Name______________________ Sim Cell: Scannable Objects Scavenger Hunt - Answer Key Use the Scan Function in Sim Cell to complete the table below to keep track of all the objects you encounter in the game! Scannable Object ATP Definition An ATP molecule is a packet of energy, like a battery. When an organelle needs energy to function, it uses ATP. ATP is made by the cell’s powerhouse, the mitochondrion. Mitochondria take in oxygen and glucose molecules. These molecules react inside the mitochondria to make ATP. Aquaporins are tiny pumps that push water into the plant cell’s Vacuole. They are powered by ATP. Aquaporin Carbon Dioxide Cell Membrane Carbon dioxide is a molecule created by animals and used by plants to create energy. It’s created as a byproduct of ATP production in the mitochondria. Plant cells use it in sunlight powered chloroplasts to create glucose and oxygen for use by mitochondria. In the animal cell it is treated as a waste and escapes through gaps in the cell membrane. The cell membrane is a thin, flexible layer that protects and separates the cell from the environment. The cell membrane acts like a security guard. It tries to stop viruses, poisons and waste from getting into the cell, while letting in molecules that the cell needs. The centrosome is the organelle that makes and organizes microtubules, long tubes that give the cell structure. By making microtubules, the centrosome helps support the cell’s shape. Centrosome Scannable Object Definition The chloroplast is an organelle that takes in sunlight and carbon dioxide. It uses them to make oxygen and glucose. Chloroplast Chromatin Chromatin is a combination of DNA and proteins. It helps package the DNA so that it fits within the nucleus. It also forms chromosomes when the cell divides. A chromosome is a single segment of DNA coiled and packed into a smaller, denser shape. Chromosomes contain all of the information about the cell in one tiny segment. Chromosome DNA takes this form when the cell divides into two ‘daughter’ cells. Each daughter cell needs to have the original cell’s information. So, each one gets copies or pieces of chromosomes. The cytoskeleton is the skeleton of the cell. It gives the cell shape. Cytoskeleton DNA Endoplasmic Reticulum DNA is a set of instructions for everything the cell does. These twisting strands are the foundation of all life on Earth. DNA has to stay protected inside the nucleus. But other parts of the cell need its instructions, so the cell needs to make copies of its DNA. The copies are called RNA. One kind of RNA is called messenger RNA, or mRNA. mRNA carries the instructions for making proteins that fix damaged cell parts. mRNA must be brought outside the nucleus to the ribosomes. Using the mRNA instructions, the ribosomes build proteins. This process helps the cell do simple things like repair and defend itself. The endoplasmic reticulum is the cell’s transport system. It transports proteins wherever they’re needed in the cell. It doesn’t make proteins, though. Proteins are made by ribosomes. Scannable Object Extracellular Matrix Definition The extracellular matrix exists outside cells, connecting them together and maintaining their structure. It can also take part in communication between cells. Glucose is a molecule the cell uses for food. Most of the time, glucose floats around inside the cell. Glucose Golgi Apparatus Glucose can be used to help make energy. To make energy, glucose and oxygen need to react inside a mitochondrion. The mitochondrion will then pump out ATP, the cell’s energy source. The Golgi apparatus is the organelle that produces lysosomes. It’s also used for sorting and packaging molecules. To build a lysosome, the Golgi apparatus needs energy in the form of ATP. The Nanobot can bring ATP from a mitochondrion to the Golgi apparatus. Scan a mitochondrion for information about making ATP. A lysosome is a virus-killer. It contains enzymes that dissolve viruses and unwanted cell parts. A lysosome will destroy any virus it touches. Lysosome Microtubule Mitochondrion Microtubules are long tubes that support the cell. They are part of the cytoskeleton, which keeps the cell from losing its shape. They also help transport organelles and other materials around the cell. The mitochondrion is the cell’s powerhouse: it makes energy. The packets of energy it makes are called ATP. To make energy, mitochondria need oxygen and glucose. These molecules float freely around in the cell. The Nanobot can collect these molecules and shoot them into the mitochondria. They react inside, and energy comes out in packets of ATP. The Nanobot can carry ATP to other parts of the cell. When mitochondria make ATP, carbon dioxide molecules come out too. Carbon dioxide is a byproduct, though, so the cell releases it through an opening in the cell wall. Scannable Object Nuclear Envelope Nucleus Oxygen Protein Definition The nuclear envelope is the outer wall of the nucleus. It separates the nucleus from the rest of the cell. Most importantly, it keeps the cell’s DNA locked up safely inside. The nucleus functions kind of like the cell’s brain. It holds DNA, which is a set of instructions for everything the cell does. The DNA itself never leaves the nucleus, but it can be copied. Copies of DNA are called mRNA. mRNA can travel outside the nucleus to other parts of the cell. Oxygen is a molecule the cell uses to make energy. Energy is made by an organelle called the mitochondrion. When the cell needs to make energy, oxygen has to enter the mitochondrion along with another molecule called glucose. Inside the mitochondrion, oxygen and glucose react chemically. Packets of ATP then come out of the mitochondrion. Proteins are large molecules that can be used for several different tasks. One of their most important jobs is to repair damaged organelles. To make a protein, the cell needs to get instructions from its DNA. DNA can be copied into strands of mRNA, which then get passed to the ribosomes, the cell’s construction crew. mRNA gives the ribosomes the instructions they need to make proteins. RNA polymerase is a molecule found only in the nucleus. It helps the cell copy its DNA. RNA Polymerase Ribosome Each DNA strand has a transcription initiation complex somewhere along its length. RNA polymerase fits into the transcription initiation complex like a key into a lock. This ‘unlocks’ the DNA, preparing it for copying. Ribosomes are organelles that construct the proteins that the cell needs to survive and repair itself. Ribosomes can’t start working without being told what to build. They need instructions in the form of mRNA. RIbosomes will build whatever protein the mRNA tells them to. Scannable Object Transcription Initiation Complex Definition A transcription initiation complex is a molecule attached to a strand of DNA. The transcription initiation complex works as a team with RNA polymerase to prepare a DNA strand for copying. A vacuole is a large sack of water, proteins and enzymes. The aquaporins on its surface are used to control its intake of water. Vacuole Vesicles are protective bubbles used to store and move molecules. Vesicle Virus Virus DNA mRNA A virus is a small particle that can only make more of itself by infecting a cell. A virus tries to inject its DNA into a cell’s nucleus. If it’s successful, a virus can replace the cell’s DNA with its own. This turns the cell into a zombie whose only function is to make more viruses. The cell needs to build a strong virus defense force of lysosomes to survive. Every cell has DNA, but viruses have their own version of DNA called virus DNA. When a virus infects a cell, it tries to sneak its virus DNA into the cell’s nucleus. Once it’s inside the nucleus, the virus DNA can hijack the cell’s DNA and take over the cell. This forces the cell to make more viruses. mRNA is a copy of a DNA strand. The ‘m’ in mRNA stands for ‘messenger.’ mRNA delivers instructions to other parts of the cell. Ribosomes can use mRNA to make proteins, which can be used to repair damaged cell parts.
