List four features that are in prokaryotic cells but not eukaryotic cells
1. Prokaryotic cells lack a true nucleus. Instead, their genetic material is present in the form of a single circular chromosome that resides in the cytoplasm.
2. Prokaryotic cells do not have membrane-bound organelles like mitochondria, endoplasmic reticulum, Golgi apparatus, etc. However, they do possess non-membrane-bound organelles such as ribosomes, which are involved in protein synthesis.
3. Prokaryotic cells have a cell wall composed of peptidoglycan, a unique structural polymer that provides shape, support, and protection to the cell. In contrast, the cell walls of eukaryotic cells, if present, differ in composition (e.g., cellulose in plant cells or chitin in fungal cells).
4. Prokaryotic cells reproduce by binary fission, a relatively simple and rapid process by which one cell divides into two identical daughter cells. Eukaryotic cells, on the other hand, utilize various methods of cell division, such as mitosis and meiosis, which involve complex processes and multiple checkpoints.
Sure! Here are four features that are found in prokaryotic cells but not in eukaryotic cells:
1. Lack of membrane-bound organelles: Prokaryotic cells lack membrane-bound organelles such as mitochondria, chloroplasts, endoplasmic reticulum, and Golgi apparatus that are present in eukaryotic cells.
2. Circular DNA: Prokaryotic cells have a singular, circular DNA molecule called the nucleoid, which is not enclosed within a nucleus. In contrast, eukaryotic cells have linear DNA molecules enclosed within a nucleus.
3. Absence of histones: Prokaryotic DNA lacks histones, which are proteins that help in DNA packaging and organization in eukaryotic cells.
4. Smaller size: Generally, prokaryotic cells are much smaller in size compared to eukaryotic cells. They typically have a diameter of about 1-10 micrometers, whereas eukaryotic cells are typically 10-100 micrometers in diameter.
