SC121 Unit 4 Assignment PART 1 Do not forget to add your references and citations. The references will go on the last page. 1. Why are cells important to the body? What do they do for us that makes them indispensable? (75-word minimum) Cells are important to the body because they are the building blocks of all living things ( What is a cell? - Genetics Home Reference - NIH. (n.d.) . The human body is made up of millions of cells. Each cell has a different function and does different things to help maintain life. Cells provide structure, get nutrients from foods, convert nutrients into energy, and carry out specialized functions. Each cell contains our DNA, and it can also make copies of itself. In a cell, there are different parts and each part has a different function that it does. Organelles are some parts of the cell and perform different things within the cell. Parts of a cell are cytoplasm, cytoskeleton, endoplasmic reticulum, Golgi apparatus, lysosomes and peroxisomes, mitochondria, nucleus, plasma membrane, and ribosomes. Cells are the smallest form of life without cells there would be no living things. They house everything that makes the proteins, chemicals, and signals in our body to make everything work ( Studying Cells. (n.d.). 2. Which cell organelle do you think would kill you the fastest if you lost it? Include an explanation of the normal functioning of the organelle in the body when it is present and connect that to what would happen if we lost it. Defend your logic and thoroughly explain. (75-word minimum) The organelle that would kill you the fastest if you lost it would be the mitochondrion. The mitochondria is the powerhouse of a cell. It has the most important function out of all of the organelles. It converts oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy “currency” of a cell that powers the cell's metabolic activities (3). This is called aerobic respiration which helps us breathe oxygen. This gives the cell energy and without energy
