Prokaryotic cells are larger than eukaryotic cells. But eukaryotic cells consist of a true nucleus enclosed by two membranes. RNA polymerases are a complex of five polypeptides. Prokaryotes contain three promoter elements: one is upstream to the gene, second is 10 nucleotides downstream to it, and the third is 35 nucleotides downstream to it while eukaryotes contain a much larger set of promoter elements including the TATA box. Alveoli are microscopic air sacs in the lungs of mammals. ! Their cells are smaller than eukaryotic cells. View the full answer. answer choices. Eukaryotes use active transport to move substances across the cell membrane, while prokaryotes use facilitated diffusion. The key difference between prokaryotic and eukaryotic cells is that eukaryotic cells have a membrane-bound nucleus (and membrane-bound organelles), whereas prokaryotic cells lack a nucleus. We review their content and use your feedback to keep the quality high. Both cell types contain a cell membrane. Prokaryotic cells have different characteristic features. Archaea and Bacteria reproduce through fission, a process where an individual cell reproduces its single chromosome and . It also contains many sites for initiation and termination codons. Which statement best Prokaryotes tend to have smaller cell sizes than eukaryotes. Transcribed Image Text: Which statement best compares the terms "coccus" and "bacillus" as applied to bacteria? C. The presence of membrane-bound organelles in eukaryotic cells indicates that they are more complex than prokaryotic cells. The similarities between prokaryotic and eukaryotic replication can be understood as follows: Both the replication processes occur before nuclear division. The mRNA of many types of bacteria and bacteriophage are polygenic, that is a single mRNA is transcribed by the several structural genes of an operon. Eukaryotic cells include: plants, animals, fungi and protists ( a very heterogeneous group that are neither animals, plants or fungi and are often single cell and small e.g., protozoa). Similarly, any wastes produced within a prokaryotic cell can . These tiny . 8. Moreover, prokaryotes do not contain a nucleus. 10. The cell in the figure is a prokaryote. On the other hand, eukaryotic cell division is the process of producing daughter cells in eukaryotes.

Which statement best compares a eukaryote and a prokaryote. They belong to the group of organisms Eukaryota or Eukarya; their name comes from the Greek εὖ (eu, "well" or "good") and κάρυον (karyon, "nut" or "kernel"). The embryos of the five species are similar in size. Eukaryotes have membrane-bound organelles, while prokaryotes have few specialized structures. Question 9 120 seconds Q. Cell Size. See Page 1. a) prokaryotic; absence of organelles. The former domain Prokarya, which consists only of bacteria . Breathing structures are similar among the young of the five species. It mainly occurs through mitosis and meiosis. Human genome code for about 40000 proteins. In eukaryotic cells, all the chromosomes are contained within the nucleus. d. Eukaryotic cells are more . 13 Which statement is incorrect regarding eukaryotic cells? We can compare prokaryotic cells and eukaryotic cells in following points: • The prokaryotic cells are simple and primitive type of cells whereas •Eukaryotic cells are complex and advanced cells. At 0.1-5.0 µm in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10-100 µm ( [Figure 2] ). how!cells!behave!intheir!environment . The five species have a common ancestor with these embryonic structures. Eukaryotes use flagella to move themselves through substances, while prokaryotes are not able to move. The key difference between prokaryotic and eukaryotic cells is that eukaryotic cells have a membrane-bound nucleus (and membrane-bound organelles), whereas prokaryotic cells lack a nucleus. b. Eukaryotic cells contain a nucleus whereas prokaryotes do not, and eukaryotes show greater compartmentalization that allows for greater regulation of gene expression. Both have a nucleus. Only very few proteins interacts with prokaryotic DNA. While multicellular organisms use organ systems to perform life functions, single-celled . The small size of prokaryotes allows ions and organic molecules that enter them to quickly spread to other parts of the cell. Prokaryotes were the only form of life on Earth for millions of years . Both eukaryotes and prokaryotes can transfer DNA using conjugation and fertilization. 2. These are equivalent to the origin of replication in E. coli. Most prokaryotes are unicellular and are either archaea or bacteria. A. 43. Prokaryotic transcription occurs in the cytoplasm. A eukaryotic cell is much smaller and has a diameter between 10 and 100 micrometers (µm). Eukaryotic cells are larger and more complex than prokaryotic cells found in . Similarities between Prokaryotic and Eukaryotic DNA Ø The DNA is double stranded and helical in both prokaryotes and eukaryotes. Eukaryotic cells are more complex than prokaryotes, and the DNA is linear and found within a nucleus. Mutations increase the genetic diversity in both prokaryotes and eukaryotes. Reproduction happens through the process of binary fission. 2. All plant, protist, fungal and animal cells are eukaryotes. Prokaryotic cells lack membrane-bound organelles, and eukaryotic cells contain membrane-bound organelles. B. Similarly, any wastes produced within a prokaryotic cell can . Eukaryotic cells are typically larger than prokaryotic cells, ranging from around 10 to 100 μm in diameter. Prokaryotic cells have only one organelle: the .
