Is Golgi apparatus found in prokaryotic or eukaryotic cells?
In this space reside DNA, RNA, ribosomes and other molecules. Prokaryotes lack a defined nucleus (which is where DNA and RNA are stored in eukaryotic cells), mitochondria, ER, golgi apparatus, and so on. In addition to the lack of organelles, prokaryotic cells also lack a cytoskeleton.
Cells of Bacteria: The cells of bacteria are different from those of plants and animals in many ways, the most obvious of which is that bacteria lack a nucleus and other membrane-bound organelles (except ribosomes). Unlike animals and plants, bacteria have pili, flagella, and most have a cell capsule.
- Some bacteria have a single, tail-like flagellum or a small cluster of flagella, which rotate in coordinated fashion, much like the propeller on a boat engine, to push the organism forward. The hook: Many bacteria also use appendages called pilli to move along a surface.
- Bacteria (singular: bacterium) are a major group of living organisms. Most are microscopic and unicellular, with a relatively simple cell structure lacking a cell nucleus, and organelles such as mitochondria and chloroplasts.Bacteria are the most abundant of all organisms.
- Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral(spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. SHAPES OF BACTERIA: Cocci (from kokkos meaning berry) are spherical or oval cells.
Ribosomes can exist free in the cytoplasm but are usually found attached to rough endoplasmic reticulum (RER). The ribosomes in eukaryotic cells are made in the nucleolus - which is inside the cell's nucleus. That is, the ribosomes in prokaryotic cells (i.e. bacterial cells) are the smaller (70 S) type.
- Introns are well known in bacterial and archaeal genes, but occur more rarely than in most eukaryotic genomes. In my biochemistry course we learned that bacteria have no introns and eukaryots nearly always have them.
- The cells of all prokaryotes and eukaryotes possess two basic features: a plasma membrane, also called a cell membrane, and cytoplasm. However, the cells of prokaryotes are simpler than those of eukaryotes. For example, prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus.
- The major differences between Prokaryotic and Eukaryotic cells are that prokaryotes do not have a nucleus as a distinct organelle and rarely have any membrane bound organelles [mitochondria, chloroplasts, endoplasmic reticulum, golgi apparatus, a cytoskeleton of microtubules and microfilaments] (the only exception may
