What Are We Made Of? Exploring Human Cells - Lesson 57

What exactly are we made of? We might think of our bodies as skin, bones, and blood, but what makes our skin, bones, and blood? Today we are zooming way in and discovering the busy cities inside our tiny cells. Here’s our trail map: What Is a Cell? What Are the 3 Main Parts of a Cell? How Is a Cell Like a City With Buildings and Workers? How Does Jesus Hold Everything Together?

He breathed the breath of life into the man’s nose, and the man became a living person.” Genesis 2:7 (NCV) “For in him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through him and for him. He is before all things, and in him all things hold together.” Colossians 1:16-17 (NIV) Terms Learned in This Episode: Cell Theory: The discovery made by Theodor Schwann and Mathias Schleiden in 1839 that all living things are made of cells and that cells are the building blocks of life. Cell Membrane: The outer layer of a cell, like a city wall, that keeps things in or out (and allows some things to pass through). Cytoplasm: Cyto means cell and plasm refers to liquid. Cytoplasm means cell liquid. Liquid inside a cell. Organ: A special part inside a body with an important job to do. Organelle : “Little organ.” Organelles are little things inside our tiny cells that have very important jobs to do. They are like our cells' own organs. Mitochondria : The organelle (“little organ”) inside our cells that acts as a power plant. The mitochondria turns nutrients from our food into energy called ATP, which powers our other cells and organelles. ATP : The energy produced by mitochondria in our cells to create more organelles and cells. Ribosome : The organelle (“little organ”) inside our cells that act like printers. Non membrane-bound organelles that are printing platforms. The ribosome “reads” copies of our DNA and prints them into proteins. Protein : Molecules in our bodies that create cells and perform many important jobs. Endoplasmic Reticulum (ER) : The organelle (“little organ”) inside our cells that act like print shop workers. They put final touches on the 3D-printed proteins in our cells. Lysosomes : The organelle (“little organ”) inside our cells that act like a cleanup crew. They rid cells of waste. They also act as recyclers, breaking down the food we eat into materials our cells can use.
