what similarities and differences do you see between the bacteria and the human cells

Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.

What are two characteristics of bacteria?

There are three notable common traits of bacteria, 1) lack of membrane-bound organelles, 2) unicellular and 3) small (usually microscopic) size. Not all prokaryotes are bacteria, some are archaea, which although they share common physicals features to bacteria, are ancestrally different from bacteria.

Do bacterial cells have a cell wall?

The bacterial cell wall is a complex, mesh-like structure that in most bacteria is essential for maintenance of cell shape and structural integrity.

How are bacteria and viruses similar?

One key similarity of viruses and bacteria share is the ways that they are spread. Bacteria & viruses can both be spread by: Close contact such as touching or kissing. Being exposed to bodily fluids of someone who is infected.

What are the differences between bacterial and viral pathogenesis?

As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren’t effective against viruses.

What are 3 differences between viruses and bacteria?

Viruses are tinier: the largest of them are smaller than the smallest bacteria. All they have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can’t survive without a host. They can only reproduce by attaching themselves to cells.

Why do bacterial colonies look different?

Bacteria grow tremendously fast when supplied with an abundance of nutrients. Different types of bacteria will produce different-looking colonies, some colonies may be colored, some colonies are circular in shape, and others are irregular.

What is the difference between bacterial morphology and colony morphology?

Explain. cellular morphology shows the difference of the individual cells that is seen under the microscope. Morphology of colonies can be defined as their color, shape, edge and elevation. These features are observed with the naked eye by looking at the colony itself.

What is a colony and how does a colony relate to a bacterial cell?

What is a colony and how does a colony relate to a bacterial cell? … A colony is a mass of microorganisms that originate from a single cell. The cells that make up the colony are a clone of the original cell and are all genetically the same.

What is the key difference between bacterial and human chromosomes?

In some organisms, like humans, chromosomes are linear, but in other organisms, like bacteria, chromosomes are typically circular. In prokaryotes, the circular chromosome is contained in the cytoplasm in an area called the nucleoid.

What are two differences between a bacterial cell and a eukaryotic cell?

The most obvious difference between eukaryotes and bacteria is that there is a membrane-bounded nucleus in eukaryotes and not in bacteria – again, for the most part: there is a bacterium with the wonderful name Gemmata obscuriglobus that is described as having a double membrane enclosing the DNA in a nucleus-like …

What are similarities and differences between cells from different organisms?

Cells of plants, animals, fungi, protists, and bacteria have similarities and differences. All of these have nuclei and mitochondria, but plants and some protists have chloroplasts. Animal cells lack cell walls. All eukaryotic cells share common characteristics but also have differences in their cell structures.

What is the difference between cells in a tree and bacteria cells?

The plant cell has a well-defined nucleus that stores the genetic material and also coordinates the cell’s activities such as cell division, metabolism, growth, and protein synthesis. Bacterial cells lack membrane-bound nuclei. The genetic material lies suspended in the cytoplasm.

What are the differences and similarities between prokaryotic and eukaryotic cells?

No prokaryotic cell has a nucleus; every eukaryotic cell has a nucleus. Prokaryotic cells have no mitochondria; nearly every eukaryotic cell has mitochondria. Prokaryotic cells have no organelles enclosed in plasma membranes; every eukaryotic cell has a nucleus and organelles, each enclosed in plasma membranes.

What are the similarities and differences of prokaryotic and eukaryotic cells?

Comparison chart

Eukaryotic Cell Prokaryotic Cell
Nucleus Present Absent
Number of chromosomes More than one One–but not true chromosome: Plasmids
Cell Type Usually multicellular Usually unicellular (some cyanobacteria may be multicellular)
True Membrane bound Nucleus Present Absent
