What is the similarities and difference between the bacteria and human cells?
Both bacteria and human cells are made up of a cell membrane, cytoplasm, and genetic material, but bacteria lack membrane-bound organelles like the nucleus found in human cells. Bacteria have a simpler structure and are typically smaller in size compared to human cells. Additionally, human cells are eukaryotic, while bacteria are prokaryotic.
What is the difference between binary fission and conjuction in bacterial reproduction?
Binary fission is a form of asexual reproduction in bacteria where a single cell divides into two identical daughter cells. In contrast, conjugation is a process of genetic exchange between two bacterial cells through a sex pilus, allowing for the transfer of genetic material from one cell to another. This enables genetic diversity and adaptation in bacteria.
What does bacteria do in the process of conjugation?
In conjugation, bacteria exchange genetic material through a tube-like structure called a pilus. This allows them to transfer DNA, such as plasmids, between cells. Conjugation enables bacteria to acquire new traits, such as antibiotic resistance, and increase genetic diversity.
What is a tubular appendage found on some bacteria that allows transfer of DNA between bacterial cells?
A tubular appendage found on some bacteria that allows transfer of DNA between bacterial cells is called a pilus. Pili are composed of protein subunits and serve as a bridge for the transfer of genetic material during a process called conjugation. This enables bacteria to exchange DNA and acquire new genetic traits.
What are the two main differences between mitosis and meiosis?
The two main differences between mitosis and meiosis are the number of divisions and the genetic variation in the resulting cells. Mitosis involves one division and produces two identical daughter cells, while meiosis involves two divisions and produces four genetically diverse daughter cells.
What is the form of genetic exchange in bacteria that involves contact between two cells?
This is the exchange of plasmids between the cells.
What is the similarities and difference between the bacteria and human cells?

Bacteria have a simpler structure and are typically smaller in size compared to human cells. Additionally, human cells are eukaryotic, while bacteria are prokaryotic.
What are thick walled cells in which bacteria store genetic material called?
Thick-walled cells in which bacteria store genetic material are called endospores. Endospores form when bacteria are under stress and help the bacteria survive harsh conditions by protecting the genetic material inside.
What is the difference between binary fission and conjuction in bacterial reproduction?
Binary fission is a form of asexual reproduction in bacteria where a single cell divides into two identical daughter cells. In contrast, conjugation is a process of genetic exchange between two bacterial cells through a sex pilus, allowing for the transfer of genetic material from one cell to another. This enables genetic diversity and adaptation in bacteria.
What did fred griffith find to be true after his experiment with the S and R strains of bacteria?
Fred Griffith found that genetic information could be transferred between different strains of bacteria, specifically between the harmless R strain and the virulent S strain of bacteria. This led to the discovery of transformation, a process where genetic material is exchanged between bacteria.
Is bacteria sexual or asexual?
Bacteria can reproduce both sexually and asexually. Asexual reproduction includes binary fission, where a bacterial cell divides into two identical daughter cells. Sexual reproduction in bacteria involves genetic recombination through a process called conjugation, where genetic material is transferred between bacterial cells.
What are the differences between bacteria cells and plant cells?
Bacteria cells are prokaryotic, meaning they lack a nucleus and membrane-bound organelles, while plant cells are eukaryotic and contain both a nucleus and membrane-bound organelles. Plant cells have a cell wall made of cellulose, chloroplasts for photosynthesis, and a large central vacuole, which are not present in bacteria cells. Additionally, plant cells can perform photosynthesis, while bacteria cells cannot.
What are the major differences between bacteria and eukaryotic cells.?
man this stuff is hard, but try it first if it don't make any sense then leave it.
Which is a type of Virus out of Bacteria Capsid Bateriophage and Pilus?
Bacteriophage is a type of virus that infects bacteria. It uses its protein capsid to inject its genetic material into a bacterial cell and replicate. Pilus is a structure found on bacteria that can be used for conjugation, the transfer of genetic material between bacterial cells.
Identify the two kingdoms of bacteria?
The two kingdoms of bacteria are the prokaryotes and the eukaryotes. Prokaryotes can be identified by their small size and their lack of organelles. Eukaryotic cells are larger, more efficient cells, due to membrane infolding and the presence of organelles.
What does bacteria do in the process of conjugation?
In conjugation, bacteria exchange genetic material through a tube-like structure called a pilus. This allows them to transfer DNA, such as plasmids, between cells. Conjugation enables bacteria to acquire new traits, such as antibiotic resistance, and increase genetic diversity.
What cells like bacteria without a nucleus?
Prokaryotic cells lack a true nucleus, and bacteria are prokaryotic cells. They have a nucleoid region where their genetic material is found, but it is not enclosed within a membrane like in eukaryotic cells.
