The main form of asexual reproduction of diatoms are produced by binary fission. In asexual reproduction, undergo DNA replication of chromosomes caused to divide into two identical halves. This leads to the formation of two shells or teak. Each daughter cell receives one of the shells of stem cells and other organisms that reproduce asexually.
Diatoms, as all algae have a nucleus, cytoplasm, vacuoles and chromatoplasts as components of the cell. The wall of porous silicon with different motives in different places to passage of gases and nutrients into the cell. Diatoms are classified in groups of pine trees and the center. The group focuses on pinnate diatoms are round and elongated.
Reproduction of diatoms can be either sexual or asexual reproduction. All diatoms go through a phase of seeds or spores, as they say in the form of spores. Start with asexual reproduction in diatoms.
Asexual reproduction in diatoms
The main form of asexual reproduction of diatoms are produced by binary fission. In asexual reproduction, undergo DNA replication of chromosomes caused to divide into two identical halves. This leads to the formation of two shells or teak. Each daughter cell receives one of the shells of stem cells and other organisms that reproduce asexually. This makes little or mortgage frustule frustule to form more or epitheca. The parent cell is to divide the two daughter cells, growing out of the valve. Each daughter cell produces a new cell wall and daughter cells each receive a valve. Asexual reproduction leads to a reduction of the size of a daughter cell of average size. This ultimately leads to cell size that is only a third of its maximum size. This “reduction division” is a unique way of asexual reproduction in diatoms. Diatoms need to find the size of the original cell population of diatoms and therefore undergo sexual reproduction.
Sexual reproduction in diatoms
Diatoms are non-mobile and therefore the sperm flagella. Vegetative cells of diatoms are diploid (2n), as meiosis. The cells produce sexual gametes that fuse to form a zygote. Males produce sperm and females produce eggs. The cells of women have a tendency to bend and create an opening in the cell wall. This helps the sperm into the female cell. The sperm fertilizes the female cell. The fertilized egg is wrapped in an envelope like structure for the production of its own shell and core. Soon diatoms reach their adult size. The mother cell and the new way auxospores diatoms and act as if in a dormant stage called “spores. This allows the cells to survive long periods under difficult conditions. When these cells are favorable conditions for growth, they continue their diatom sexual reproduction.
* The word is derived from diatomaceous Greek dia meaning “through” and take “cut”. This is because the diatoms are cut in two of the frustule.
* Diatoms can live in freshwater and saltwater, and even survive in the soil.
* The cell wall made of silica called a frustule. The frustule has two halves overlap.
Diatoms are * hundreds of different shapes and sizes vary between 10 / 1000000 to 150 millionths of a meter.
* The diatomaceous mud at the bottom of water bodies are formed by the sedimentation of dead diatoms. You can read more about the facts of the diatomite
Scientists have found fossils of diatoms *, which is about 185 million years ago, Jurassic.
This was some information about diatom reproduction. Diatoms main consequences playback mode, ie, asexual reproduction in the first place. When the size of the cell population is greatly reduced, without sexual reproduction. I hope this article has helped you to understand the reproduction of diatoms.
