Question

can you give me a brief description about what is bacteria

Answer 1

BACTERIA

➡➡hey BUDDY HERE'S ur answer..

Bacteria are microscopic single-celled organisms that thrive in diverse environments. They can live within soil, in the ocean and inside the human gut. Humans' relationship with bacteria is complex. Sometimes they lend a helping hand, by curdling milk into yogurt, or helping with our digestion. At other times they are destructive, causing diseases like pneumonia and MRSA.

STRUCTURE

Bacteria are prokaryotes. The entire organism consists of a single cell with a simple internal structure. Unlike eukaryotic DNA, which is neatly packed into a cellular compartment called the nucleus, bacterial DNA floats free, in a twisted thread-like mass called the nucleoid. 

Bacterial cells also contain separate, circular pieces of DNA called plasmids. Bacteria lack membrane-bound organelles, specialized cellular structures that are designed to execute a range of cellular functions from energy production to the transport of proteins. However, both bacterial and eukaryotic cells contain ribosomes. These spherical units are where proteins are assembled from individual amino acids, using the information encoded in a strand of messenger RNA.

Answer 2

BACTERIA are primitive organisms consisting of single cells (prokaryotes, without a true nucleus) .
They have no chlorophyll and their body is not differentiated into parts like root, steam,leaves and flowers.
Some bacteria are used in medicine in production of antibiotics,serums and vaccines.
