Transcript of The Classroom

Cytoskeleton is like a classroom walls because the walls have struts, the beams in the sealing, and the floor. The cytoplasm is like the people, the air, and all the materials in a classroom. The cell membrane is like the walls of a classroom, it keeps the outside out and the inside in. Since the door is apart of that membrane it allows for transport across the membrane. The nucleus is like the teacher, because the teacher controls the class and directs the progress of the class. The mitochondria is like the candy in Miss. Zumbach's desk. The candy helps give the whole entire cell energy. It makes about 95% of the cells energy. The ribosomes are like the students of the room they do/make homework like ribosomes make proteins. The proteasome of the classroom is the turtle if our homework(proteins), are not correct then we can just get rid of the homework by feeding it to the turtle. The pathways in the classroom are like the centrioles because they help direct us through the classroom to our seats The Golgi apparatus is like the the file cabinets. The teacher stores them their until they need to be handed back to the class. The cytoskeleton gives the cells strength and form. The cytoplasm is a gel like substance that contains all the organelles. The cell membrane is what separates the inside of the cells from the outside. It also can allow for things to transport across the membrane. The nucleus controls operations and directs functions. Centrioles are small fibrous organelles shaped like cylinders found near the nucleus. They help move chromosomes when the cells divide. Ribosomes are small particles found in the cytoplasm and located in the endoplasmic reticulum. They help make proteins. Proteasomes digest damage proteins that can not be used. These proteins are then broken up into polypetides and amino acids. Mitochondria make the energy, (ATP), for the cell. Is Referred to as the powerhouse of the cell. The Endoplasmic reticulum is made up of the Smooth (ER) and the Rough (ER). The Endoplasmic Reticulum is important in protein synthesis and it folds proteins. It also transports cellular materials. The Golgi apparatus recieves the proteins from the (ER) and adds carbohydrates and lipids to the proteins and packages them in vesicles. They are stored until they need to be transported. Lysosomes are cell organelles that have digestive enzymes located within them. These organelles defend against bacteria and clean debris within the cell. They help maintain homeostasis within the cell. The custodians are like the lysosomes of a cell because they help pick of the trash that accumulates in the classroom. The Endoplasmic Reticulum is like a computer it can store information but it can also send material through email. From one computer to another.
