Chapter 3 Test Review 1. State the function of each of the following parts: • Cell Membrane – allows material to enter and leave the cell • Mitochondria – take food and releases energy for the cell • Cytoplasm – jelly-like substance in the cell membrane • Nucleus – directs all cell activity 1. State the function of each of the following. • Cell wall – protects the plant cell and gives it shape • Golgi Bodies- flattened materials that package cellular substances and sent them out • Organelles – structures within the cytoplasm of eukaryotic cells • Lysosomes – contain digestive chemicals to breakdown waste • Vacuoles – membrane bound space for temporary storage in cells 2. State the Cell Theory • All cells come from other cells that already exist. 3. What are the differences in an animal and plant cell? • Plant Cell – Has a cell wall – Has chloroplast • Animal Cell – Do not have cell walls – Do not have chloroplast. 4. Know the organization of all living things (start with the cell). • • • • • Cell Tissue Organ Organ System Organism • Cell is the smallest unit of an organism. 5. What is tissue? • A group of cells that work together to do one job. 6. What is an organ system? • A group of organs working together to perform a certain job. 7. What is the definition of a prokaryotic cell? Give an example. • Cells found only in one – celled organisms. • Bacteria 8. The ______ is usually the largest organelle in the cell. • Nucleus 9. Explain the difference between eukaryotic and prokaryotic cell. • Eukaryotic Cells – Found in many celled organisms that contain organelles. – Have a membrane bound structure. • Prokaryotic Cells – A one celled organism that does not contain organelles. Found in bacteria. – Do not have a membrane bound structure. 10. What is one difference between one celled organisms and cells that make up an organ? • Single celled – perform all their life functions by themselves. • Organ cells – work together and depend in some way on other cells. Be able to label a plant and animal cell. Look at worksheet # 27 Test Tomorrow Be Sure To STUDY!!!!! It’s your choice!
