dense centre of the centrosome. Cytoplasm - the jellylike material outside the cell nucleus in which the organelles are located. Golgi body - (also called the Golgi apparatus or Golgi complex) a flattened‚ layered‚ sac-like organelle that looks like a stack of pancakes and is located near the nucleus. It produces the membranes that surround the lysosomes. The Golgi body packages proteins and carbohydrates into membrane-bound vesicles for "export" from the cell. Lysosome - (also called cell vesicles)

In this assignment I am going to be outlining the functions of the main cell components which include cell membrane‚ nucleus‚ chromosomes‚ cytoplasm‚ mitochondria‚ endoplasmic reticulum‚ Golgi apparatus and lysosome. There are two types of main cells which include eukaryotic and prokaryotic cells. A eukaryotic cell is a human cell. A eukaryotic cell possesses a clearly defined nucleus and has a nuclear membrane that surrounds the nucleus in which

Different Parts of a Plant Cell Plant cells are classified into three types‚ based on the structure and function‚ viz. parenchyma‚ collenchyma and sclerenchyma. The parenchyma cells are living‚ thin-walled and undergo repeated cell division for growth of the plant. They are mostly present in the leaf epidermis‚ stem pith‚ root and fruit pulp. Mature collenchyma cells are living‚ and provide stretchable support to the plant. Lastly‚ sclerenchyma cells (e.g. fiber cells) are hard‚ non-living and

same rules followed by all the other cells in the body. Two major theories were proposed regarding the nervous system: the reticular theory by Josef van Gerlach‚ and the neuron doctrine theory.1 Eventually‚ in 1873‚ an Italian scientist named Camillo Golgi discovered a staining technique that allowed the neurons and the fibers to be seen and later on‚ the Spanish scientist Ramon y Cajal further refined the technique. These two scientists made many contributions and eventually went on to share the Nobel

Golgi apparatus - The Golgi apparatus is composed of small membranous sacs‚ and is associated with the endoplasmic reticulum (ER). Though its function is still not entirely understood‚ it seems that proteins from the ER travel to the Golgi apparatus‚ where they are transformed and packaged into sacs before being moved to their final destination. 8.
