Where are we going with this? The information on this page should increase understanding related to this standard: Evaluate comparative models of various cell type…Evaluate eukaryotic and prokaryotic cells.
- All living organisms are made up of cells.
- Cells are the basic unit of life.
- All cells come from pre-existing cell.
If an organism has eukaryotic cells, it is said to be a eukaryote. Alternately, if an organism has prokaryotic cells, it is said to be a prokaryote.
- Eukaryotic cells have a nucleus and membrane-bound organelles.
- Eukaryotic cells have ribosomes, which are organelles that make proteins.
- Eukaryotic cells are larger and more complex than prokaryotic cells.
- Based on having eukaryotic cells, some organisms are classified as eukaryotes.
- DNA is housed in the nucleus in structures called chromosomes (chromatin).
- All prokaryotes have a cell wall.
- Prokaryotic cells also have ribosomes.
- Prokaryotic cells are smaller and less complex than eukaryotes.
- Organisms made up of prokaryotic cells are called prokaryotes.
- Prokaryotes are usually unicellular, although there is some debate that they can be multicellular.
- DNA is floating freely in one chromosome and is circular in shape.
This process continued until the modern-day eukaryote evolved with many organelles.
