plant cells are a lot like the cafeteria in a factory. Chloroplasts help plant cells make food‚ much like cafeterias make food for the workers of a factory. In my marshmallow factory‚ there are two conveyor belts. The first represents the endoplasmic reticulum‚ because it packages the proteins‚ or marshmallows‚ into bags‚ or vesicles as it would be in a cell. The second conveyor belt is similar to the golgi apparatus‚ because it repackages the proteins into new vesicles‚ just like how the bags of

Question 1 1 out of 1 points Which of the following is true about “meiosis”? Select all that apply. Answers: Reproductive cells undergo meiosis Non-germ cells are reproduced Red blood cells undergo meiosis Number of chromosomes reduces by half in phase one Cell divides to produce four daughter cells Response Feedback: Meiosis occurs only in replicating gametes or reproducing cells. In phase one‚ the number of chromosomes is reduced by half but the chromatid pairs remain together. In phase

inside the city (control centre). Ribosomes- this is the industrial area of the city‚ creating building materials to extend and develop the city (proteins). Rough Endoplasmic Reticulum- these are couriers who collect the materials from the industrial site and take it to where it is needed (carry proteins). Smooth Endoplasmic Reticulum- another industrial site which creates packages to send and communicate with other cities (steroids). Mitochondria- the electricity generator which creates energy

mitochondrion‚ the Golgi complex‚ and the endoplasmic reticulum. The mitochondrion is the site of aerobic cellular respiration reactions that produce most of the cell’s ATP. The entry face of the Golgi complex accepts proteins from the rough ER. The medial cisternae form glycoproteins‚ glycolipids‚ and lipoproteins. The exit face modifies the molecules further‚ then sorts and packages them for transport to their destination. In the endoplasmic reticulum the rough ER synthesizes glycoproteins and

oxygen than normal‚ eventually beginning to cause the cells to die. Both intracellular organelles have membranes. The lack of ATP affects the plasma membrane and that special calcium ATPases had stopped moving calcium from cytosol into the endoplasmic reticulum of his cardiac muscle cells The breakdown of the membranes of these structures affect the functions of his heart cells because they keep everything in order‚ helps to keep organelles organized and enables the movement of the cell organelles

How would the breakdown of the membranes of these structures affect the function of josephs heart cells? Endoplasmic reticulum‚ the Golgi complex‚ the mitochondria and the lysosomes all have membranes in their structure. Whenever calcium levels rose to high the heart went in to a prolonged contraction‚ the lysosomes usually in the vesicles start to destroy its own

I:Ribosomes>Packager Just like the golgi apparatus the ribosomes package something inside the cell. There are many different types of packagers in a factory‚ ribosomes “package” protein. J:Endoplasmic Reticulum(smooth)>Electrician The electrician builds things that help the factory. The endoplasmic reticulum creates steroids and lipids to help the cell function.
