This type of endocytosis is the cellular process of engulfing liquid particles by the cell membrane.
Natalija [7]

The correct answer is Phagocytosis type of endocytosis is the cellular process of engulfing liquid particles by the cell membrane.

Phagocytosis is a type of endocytosis in which large particles such as microorganisms and dead cells are ingested through large endocytic vesicles known as phagosomes. Phagocytosis is the process of detecting and absorbing particles larger than 0.5 m in size. The particle is internalized into the phagosome, a distinct organelle. This phagosome then undergoes phagosome maturation, which involves changing the structure of its membrane and the composition of its contents. The first step is to activate the phagocyte.

Step 2: Phagocyte Chemotaxis (for wandering macrophages, neutrophils, and eosinophils)...

Step 3: Phagocyte attachment to the Microbe or Cell.

Step 4: The Phagocyte consumes the microbe or cell.

mina [271]

Answer:

True

Explanation:

In  phase-contrast objective and a phase contrast optical systems is equipped with Light microscope  .

Phase contrast microscope is used to differentiate unstained structures in a cell  that differ in refractive indices and thickness. Thus it is usefull for examining  living unstained organisms.

Light that passed through materials of different refractive index and/or thickness will undergo a change in Phase. The difference in phase or wave front irregularities cause variation in brightness of the structures.
