List 4 cell organelles and their function (what they do) in the eukaryotic cell.


Cell organelles in Eukaryotic cell:                                                       Eukaryotic cell has many cell organelles which are bounded by double membrane, a single membrane or having with out bounded membrane. I will enlist only  four according to question requirement. 1. Chloroplast:                   It is s double membrane bound organelle present only in plant cells. It contain a green pigment called chlorophyll. Function:               Chloroplast is the site where photosynthesis occurs in the presence of sunlight and glucose is prepared  2. Mitochondria:                     It is found in all eukaryotic cells. It iis a double membrane bound organelle.  Function:                   Mitochondria is known as power house of cell. It is the site where cellular respiration occurs and ATP is produced  by breakdown of glucose in the presence of oxygen. 3. Endoplasmic reticulum:                                        It is a network of channels extended through out the cell, connecting nuclear membrane with plasma membrane. endoplasmic reticulum having ribosomes attached are called rough endoplsmic reticulum. While some endoplamic reticulum are free of ribosomes these are smooth endoplasmic reticulum.  Function:            a. It is the site where protein synthesis  occurs, smooth endoplasmic                                reticulum is involved in lipid metabolism.            b. It also detoxify the effect of harmful substances.            c. It also help in nerve impulse transmission. 4. Nucleus:                      It is one of the most important cell organelle present in the center in animal cell while at one side in plant cell due to the presence of large vacuole. It contains chromosomes. Function:               Nucleus control all activities of a cell. It contains DNA that acts as a hereditary materials, transfer characters from parents to offspring.
