1 When struck, crystal produces a musical ring. 2  Glass does not. 3  If you wet your finger and run it around the rim of a crystal glass it will also produce a musical tone. 4  Crystal can be worked thinner than glass, so if the rim of a piece is exceptionally thin it's probably crystal.
Nucleus: They are the membrane bound organelles, which are found in all eukaryotic cells. It is the very important organelle of a cell as it controls the complete activity of a cell and also plays a vital role in reproduction.t forms a connection between nuclear envelope and the cell membrane of a cell. Mitochondria: They are rod shaped organelles, plays an important role in releasing energy and they are the powerhouse of a cell. In plant cell, they are the sites of cellular respiration.
A major organelle in most eukaryotic cells is the structure of membrane-bound sacs called the Golgi apparatus (or Golgi body, Golgi complex, dictyosome).It acts to process and package the macromolecules such as proteins and lipids that are synthesized by the cell. It has been likened to the cell's post office. major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.
