Answer #1

The process of phagocytosis occurs when a cell binds to bacteria or viruses that are foreign to body. It destroys by engulfing on the cell surface and draws the bacteria and destroy it.

Steps of phagocytosis:


1. The plasma membrane which is outer membrane of cell extends around the bacterial cell and engulf it.

2. Bacteria is placed into a phagosome which is lysosomes containing vesicle.

3. Cytoplasm of cell contains lysosomes organelles that fuses with the phagosome and forms phagolysosome.

4. The hydrolytic enzymes of the lysosomes involves the digestion of the molecules of bacteria and thus destroy the bacteria.

5. The soluble products of digestion will be absorbed by cytoplasm of the phagocyte.

6. Undigested materials will be released by exocytosis.

A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of m = 0.700 fg (where a femtogram, fg, is 10−15g) and is swimming at a velocity of v = 5.00 μm/s , with an uncertainty in the velocity of 9.00 % . E. coli bacterial cells are around 1 μm ( 10−6 m) in length. The student is supposed to observe the bacterium and make a drawing. However, the student, having just...
