Comparing and Contrasting Prokaryotic and Eukaryotic Cells
Transcript of Comparing and Contrasting Prokaryotic and Eukaryotic Cells
All cells contain DNA whether in or out of nucleus
All cells have a cell(plasma) membrane
All cells contain cytoplasm These cells are seperated into 2 categories:
Prokaryotic and Eukaryotic Cells Another big difference between these two types of cells is that prokaryotic cells came first on planet Earth, but eukaryotic came later through evolution. Although we know the first cells on earth were prokaryotic scientists still do not know where the first cell came from. The main difference between these two types of cells is that prokaryotic cells have genetic material that is not contained by a nucleus(no organelles) and eukaryotic cells have genetic material that is contained by a nucleus(have organelles). Big Difference Between Prokaryotic and Eukaryotic Cells Unicellular vs. Multicellular Prokaryotes are unicellular, which means they are single-celled organisms, while on the other hand eukaryotes are multicellular, which means they have more than one organism in a cell which all work together. Organization and Organelles The BIG and the small Prokaryotic cells are smaller and very simple being only 1 to 5 um large, but Eukaryotic cells are much bigger ranging from 10 to 100 um large, being much more complex. But both are simalar in a way because only objects that are about 0.5 mm are visible to the human eye. Examples of Prokayotic and Eukaryotic Cells The biggest example of a prokaryotic cell is bacteria. Some examples of things that are eukaryotic is plant and animal cells, fungi, and lastly protists. Cell Structure All cells look different. Also in some cells there might be more of one thing than another.For example muscle cells might have more mitochandria for energy. And lastly DNA tells cells what to do/function Overview of Two Cells Prokaryotic Eukaryotic Large and complex
Contain a nucleus
Contain dozens of internal structures(have organelles)
Can be single or multicellular
EX.Plant and animal cells, fungi, and protists Small and simple
Lack a nucleus
Lack organization and organelles

A reason why prokaryotic and eukoryotic are the size they are is due to what is held inside them. For example, prokaryotic cells are smaller because they have no organelles, and eukaryotic cells are larger because they are more complex and contain many organelles.
