An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or facilitating chemical reactions through the introduction of electrical energy. A common example of an electrochemical cell is a standard 1.5 - volt cell meant for consumer use. This type of device is known as a single galvanic cell. A battery consists of one or more cells, connected in either parallel or series pattern.
Most of the DNA in eukaryotes is found in the nucleus, while prokaryotes, lacking a nucleus, have their DNA loose in the cytoplasm. Explanation: In eukaryotes, the genomic DNA, which makes up most of the cells DNA, is contained in the nucleus. There is additional DNA in the cells mitochondria, and still more in the chloroplast if it is a plant cell, but it is a very small amount.
All the animals, plants, and fungus are eukaryotic organisms; nuclear envelope is the most defining character for all eukaryotic organisms. In eukaryotes, mostly DNA is stored inside the cell nucleus, but some are found within the organelles such as chloroplasts and mitochondria. In eukaryotes, DNA is found mostly in the cell nucleus, but some are in mitochondria and chloroplast while, in prokaryotes, it is found in the cytoplasm. â¢ DNA usually occurs as circular chromosomes in Prokaryotes while it is linear chromosomes in Eukaryotes.
