Tt holds organelles and is the place where most cell activities happen. 5. Mitochondria The power house of the cell. Tt produces energy for the cell. 6. Endoplasmic Reticulum (ER) A network of tubes. Tt helps in the transport of materials inside the cell. (Blue part - Smooth ER Pink part - Rough ER with ribosomes) T. Ribosomes Very tiny dots. They help in making proteins. 3. Nucleus The control center of the celt. It contains DNA and controls all the activities, 4. Nucleolus 8. Golgi Apparatus 9. Lysosomes A smoll round body Stack of flattened sacs Small round sacs inside the nucleus that modifies, packages that break down that helps in making ond sends proteins to waste materials and ribosomes. different parts of unwanted things in the cell, the cell. -——— =) Ye Animal cells ore usually round or irregular in shape. r | | oid They are made up of different organelles. | | 10.
