Study Notes
Cell Types and Structures
- Prokaryotic cells have a single membrane where all cellular reactions occur within the cytoplasm.
- Eukaryotic cells possess a nuclear membrane that surrounds the nucleus, differentiating them from prokaryotic cells.
- Prokaryotic cells are considered the earliest type of cells on Earth.
- A defining characteristic of prokaryotic cells is the lack of a nuclear membrane and organelles.
- Eukaryotic cells feature well-defined chromosomes located in the nucleus.
Differences Between Animal and Plant Cells
- A key feature unique to plant cells is the presence of a cell wall, which provides structure and support.
- Plant cells typically have a more regular shape due to their rigid cell walls, whereas animal cells are more irregularly shaped due to the absence of cell walls.
- Animal cells have no cell wall, allowing for a varied and more flexible cellular structure.
Organelles and Functions
- Mitochondria are the organelles responsible for energy exchange within many cell types, facilitating cellular respiration and ATP production.
- Lysosomes serve as digestion organelles, breaking down waste materials and cellular debris in a variety of cells.
Size and Complexity of Cells
- Generally, animal cells are larger than plant cells, but this can vary based on cell type.
- Prokaryotic cells are often simpler in organization compared to the more complex structure of eukaryotic cells, which include multiple organelles.
Common Misconceptions
- Not all prokaryotic cells are photosynthetic; this feature is exclusive to certain types of prokaryotes, such as cyanobacteria.
- Eukaryotic cells do contain organelles such as mitochondria and the Golgi apparatus, which are vital for various cellular functions.
