Microorganisms can be divided into two groups:
1. Archea
• Archea are prokaryotic unicellular organisms without cell nucleus or other membrane bound-organelles.
• Their membrane is built from ether lipids, which differs them from bacteria’s cell membrane.
•
2. Bacteria
• Bacteria are also unicellular prokaryotic organisms.
• Bacterial cell membranes are made from phosphoglycerides with ester bonds. Bacterial genome is in a form of circular chromosome.
• They reproduce by binary fission or by budding.
Besides, prokaryotes (Archea and Bacteria) a large number of eukaryotes are also microorganisms. Unicellular eukaryotes contain organelles such as the cell nucleus, the Golgi apparatus and mitochondria. Usually, they reproduce asexually by mitosis. An example of eukaryotic microorganism is Protist.
1. The centriole forms the pole of the spindle apparatus chromatin
2. The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membranes which surrounds the nucleus
3. Haploid
4. Chromatids
5.Meiosis
6. Spindle Apparatus
7. Anaphase
8. Mitosis
9. Chromatin
10. Interphase
The two components of a 5-methyluridine are thymine and ribose pentose sugar. Here thymine will joined with the ribose pentose sugar . Thymine is the nucleic acid . There are two types of nucleic bases . Purine and pyramidine . Hence purine comes under pyramidine. Thymine is represnted by T symbole.
Answer:
myelinated fibers
Explanation:
The basis for differentiation between gray matter and white matter in the cns is the presence of myelinated fibers in white matter
