Organelles found in all cells are Ribsome, Cell Membrane, and Cytoplasm. For those who do not know, Cytoplasm is the fluid content of cells in which organelles float. Ribsome assembles proteins from raw materials, following dirictions from the Nucleus. A Cell Membrane surrounds the cell and controls the movement of materials into and out of the cell. ( A Nucleus regulates the production of proteins. It contains genetic material. )

What are the similarities between bacterial cells and human cells?
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
What are the compounds that kill bacterial cells without harming the cells of humans?
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.
Are human nerve cell found in prokaryotic or eukaryotic cells?
Human nerve cells are eukaryotic cells, just like every other human cell.
The human body is composed of prokaryotic cells?
This statement is not accurate. Prokaryotic cells are found in organisms like bacteria, while human cells are eukaryotic, meaning they have a true nucleus and other membrane-bound organelles. Eukaryotic cells are more complex than prokaryotic cells.
Explain why antibiotics are effective at killing bacterial cells but do not seem to have an impact on human cells eukaryotic cells Use at least two examples such as tetracycline erythromycin?
Antibiotics target specific structures or processes unique to bacterial cells that are not present in human eukaryotic cells. For example, tetracycline interferes with bacterial protein synthesis by binding to bacterial ribosomes, while erythromycin inhibits the bacterial ribosome's ability to make proteins. Since human cells do not have the same type of ribosomes or protein synthesis mechanisms, antibiotics like tetracycline and erythromycin do not affect human cells the same way they do bacterial cells.
Does the human body have more bacterial or human cells?
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
What cells organelles are found in plants but not in humans?
Plants have chloroplasts and cell walls, which are structures not found in human cells. Chloroplasts are responsible for photosynthesis, while cell walls provide structural support and protection for plant cells.
How are bacterial cell and human body cell similar?
Bacterial and human cells both have a cell membrane, cytoplasm, and genetic material (DNA). They both carry out essential metabolic processes for survival and reproduction. However, human cells are eukaryotic, meaning they have a nucleus and membrane-bound organelles, while bacterial cells are prokaryotic and lack these features.

Are bacteria cells the same as human skin cells?
No, bacteria cells are prokaryotic cells, meaning they do not have a nucleus or membrane-bound organelles, while human skin cells are eukaryotic cells with a nucleus and organelles. Additionally, bacteria cells are much smaller in size compared to human skin cells.

Why does penicillin not affect 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.
