Study Notes
The Cell: Prokaryotic and Eukaryotic
Cells are the building blocks of life, and they come in two main types: prokaryotic and eukaryotic. These cells differ in their structure, size, and complexity, which has a significant impact on their functions and the types of organisms they inhabit.
Prokaryotic Cells
Prokaryotic cells are simpler in structure and smaller than eukaryotic cells. They lack a nucleus and other membrane-bound organelles, which means they do not have a defined internal structure. Some key features of prokaryotic cells include:
- Size: Prokaryotic cells are typically smaller than eukaryotic cells, measuring between 0.1 to 3 micrometers in diameter.
- Nucleus: These cells do not have a nucleus or other membrane-bound organelles, which means they do not have a defined internal structure.
- DNA: Prokaryotic cells have circular DNA that is not confined to a nucleus.
- Reproduction: These cells reproduce asexually by binary fission, where the cell grows and splits in half, forming two identical daughter cells.
Prokaryotic cells are mostly found in bacteria, cyanobacteria, and archaea, which are unicellular organisms that inhabit various environments, such as soil, water, and the human body. They play a crucial role in ecological processes, such as decomposition and nutrient cycling, and are essential for human health and medicine.
Eukaryotic Cells
Eukaryotic cells are more complex and larger than prokaryotic cells. They have a nucleus and other membrane-bound organelles, which gives them a defined internal structure. Some key features of eukaryotic cells include:
- Size: Eukaryotic cells are typically larger than prokaryotic cells, measuring between 10 to 100 micrometers in diameter.
- Nucleus: These cells have a nucleus and other membrane-bound organelles, which gives them a defined internal structure.
- DNA: Eukaryotic cells have linear DNA that is confined to a nucleus.
- Reproduction: These cells reproduce sexually, which involves the fusion of two different sets of chromosomes from two parents to create a genetically diverse offspring.
Eukaryotic cells are found in multicellular organisms, such as plants, animals, and fungi. They are essential for the growth, development, and functioning of these organisms, as they perform various tasks, including energy production, protein synthesis, and cellular communication.
In conclusion, prokaryotic and eukaryotic cells differ in their structure, size, and complexity, which has a significant impact on their functions and the types of organisms they inhabit. Understanding these differences is crucial for understanding the fundamental principles of biology and the diversity of life on Earth.
