Which organisms never have cells with cell walls?
Animal cells do not have cell walls.Plant cells have walls containing cellulose, fungal cell walls contain chitin, and bacteria have walls containing peptidoglycan.
What is the difference between a capsule and a slime layer?
A capsule is a well-defined, dense layer that is firmly attached to the cell wall of some bacteria and protects the cell from phagocytosis by immune cells. A slime layer, on the other hand, is a looser and more diffuse layer of extracellular polysaccharides that helps bacteria adhere to surfaces and form biofilms.
What are two types of glycocalyx found on bacteria?
The two types of glycocalyx found on bacteria are capsule and slime layer. Capsules are dense, well-defined structures composed of polysaccharides that provide protection and help bacteria evade the immune system. Slime layers are looser, diffuse layers of polysaccharides that aid in attachment to surfaces and formation of biofilms.
What are the main subgroups of protists?
The main subgroups of protists include algae, protozoa, and slime molds. Algae are photosynthetic protists, while protozoa are heterotrophic protists that can be classified based on their mode of locomotion. Slime molds are protists that can exist as single cells or form multicellular structures.
When the amoebalike cells of acellular slime molds fuse they form structures with many nuclei called?
When the amoebalike cells of acellular slime molds fuse, they form structures with many nuclei called plasmodia. These structures allow the slime mold to move and feed as a single entity, despite being made up of many individual cells.
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.
Is there a slime capsule in animal cells?
No, slime capsules are not found in animal cells; they are typically found in certain types of bacteria. Animal cells do not produce slime capsules as a means of protection or survival within their environment.
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.
What are the organelles of prokaryotic cells?
Cell membrane, cell wall, slime capsule, flagellum, 70s ribosomes, plasmid, cytoplasm, circular DNA.
What are the bacteria producing slime layer?
capsule

What does the slime capsule do?
The slime capsule is a protective layer that surrounds some bacteria to help them survive in harsh conditions. It can help bacteria resist desiccation, protect them from predators, and facilitate movement in certain environments.
What is the slime layer that surround gram negative bacteria and keeps them from taking up purple stain?
capsule
What is the slime layer gram negative bacteria and keeps them from taking up purple stain?
capsule
What is the similarity between slime layer and capsule bacteria?
Both slime layer and capsule are outer protective layers found in some bacteria. They help bacteria adhere to surfaces and protect them from desiccation, predation, and the host immune system. The main difference is that capsules are more organized and tightly bound than slime layers.
What is the Slime layer that surrounds gram-negative bacteria and keeps them from taking up purple stain?
capsule
