Study Notes
Characteristics of Eukaryotic Cells
- Eukaryotic cells are typically larger than prokaryotic cells and are found in multicellular organisms, although some single-celled eukaryotes exist.
- The defining characteristic of eukaryotic cells is compartmentalization, which means the cell is divided into different compartments or organelles.
Organelles in Eukaryotic Cells
- Organelles are membrane-bound compartments within a cell that have specific functions.
- The nucleus is a circular membrane-bound organelle that contains all the genetic material in the cell and is responsible for the name "eukaryotic".
- Mitochondria are the cell's power plant, where glucose is converted into ATP to provide energy for the cell.
- The endoplasmic reticulum is the site of protein synthesis, where mRNA is translated into proteins.
- The Golgi apparatus is responsible for processing and sending proteins to other parts of the cell or for secretion.
- Lysosomes and peroxisomes are recycling centers that break down cellular components and reduce reactive oxygen species.
Cell Division
- Eukaryotic cells divide by the process of mitosis, which is a more complex process than prokaryotic cell division.
- Mitosis involves the separation of the genetic material in the nucleus, followed by the division of the cytoplasm.
Comparison to Prokaryotic Cells
- Prokaryotic cells lack compartmentalization and have a single, large space where all cellular activities take place.
- Prokaryotic cells have their genetic material floating freely in the cytoplasm, rather than being contained in a nucleus.
- Prokaryotic cells divide by the process of binary fission, which involves copying the genetic material and then splitting the cell in two.
