genbio1.3

• A single celled organism that does not have a nucleus. - prokaryote
• The bacterial nucleoid consists of the genetic material of the cell and the molecules that are bound to it.
• They do not have a nucleus, and their genetic material is not stored in the nucleus. - prokaryotes
• They have some organelles, but not many. - Prokaryotes
• All bacteria are prokaryotes.
• They are less complicated that eukaryotes. - Prokaryotes
• During the 14th century, 25% or % of Europe was killed by a killed by a bacteria called the Bubonic Plague, also called Black Death. This bacteria was spread through fleas and rodents.
• Bacteria are decomposers and without them all other organisms would not be able to survive.
• bacteria help digest our food.
• There are approximately ten times as many bacterial cells as human cells in the human body!
• We could not make cheese or yogurt without bacteria.
• Root exudates, sometimes called plant rhizodeposition products.
• Root exudates are organic compounds deposited (or exuded) by plant roots into surrounding substrates. These compounds are produced by plants using energy gained during photosynthesis. This phenomenon has long been recognized as a vital communication system between plants and their microbial communities
• Gut bacteria play an important role in human health, such as supplying essential nutrients, synthesizing vitamin K, aiding in the digestion of cellulose, and promoting angiogenesis and enteric nerve function.
• Eukaryote Cell - A more complex cell with a nucleus and many organelles.
• Eukaryote Cell -They all have a nucleus where the genetic material of the cell is stored.
• Eukaryote Cell -They have many organelles that work together to help the cell function.
• Eukaryote Cell - are much more complex then prokaryotic cells.
• Eukaryotic cells -They can be just one cell or can make up more complex multi-cellular organisms.
• All plants, animals, fungi, and protists are eukaryotic cells.
• Prokaryotic cells do not have a nucleus and eukaryotic cells do have a nucleus. This allows eukaryotic cells to make multi-cellular organisms and perform more complex functions.
• give the difference of prokaryotes and eukaryotes in terms of dna:

  
  

  the dna of prokaryotes is naked, circular and usually no introns while the dna of eukaryotes is bound to protein, linear and Usually has introns.
• give the difference of prokaryotes and eukaryotes in terms of organelles:

  prokaryotes have No nucleus, No membrane-bound and have 70s ribosome while the organelles of eukaryotes have a nucleus, Membrane-bound and have 80s ribosomes.
• give the difference of prokaryotes and eukaryotes in terms of reproduction:

  prokaryotes reproduce through binary fission and is Single chromosome (haploid) while eukaryotes reproduce through Mitosis and meiosis and is Chromosomes paired (diploid or more)
• give the difference of prokaryotes and eukaryotes in terms of size:

  the size of prokaryotes ranges from ~1 - 5 micrometer while eukaryotes ranges from ~10 - 100 micrometer
• give the similarities of eukaryotes and prokaryotes:

  have dna

  have ribosome

  have cell membrane

  have cytoplasm
