Prokaryotuc and eukarytotic cell & endocrine and exocine glands - Essay ExampleProkaryotic cells only have a plasma membrane while eukaryotic cells have organelles with membranes such as nuclear membrane (Campbell and Farrell 15).No nucleus is present in prokaryotic cells but there is a nuclear region with the dish up of which, the cell takes all its controlling directions. In addition, prokaryotes also have a single molecule of deoxyribonucleic acid that is circular in shape. Nucleus is the most important and unique part of eukaryotic cells and maximum desoxyribonucleic acid of the cell is present in the nucleus and multiple molecules atomic number 18 present (Campbell and Farrell 16). In prokaryotes, desoxyribonucleic acid is regain in the nuclear region that does not have any membrane while in eukaryotes, DNA is enclosed in Nucleus covered by nuclear envelope (Black 80).Cell division in prokaryotic cells takes place through binary fission while in eukaryotic cells, reproductio n is with the processes of mitosis and meiosis. In prokaryotic cells, only asexual reproduction takes place while in eukaryotic cells, asexual as well as sexual reproduction take place (Black 80). Prokaryotes as well as eukaryotes advise be autotrophic (generating food themselves) as well as heterotrophic (getting food from other sources). Examples of prokaryotes argon bacteria while plants and animals can be taken as examples of eukaryotes.Human body contains a arrangement called endocrine system containing glands responsible for discharging their secretions. Endocrine glands are responsible for discharging their secretions within the body while exocrine glands secrete on the body surface. Endocrine glands secrete internally while exocrine glands secrete externally. The secretions that are secreted by the glands are the hormones (Clark 229).Exocrine glands secrete with the support of ducts while in endocrine glands, no transparent ducts are present for transferring secretions du e to which, endocrine glands secrete
