Phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles. The phagocyte may be a free-living one-celled organism, such as an amoeba, or one of the body cells, such as a white blood cell.

A white blood cell engulfs a bacterium through a process called endocytosis.

White blood cells engulf bacteria through what process? phagocytosis. In receptor-mediated endocytosis, receptor molecules initially project to the outside of the cell.

Fimbriae and pili can often be found on the surface of bacterial cells. Fimbriae are short, hair-like projections that attach a bacterium to a substrate or other cells. Pili are similar structures that can serve many functions, including helping the bacterium move or helping it transfer DNA to another bacterium.

Prokaryotes include the domains, Eubacteria and Archaea. Examples of prokaryotes are bacteria, archaea, and cyanobacteria (blue-green algae).

In transformation, a bacterium takes in DNA from its environment, often DNA that’s been shed by other bacteria. In a laboratory, the DNA may be introduced by scientists (see biotechnology article).

There are three types of recombination; Radiative, Defect, and Auger. Auger and Defect recombination dominate in silicon-based solar cells. Among other factors, recombination is associated with the lifetime of the material, and thus of the solar cell.

Most bacteria have a haploid genome, a single chromosome consisting of a circular, double stranded DNA molecule. However linear chromosomes have been found in Gram-positive Borrelia and Streptomyces spp., and one linear and one circular chromosome is present in the Gram-negative bacterium Agrobacterium tumefaciens.

No, bacteria do not have endoplasmic reticulum because bacteria is a prokaryotic organism that lacks member bound organelles such as the nucleus, endoplasmic reticulum, mitochondria, lysosomes, Golgi apparatus, etc.

Bacteria are neither animals nor plants.

It is a gel-like matrix composed of water, enzymes, nutrients, wastes, and gases and contains cell structures such as ribosomes, a chromosome, and plasmids. The cell envelope encases the cytoplasm and all its components. Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus.

Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid.

Short story: Human cells are eukaryotic which means they are more complicated, bacteria cells are prokaryotic which means they are simpler and viruses are not even cells at all, they are just genetic material in a protein shell.

no membrane bound organelles- but there are numerous inclusions and granules. Numerous small ribosomes in cytoplasm. many membrane bound organelles- lysosomes, mitochondria (with small ribosomes), golgi bodies, endoplasmic reticulum, nucleus.

Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane.

Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids.

The Golgi apparatus transports and modifies proteins in eukaryotic cells. How have scientists studied dynamic protein movements through the Golgi? The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell.

The Golgi apparatus (GA), also called Golgi body or Golgi complex and found universally in both plant and animal cells, is typically comprised of a series of five to eight cup-shaped, membrane-covered sacs called cisternae that look something like a stack of deflated balloons.

A major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes.

The Golgi is located right near the nucleus. It’s called a perinuclear body, and it’s actually right near the endoplasmic reticulum as well.

(GOL-jee BAH-dee) A stack of small flat sacs formed by membranes inside the cell’s cytoplasm (gel-like fluid). The Golgi body prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell. The Golgi body is a cell organelle.
