cells, Eukaryotic and Prokaryotic

• there are two types of cells Eukaryotic and prokaryotic cells
• Prokaryotic cells

  • Prokaryotic cells do not contain a nucleus.
  • Prokaryotic cells are 0.1 - 5.0 micrometres in size. This is much smaller than eukaryotic cells.
  • A prokaryote is an organism made up of prokaryotic cells.
  • Bacteria are prokaryotes.
• Eukaryotic cells contain a nucleus.
• • Eukaryotic cells are found in plants, animals, fungi and protists (single-celled organisms that don’t fit other categories).
• Eukaryotic cells are 10 - 100 micrometres in size.
• • A eukaryote is an organism made up of eukaryotic cells.
• • Prokaryotic cells do not contain a nucleus.
• • Prokaryotic cells are 0.1 - 5.0 micrometres in size. This is much smaller than eukaryotic cells.
• • A prokaryote is an organism made up of prokaryotic cells. Bacteria are prokaryotes.
• Eukaryotic cells can be up to 1,000 times larger than prokaryotic cells.
• Some prokaryotic cells contain small rings of DNA called plasmids. These plasmids can replicate and move between cells so that genetic information can be shared.
• Prokaryotic cells do NOT contain mitochondria (where respiration takes place) or chloroplasts (where photosynthesis takes place).
• Prokaryotic cells do not have a nucleus (where DNA is stored). Instead, most of their genetic material is stored in a single DNA loop in the cytoplasm (watery jelly that fills the cell).
• All eukaryotic cells contain a cell membrane, cytoplasm and a nucleus. Prokaryotic cells do not have a nucleus. Instead, their genetic material is stored in a single DNA loop in the cytoplasm.
