Do all bacteria have folded mesosomes?
Not all bacteria have folded mesosomes. Mesosomes are structures that were once thought to be involved in various cellular processes, but their existence and function are debated among scientists. Many modern studies suggest that mesosomes may be artifacts of the electron microscopy process rather than distinct, functional structures in all bacteria. Therefore, while some bacteria may exhibit similar structures, they do not universally possess folded mesosomes.
Who is possessed only by some bacteria not by eukaryotes?
Plasmids are small, circular DNA molecules that are often found in bacteria but are not typically present in eukaryotes. These extrachromosomal elements can carry genes that provide bacteria with advantageous traits, such as antibiotic resistance. While some eukaryotic cells can harbor similar structures, they do not possess plasmids in the same way that bacteria do. Thus, plasmids are primarily associated with prokaryotic organisms.
Which is true about bacteria a) all bacteria cause diseases in animals b) bacteria have complex internal structures c) bacteria help break down some foods. D) all bacteria are spiral in shape?
The correct statement is c) bacteria help break down some foods. Many bacteria play essential roles in digestion, particularly in the human gut, where they help break down complex carbohydrates and synthesize vitamins. While some bacteria can cause diseases, not all do, and bacteria generally have simpler internal structures compared to eukaryotic cells. Additionally, bacteria come in various shapes, including rod, cocci, and spiral, so not all are spiral in shape.
What are heat resistant structures in bacteria?
Heat-resistant structures in bacteria include endospores, which are dormant, tough structures that can survive extreme conditions like high temperatures. Endospores are formed by some bacteria as a defense mechanism to protect their genetic material. They allow bacteria to withstand harsh environments and continue to exist in unfavorable conditions.
What structures do some bacteria have to help them move in watery environments?
Some bacteria possess structures called flagella, which are long, whip-like appendages that rotate to propel the bacteria through watery environments. Additionally, some bacteria may have pili or fimbriae, which can help in adhesion and movement across surfaces. These structures enhance the bacteria's ability to navigate their aquatic surroundings and access nutrients or evade predators.
What are the Five major structures found in all bacteria?
The five major structures found in bacteria are capsule,ribosome,nucloid,flagella pilli,cytoplasm and pilus also
What cover the outside of all prokaryotes?
Along the surface of some bacteria are structures called pili that help bacteria adhere to surfaces

What kingdom includes all prokaryotes except archaebacteria?
The kingdom that includes all prokaryotes except archaebacteria is the Kingdom Bacteria, also known as Eubacteria. These organisms have simple cell structures and lack a membrane-bound nucleus.
Are bacteria multicellar?
No, bacteria are not multicellular; they are unicellular organisms. Each bacterium consists of a single cell, which performs all necessary life functions. While some bacteria can form colonies or clusters, they do not have the specialized tissues and structures characteristic of multicellular organisms.
What are the 5 basic parts of bacteria?
In terms of structure,5 basic parts are:cell membranecytoplasmic matrixnucleoidplasmidribosomesthese structures are present in all bacteria so they are the essential(basic) components of bacteria
What features are possessed by seeds that are dispersed by wind?
This feafeatures are possessed by some plants use wind as the way of seed dispersal . they produce large numbers of seed which are very light and contain feather like structures such that they can have large distances
A bacteria can be classified as a eukaryote?
No, bacteria are prokaryotes, not eukaryotes. Eukaryotes have membrane-bound organelles and a nucleus, while prokaryotes do not have these structures.
