Cytoplasm a. _________________________________________________________________________________________________________ b. _________________________________________________________________________________________________________ c. _________________________________________________________________________________________________________ Directions: Match the vocabulary word with the correct definition by placing the letter of the definition next to the word. _____ Nucleus _____ Chromosome _____ Cytoplasm _____ Nuclear membrane _____ Ribosome _____ Cell Wall _____ Mitochondria _____ Chloroplast _____ Endoplasmic Reticulum _____ Golgi apparatus _____ Cell Membrane _____ Vacuole _____ Lysosome _____ Nucleolus A. Supports a plant cell. B. The brain of the cell. C. Where photosynthesis takes place. D. Tubular passageways that move the protein throughout the cell. E. A structure in a cell that receives proteins and other newly formed materials from the ER, modifies them, packages them, and distributes them to other parts of the cell. Often known to store energy in the cell. F. The outer covering of an animal cell. G. Destroys the bad or injured parts of a cell and breaks down large food molecules. H. A rod-shaped cell structure that converts chemical energy in food to energy the cell can use to carry out its functions. Often referred to as the powerhouse of the cell. I. The boundary around the nucleus that keeps the DNA inside and organelles outside the nucleus. J. Makes ribosomes. K. A small grain-like structure in the cytoplasm of a cell where proteins are made. L. Holds the DNA or blue prints. M. A sac inside a cell that acts as a storage area. N. Many of the organelles float around in this. Directions: Complete each sentence with the appropriate vocabulary word. 1. If the _______________________________________ in a cell were to stop functioning then the cell would die because it would have no proteins. 2. The _____________________________________________ is like FedEx because it packages materials, and ships them throughout the cell. 3. The function of _____________________________________ can be compared to that of the stomach because it digests large food particles into smaller parts. 4. The ______________________________________________ is a very important structure in the cell because it is responsible for keeping the DNA inside the nucleus. 5. Animal cells are unable to make their own food because they do not have _______________________________________ like plant cells do. 6. ___________________________________________ are known as the power houses of the cell because they give the cell energy necessary to function.
