5 IntroductionThere are nine major structures (organelles) that make up a cell.Each organelle has a specific job to ensure the life of a cell
6 The Nucleus The nucleus is the largest cellular organelle in animals. The main function of the cell nucleus is to control gene exposition and mediate the replication of DNA during the cell cycle.
7 The NucleolusThe nucleolus is a structure found within the nucleus in which ribosomal RNA is transcribed.
8 Cell MembraneThe cell membrane surrounds the cytoplasm of a cell serving a function similar to that of skin.It contains a lipid (fat) bilayer and protein molecules on the outside of the cell
9 Golgi ApparatusThe Golgi apparatus is a cell structure mainly devoted to processing the proteins synthesized in the endoplasmic reticulumIt is composed of membrane-bound stacks known as cisternae
10 Endoplasmic Reticulum The Endoplasmic Reticulum forms an interconnected network of tubules, vesicles, and cisternae within cells. he endoplasmic reticulum serves many general functions, including the facilitation of protein folding and the transport of synthesized proteins in sacs called cisternae
11 RibosomeThe ribosome functions in the expression of the genetic code from nucleic acid into protein, in a process called translation.Ribosome are found on the outside of the Endoplasmic Reticulum
12 MitochondriaMitochondria are sometimes described as "cellular power plants" because they generate most of the cell's supply of chemical energy
13 CytoplasmThe Cytoplasm is the contents of a cell that is enclosed within the plasma membrane. The cytoplasm is the site where most cellular activities occur.
14 LysosomeThe Lysosome digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria
15 Question 1 Which Structure is found in the nucleus of the cell? -Gogli Apparatus-Nucleolus-Ribosome-Cytoplasm
16 Good Job!Remember that the Nucleolus is where ribosomal RNA is transcribed.
17 Question 2Which structure is responsible for removing worn out organelles?-Ribosome-Lysosome-Mitochondria-Nucleus
18 Good Job!Correct! Lysosomes remove foreign bodies from the cell as well as worn out organelles.
19 Question 3 Which organelle produces energy for the cell? Nucleus Cell membraneCytoplasmMitochondria
20 Good Job!Correct! Mitochondria produce ATP which the cell uses for energy.
21 Question 4 Where does most cellular activity occur? Nucleus Cell MembraneEndoplasmic ReticulumCytoplasm
22 Good Job!Good Job! The majority of cell activity occurs in the Cytoplasm.Only one more to go
23 Question 5_________ is the process of the expression of the genetic code from nucleic acid into protein.TranslationTranscriptionMutationModification
24 Good Job!Correct! Translation is the process of the expression of the genetic code from nucleic acid into proteins.
25 SummaryAn animal cell is made of many different organelles have specific functions within he cell.By working together all organelles create a system that create a healthy and living cell
