Study Notes
Cell Types
- Prokaryotic cells lack a nucleus and membranous organelles, such as mitochondria, and have genetic material (DNA) scattered within the cytoplasm.
- These cells perform vital functions in the cytoplasm and cellular membrane and have ribosomes.
- Examples of prokaryotic cells include bacteria and blue-green algae.
Eukaryotic Cells
- Eukaryotic cells have membranous organelles, a real nucleus, and nuclear material is not scattered within the cytoplasm.
- These cells are more highly developed than prokaryotic cells and include cells of animals, plants, fungi, and protists.
- Eukaryotic cells have organelles in their cytoplasm, chromosomes (DNA and proteins) in the cell nucleus, and divide by mitosis.
Cytoplasm
- Cytoplasm is a semifluid matrix that fills the space between the cell membrane and the nucleus.
- All vital events occur in the cytoplasm of a living organism, and it generally forms a homogeneous transparent mass.
Mitochondria
- Mitochondria are ellipsoidal or cudgel-shaped organelles with a length of 2-3 μm and a diameter of 0.5 μm.
- They are the energy-generating organelles, where the energy released by breaking the chemical bonds of organic molecules is transformed into ATP.
