Human cells can widely vary in form and function, even in a single human, because of the multicellular structure. Bacteria, on the other hand, are single-celled, and as such every cell is mostly the same.
Bacteria don't have DNA <--this is not true. Their DNA is circular rather than a double-helix like humans but it still comprises a chromosome and is written in exactly the same type of code using the same four bases. Their cells do not contain membrane-bound organelles like mitochondria, and their outer structure is markedly different from humans consisting of peptidoglycans-these differences are a major target for many antibacterial drugs which is how they harm bacteria while leaving human eukaryotic cells alone. Penicillin for example inserts itself into the prokaryotic bacterial cell's machinery used for building its cell wall and causes it to be weak and the bacteria simply split open as they enlarge.
A human cell --------
1. is eukaryotic
2. has a well defined nuclear region surrounded by a nuclear membrane
3. has more than one chromosomes
4. has membrane bound cell organelles
A bacterial cell ------
1. is prokaryotic
2. does not have a well defined nuclear region, which is known as nucleoid and also the nuclear membrane is absent
3. has a single chromosome
4. does not have membrane bound cell organelles
Bacterial cells are prokaryotic while human cells are eukaryotic. Human cells have a membrane bound nuclues, bacterial cells do not. Human cells have DNA, bacterial cells have plasmid. Cell division occurs differently. Cell shapes differ.
This answer is from a girl in 6th grade. I go to The Delta Honors Program in MS 54. I learned about cells and stuff in the beginning of the year!
Animal cells(humans are animals too) are eukaryotic. Bacteria cells are prokayotic.
If you're asking about the structure then bacteria cells have flagella and pilus, which allows the bacteria cell to move and it also has cilia and plasma membrane which our cells doesn't have. Human cells have endoplasmic reticulum/Smooth),Golgi Apparatus,Ribosomes,Lysosomes,Centriole,Vacuole, and etc.
the genetic material is inside the nucleus, bacteria cells have flagella, and they have a cell wall.
Bacterial cells don't have a nucleus, because there's no cell membrane to hold it in, instead they have nucleic acid floating around. They also do not have organelles.
Aside from different DNA, there isn't really much of a difference between animal cells and human cells. Human cells are an example of an animal cell.
Predominantly multicellular not in bacteria but in human body • Cell contains a nucleus and other membrane bound organelles not in bacteria but in human body • DNA occurs in a circular form in bacteria only
Production of human insulin from bacterial cells.
They are called antibiotics (meaning against life) and generally interfere in only a few specific chemical reactions, those found in bacterial cells but not human cells.
This is essentially because bacterial cells and human cells are very different. Both bacterial and human cells use chemicals called enzymes to build their walls. Penicillin is the right chemical "shape" to chemically stick to part of the bacterial enzyme. When it does this, it stops the bacterial enzyme from working properly and this makes the bacterial cell walls weak. The weakened cell wall cannot withstand the outside pressure, it breaks up and the bacterial cell dies. Human cells are made by different types of enzymes with a different chemical shape that penecillin is unable to stick to so it cant stop the human enzymes from working. The human cell walls are thus unaffected by it and they remain strong.
it has more human cells actually the human body has more bacterial cells. Although it may seem more likely that the human body would have more human cells than bacterial cells. -Vasillisa
a human cells have DNA and bacteria has plasmid
The difference is that human cells are made up of all different things but a computer cell is found on a circuit board.
protist cells have membranes, skin cells have walls
they all have numbers
Aside from different DNA, there isn't really much of a difference between animal cells and human cells. Human cells are an example of an animal cell.
cells of a multicellular organisms are specialized
billions of cells.
Their structure is one.A human lung cell is eukaryotic and part of the multicellular structure, the lung.Bacterial cells are prokaryotic and unicellular.Virus is a fragment of protein and nucleic acid that forms a infectious structure.
Predominantly multicellular not in bacteria but in human body • Cell contains a nucleus and other membrane bound organelles not in bacteria but in human body • DNA occurs in a circular form in bacteria only
mycoplasm which is a bacterial cell and human sperm cell are the smallest cells
Bacterial DNA is single strand. Human DNA in the nucleus is double helix. So, with human DNA, the DNA must first split apart before an RNA molecule can read it.
