WebProkaryotic cells do not contain membrane-bound organelles like eukaryotic cells do. However, they have defined cell structures with important functions. These include the nucleoid, cell wall, capsule and nutrient storage compartments. Prokaryotic cells are much smaller than eukaryotic cells. WebFlagella are mainly composed of microtubules of the contractile protein tubulin. Multiple microtubules make up the flagella’s core. Lengthways, these microtubules extend. The axoneme is the name for the core. There are nine pairs of peripheral microtubule doublets organized radially in the axoneme. heili kirjastot lappeenranta

Recall that prokaryotes are divided into two different domains, Bacteria and Archaea, which together with Eukarya, comprise the three domains of life (Figure 3). WebFlagella are long, hairlike organelles that extend from the cell, permitting it to move. In prokaryotic cells, such as bacteria, the flagella rotate like the propeller of a motorboat.
