The nucleolus of a cell is part of the production of ribosomes and contains the cell's RNA, one of the vital building blocks that tells the cell what it is. Ribosomes generate proteins that are needed for the basic functions of living cells. Cells have a roughly spherical shape, which coincides with the rounded shape of the nucleolus.Know More
Thanks to the presence of a nucleolus, cells can generate and interact with proteins that help them generate more cells and perform other complex tasks. Proteins are large biological molecules and are part of the process of replicating DNA, making them vital in creating the building blocks of life.
Nucleoli are found only in eukaryotic cells and are a vital part of the entire structure. The structure of this cell component was first theorized properly in 1964 when studies of a species of frog yielded insightful results. Experts discovered that cells that lacked a nucleolus in their structure were not capable of life in the case of these frog eggs. Only the cells that contained a nucleolus seemed to be able to produce the necessary components to ultimately grow into a healthy new frog. The scientists who discovered this were John Gurdon and Donald Brown.Learn more about Cells
The nucleus is the part of the cell that contains most of the genetic information found in cells. Genetic information is stored within a DNA molecule, tightly wound into a structure known as a chromosome. A tiny amount of genetic information is found in the mitochondria, outside of the nucleus.Full Answer >
Cell division is part of the cell cycle, and it is caused either by binary fission or as part of a multiple-phase cycle. Binary fission is the method by which prokaryotic cells divide. Eukaryotic cells use the three-phase cycle commonly referred to as mitosis.Full Answer >
In a voltaic cell, the oxidation reaction occurs in the anode; this means the metal loses its electrons in this part while the other metal undergoes the reduction reaction and gains the anode's lost electrons. This redox reaction involves the transfer of electrons from one electrode to another.Full Answer >
The part of the plant cell that gives the plant its green color is an organelle called the chloroplast. Inside the chloroplast there are pigment molecules called chlorophyll, which is the substance that gives plants their green color.Full Answer >
