiveness and cerebrate they are incapable of learning higher-level mathematics.

why is stem paramount?

as the u.s. economy changes, the ordinant dictation for stem-capable workers is growing. in may of 2014, the u.s. bureau of labor statistics counted more than 8.3 million stem jobs, which accounted for 6.2 percent of total employment in the cumulated states. that number is expected to perpetuate to increment as u.s. companies grow and innovate to compete in the ecumenical economy. according to the u.s. department of labor, the average salary for all stem jobs is $85,570, which is virtually double the average salary for all jobs.

many people still envision stem professionals as wearing a white lab coat and conducting research in a laboratory. in authenticity, some of the most in-demand stem fields are petroleum engineering, process engineering, and computer engineering. these fields that are experiencing shortages of qualified candidates are additionally among the highest paying, with the average petroleum engineer earning an annual salary of $147,520 in may 2014 according to the u.s. bureau of labor statistics.

in additament, stem subjects edify students valuable skills that are vital for prosperity in all vocations, even those that do not directly require stem erudition. engagement in stem subjects avails students develop quandary-solving, critical mentally conceiving, and leadership skills. these skills are so ecumenical, in fact, that statistics relinquished in the summer of 2013 by the u.s. census bureau designated that about three-quarters of the people with a bachelor’s degree in stem fields are not working in those vocations. many non-stem employers are poaching stem-qualified job candidates because they are more ingenious and collaborative than their non-stem counterparts.

as the ecumenical economy perpetuates to evolve, the desideratum for stem-capable workers will perpetuate to grow. by getting edifiers and students involved in the stem kineticism, an incipient generation of adroit workers will be poised to energize and expand this exhilarating field.
