differences between prokaryotic and eukaryotic cells

Eukaryotic have nuclues and membrane bound organelles. While prokaryotic do not have any of these.

Eukraryotic cells have a membrane bound nucleus and organelles whilst prokaryotic cells have free floating DNA with no nucleus

Prokaryotic cells have no membrane-bound organelles including a nucleus. The DNA of many prokaryotes can be found in a chromosomal loop of DNA or in plasmids.

Prokaryotic cells are single celled organisms such as bacteria and viruses. They do not have a nucleus but they contain DNA. Eukaryotic cells are present in multi-cellular organisms such as plants and animals and do contain a nucleus.

Prokaryotic cells are bascially bacteria. They are characterised by, among other things, the lack of a nucleus containing genetic material - instead the genetic material is distributed freely in the cell. Eukaryotic cells have the genetic material confined to a nucleus which is clearly visible under the microscope...

Prokaryotes:

• unicellular
• cell wall
• no membrane bound organelles
• DNA is short, circular and not associated with histones
• no introns
• 70s ribosomes
• no nucleus

Eukaryotes:

• multicellular
• plant cells contain cell wall
• membrane bound organelles
• DNA is long, linear and associated with histones
• contains introns
• 80s ribosomes
• nucleus

Eukaryotic cells have membrane bound organelles, such as mitochondria and chloroplasts and have their DNA within a nucleus. Prokaryotic cells do not have membrane bound organelles and have their DNA in the cytoplasm.

The main difference between eukaryotes and prokaryotes is that the latter is a unicellular organism such as a bacterium. Eukaryotes however are the cells that form multicellular organisms such as humans. From that, we establish that prokaryotes are much smaller. another important difference is that DNA is stored in the nucleus in eukaryotic cells but floats in the cytoplasm in prokaryotic cells. Moreover, many structures (organelles) exist in eukaryotic cells but not in prokaryotic cells such as the mitochondria and ribosomes.

Eukaryotic cells have membrane bound organelles such as mitochondria their DNA is within a nucleus, whereas prokaryotic cells do not have membrane bound organelles and their DNA is free floating within the cytoplasm.

Prokaryotic cells are Bacteria cells , like yeast. Their unicellular and their nucleus is not membrane bound

Eukaryotic cells include animal cells and plant cells. Their multicellular and membrane bound

Animal and plant cells are eukaryotic cells whereas bacteria and yeast cells are types of prokaryotic cells. There are a few main differences between eukaryotic and prokaryotic. One is the size, prokaryotic cells are much smaller than eukaryotic cells. Prokaryotic cells also always have a cell membrane made of peptidoglycan whereas only some types of eukaryotic cells have a cell membrane. Finally, the genetic material for eukaryotic cells are found within the nucleus however for prokaryotic cells the genetic material is found in the cytoplasm.

Hello Elizabeth,

Prokaryotic cells where the first to appear on Earth (like a prototype is the first of a phone or a car). Therefore they are simple cells eg Bacteria

Key differences - Pro have an outer Slime capsule, No nucleus but strands of DNA and Plasmids floating in the cytoplasm and Flagella for motility.

Hope this helps.

A prokaryotic cell has different genetic and cellular features in comparison to eukaryotic cells. For example, prokaryotic cells have a strand of DNA lying in the chromosome whereas eukaryotic cells have condensed chromosomes in the nucleus. Prokaryotes are always unicellular and most eukaryotes are multi-cellular.

Remember a simple difference, Prokaryotes doesn't have nuclear membrane and the organelles are dispersed in cytoplasm while eukaryotes have nuclear membrane and the cellular Organelles are present inside the membrane.
