Prokaryotic Cells Vs Eukaryotic Cells Flashcards
What is the main difference in the nucleus between eukaryotic and prokaryotic cells?
Eukaryotic cells have a membrane-bound nucleus, while prokaryotic cells do not have a nucleus. Their DNA is located in a nucleoid region.
Compare the size of eukaryotic and prokaryotic cells.
Eukaryotic cells are generally larger (10-100 µm) compared to prokaryotic cells, which are smaller (1-5 µm).
How do eukaryotic and prokaryotic cells differ in their organelles?
Eukaryotic cells have membrane-bound organelles, such as mitochondria, the endoplasmic reticulum, and Golgi apparatus. Prokaryotic cells lack membrane-bound organelles.
What is the difference in ribosome size between eukaryotic and prokaryotic cells?
Eukaryotic cells have 80S ribosomes, while prokaryotic cells have smaller 70S ribosomes.
Compare the DNA structure in eukaryotic and prokaryotic cells.
Eukaryotic cells have linear DNA organized into chromosomes within the nucleus, while prokaryotic cells have circular DNA located in the nucleoid region.
Do both eukaryotic and prokaryotic cells have a cell membrane?
Yes, both eukaryotic and prokaryotic cells have a cell membrane, but the composition and structure can differ.
Compare the cell wall composition in eukaryotic and prokaryotic cells.
In prokaryotic cells, the cell wall is usually made of peptidoglycan. In eukaryotic cells, if a cell wall is present (e.g., in plants and fungi), it is made of cellulose or chitin.
What type of cell division is seen in eukaryotic and prokaryotic cells?
Eukaryotic cells divide by mitosis and meiosis, while prokaryotic cells divide by binary fission.
Do both eukaryotic and prokaryotic cells have flagella?
Yes, but eukaryotic flagella are complex and made of microtubules in a “9+2” arrangement, while prokaryotic flagella are simpler and made of the protein flagellin.
Compare the presence of plasmids in eukaryotic and prokaryotic cells.
Plasmids, which are small circular DNA molecules, are commonly found in prokaryotic cells. They are rare in eukaryotic cells and typically found in some yeasts and protozoa.
What kind of organisms are considered a Eukaryote?
Protists, Animals, Plants, and Fungi.
What do all cells have in common?
- Every cell contains a membrane that separates the inside of the cell from the outside environment. This is called the plasma membrane. Proteins in the plasma membrane control what molecules can pass across the membrane.
- The inside of the cell is filled with a watery, protein-rich goo called cytoplasm (also called
cytosol).
3.DNA inside the cell stores the instructions for making the cell’s proteins, and the cell contains the machinery necessary to translate the DNA instructions to make proteins.
4.The cell contains proteins that are capable of harvesting and using energy from energy-rich molecules.
What do Prokaryotic and Eukaryotic cells share in common.
Both have DNA, Ribosomes, Cytoplasm, Cell membranes, Cell wall ( most prokaryotic cells have a cell wall while some Eukaryotic cells have it, such as plant cells and Fugal cells).
What is different between Prokaryotic and Eukaryotic cells?
- Eukaryotic cells are more complex than Prokaryotic cells.
- Prokaryotic cells have no nucleus to contain their DNA, while Eukaryotic cells do.
- Prokaryotic cells have no Membrane-Bound Organelles, while Eukaryotic cells do such as the Nucleus, Mitochondria, Endoplasmic Reticulum, and the Golgi Apparatus.
