What else can I help you with?
Name one of the cell structures that is found in both a bacterial cell and an animal cell?
mitochondria, lysosomes, endoplasmic reticulum....
What are bacterial structures involved in the passage of DNA into or out of the cell?
Bacterial structures involved in the passage of DNA into or out of the cell include pili, which facilitate the transfer of DNA between bacterial cells through conjugation, and the cell membrane, which allows for DNA uptake during transformation or release during secretion. Additionally, some bacteria use specialized structures such as plasmids or phages to transfer genetic material between cells.
What structures are always found in bacterial cells?
Bacterial cells have several structures that are commonly found, including a cell wall for protection, ribosomes for protein synthesis, a plasma membrane for regulating what enters and exits the cell, and a nucleoid region containing the genetic material.
What are 6 main structures found in a bacteria cells?
There are not 6 but 5 main structures found in bacterial cells. They are DNA, cell membrane, ribosomes, surface layer and the cell wall.
What morphological structure responsible for bacterial motility?
flagellla
Which of the following would be best observed for a bacterial cell using phase contrast microscopy?
Internal structures and motility of the bacterial cell would be best observed using phase contrast microscopy. This technique enhances the contrast of transparent specimens like bacterial cells, allowing for detailed visualization of their internal structures and any moving parts such as flagella.
Bacterial cell Acidic dyes carry what charge?
They carry negative charge and are repelled by negatively charged cell structures. Basic dyes are opposite (carry positive charge) and are attracted to negatively charged cell structures.
Is there any similarity between bacterial cell wall and plant cell wall?
No, there is no similarity in bacterial cell walls and plant cell walls. They are different morphologically and also in chemical composition; plant cell walls are made up of cellulose, whereas bacterial cell walls are made up of peptidoglycan (also known as murein).
Does a Bacterial cell have only a cell wall?
No, bacterial cell also have phospholipid bilayers.
How is a plant cell different from a bacterial cell?
Plant cells have additional structures like chloroplasts, a large central vacuole, and a cell wall made of cellulose, which are not present in bacterial cells. Bacterial cells lack membrane-bound organelles like a nucleus and typically have a simpler structure compared to plant cells. Additionally, plant cells are eukaryotic, while bacterial cells are prokaryotic.
What is a cell wall mad of?
A cell wall is typically made of cellulose in plant cells and peptidoglycan in bacterial cells. These tough, rigid structures provide support and protection for the cell.
What cell is more complex a bacteria or an animal cell?
An animal cell is more complex than a bacterial cell. Animal cells have membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, while bacterial cells lack these structures. Additionally, animal cells have a nucleus that contains DNA, while bacterial cells have a nucleoid region that contains a single, circular DNA molecule.
