Could a bacterial cell dispense with a cell wall if it had a capsule Why or why not?
A bacterial cell could potentially survive without a cell wall if it has a capsule, as the capsule provides a protective layer that can help maintain structural integrity and prevent desiccation. However, the cell wall plays a crucial role in protecting the cell from osmotic pressure and mechanical stress, which the capsule alone may not fully compensate for. Therefore, while a capsule can enhance survival under certain conditions, it cannot entirely replace the essential functions of a cell wall in maintaining cell shape and stability.
What possesses a spore capsule in mosses?
In mosses, the photosynthetic cell possesses a spore capsule. A good example is the polytrichum which has a capsule with a sterile jacket.
What is the adherence of a cell?
The capsule can be useful in medicine because
What microbe in cell wall keep it from drying out?
capsule
What is the purpose of emulsifying the bacteria in the capsule stain?
to stain the outside and the inside of the cell.. so the capsule appears transparent
Does a prokaryotic cell have a capsule?
Some prokaryotic cells have a capsule, which is a protective layer outside the cell wall. The capsule helps the cell adhere to surfaces, evade host immune responses, and protect it from desiccation and other environmental stressors. Not all prokaryotic cells have a capsule, as it is not essential for their survival.
What is the function of a slime capsule in a bacterial cell?
A slime capsule in a bacterial cell provides protection against desiccation (drying out), phagocytosis by immune cells, and chemical attack. It also helps the bacteria adhere to surfaces and form biofilms.
Do plant cells have slime capsule?
No, plant cells do not have a slime capsule. Slime capsules are typically found in certain bacteria, where they serve to protect the cell and help it adhere to surfaces. Plant cells have a cell wall made of cellulose, which provides structure and support, but they do not possess a slime capsule.
What is the rod shaped cell with no nuclear membrane and having a capsule exterior to it's cell wall is a member of?
The rod-shaped cell with no nuclear membrane and a capsule exterior to its cell wall is likely a bacterium. Bacteria are prokaryotic organisms, meaning they lack a true nucleus and other membrane-bound organelles. The capsule surrounding the cell wall of certain bacteria provides protection and helps the bacteria evade the host immune system.
Does Proteus vulgaris have a capsule?
Yes, Proteus vulgaris can have a capsule, which is a protective layer outside the cell wall. The presence of a capsule in P. vulgaris can contribute to its virulence and ability to evade the host's immune system.
What is a tiny capsule of genetic information that reprograms the machinery of a living cell?
virus.
What biological molecules can make up the bacterial capsule?
The cell capsule is a very large structure of some bacterial cells. It is a layer that lies outside the cell envelope of bacteria.
