Mitochondria I am the powerhouse of the cell. I am responsible for generating the cell’s energy. Cell Membrane I keep the cell together and give it its shape. Some substances, such as water and oxygen, can pass through me but other substances cannot. I control what enters and leaves the cell. Cytoplasm I am the jelly-like substance inside the cell. I contain many important substances that are needed for chemical reactions. Smooth ER You can find me in many different cells types and my role in each differs. I make lipids, phospholipids and steroids. Compared to my rough friends, I’m smooth because ribosomes don’t like me. Nucleus I am the control centre of the cell. I contain DNA in the form of chromosomes and control what the cell does and when. Ribosomes I am the protein builder. My job is extremely important, as proteins are needed for many functions within the cell and the whole organism. As a construction guy I connect one amino acid at a time to build long protein chains. Centriole my main function is to help with cell division in animal cells. I help the formation of the spindle fibers that separate the chromosomes during cell division Rough ER I am a network of structures responsible for the synthesis of proteins. They call me rough because I’m surrounded by ribosomes. Golgi Apparatus I am a packaging centre within the cell. I combine simple molecules to make complex molecules for packaging in vesicles. Sometimes these vesicles are transported out of the cell. I also look like a stack of pancakes! Lysosome I am the waste disposal system of the cell. I am responsible for the digestion and removal of macromolecules the cell no longer needs. I also breakdown the bacteria that enters the cell. I am the destroyer! Chloroplasts I am oval in shape and am home to a green substance called chlorophyll. I help trap sunlight to make food for my boss. While I am exclusive to plants, you will not find me in all plant cells. Vacuole I store water and dissolved substances within my walls. I am present in both animal and plant cells, however I’m much large in the latter. Cell Wall I am the tough covering around plant cells . I give them strength and hold them in shape. I am made of a substance called cellulose. Water and dissolved substances can pass through me. You will not find me in an Animal cell.
