Name _______________________________________________ Date ____________________ Period _____ Levels of Organization Microscope Lab Follow-up Questions Correct Information from the Lab: Organ systems we looked at Functions of those organ systems Organs we looked at in these systems Reproductive system Produces male and female sex cells Flower, Testes Respiratory system Permits the exchange of gases in the body Lung Circulatory system Lymphatic system Digestive system Nervous system Transports oxygen, wastes, and digested food throughout the body Returns extra fluid to the circulatory system and filters out harmful materials like bacteria Receives, transports, breaks down, and absorbs food throughout the body Conducts messages throughout the body to aid in coordination of body functions Heart Lymph node Stomach Cerebrum Integumentary system Protects the body Fat Endocrine system Regulates various body functions Thyroid gland Muscular system Supports the body and enables it to move Skeletal muscle Skeletal system Protects and supports the body Bone Excretory system Removes liquid and solid wastes from the body Kidney Shoot system Root system Provides support for plant, exchanges gases, produces sugar, and transports materials around the plant Anchors the plant to the ground, stores nutrients, and absorbs water & minerals from the soil Leaf, stem Root Questions: 1. List the six levels of organization in order from simplest (a) to most complex (f). a. _________________________________________ b. _________________________________________ c. _________________________________________ d. _________________________________________ e. _________________________________________ f. _________________________________________ __________________ __________________ 2. In animals, the respiratory system is responsible for exchanging gases with the environment. What organ system of a plant has the same function? 3. In plants, the shoot system is responsible for transporting materials between different organs in the body. What organ system in an animal has the same function? __________________ 4. The digestive system breaks food into simpler substances for cells to use. One of these simpler substances is called an amino acid. Amino acids are hooked together to make proteins. What organelle would you expect to find a lot of in a cell that was doing this? __________________ 5. The nervous system senses changes in the environment and allows the organism to adapt. What organelle does this for bacteria and archaea cells? __________________ 6. The circulatory system transports materials around the body through a series of tubes (veins and arteries). Name 2 organelles, shaped like tubes, that transport materials around a cell. __________________ 7. The lymphatic system helps destroy harmful bacteria. What organelle would it need to do this job? __________________ 8. The integumentary system is mostly made up of your skin. This forms a flexible barrier between the inside and outside of your body. What organelle does this same job for the cell? __________________ 9. Glands within the endocrine system control body processes by making and releasing hormones. In order for these hormones to do their job they need to be packaged and shipped to other parts of the body. What organelle would it need to do this job? __________________ 10. The muscular system helps animals move. Name 2 organelles that help cells move. __________________ 11. In order to do its job of helping an animal move, the muscle cells require a lot of energy (ATP). What organelle would it need a lot of to provide this energy? __________________ 12. The shoot system of a plant provides support for the body and gives the plant its overall shape. What organelle does this for the cells of a plant? __________________ 13. The leaves of a plant are responsible for making the sugar that feeds the rest of the plant. What organelle would it need to do this job? __________________ 14. The root system of a plant absorbs and stores water for the plant to use later. What organelle would it need to do this job? __________________ 15. We looked at many different body parts of mammals like pigs, cows, humans, and monkeys. What is the name given to the period of development that these organisms go through inside their mother’s placenta? __________________ 16. We looked at a few different parts of plants, like flowers, stems, cones, and leaves. What is the name given to the period of development that these organisms go through inside a seed? __________________ 17. What is the name given to the event that starts the periods of development talked about in questions 15 and 16? 18. We focused mainly on the organs and organ systems of plants and animals in this lab. Why didn’t we look at any bacteria or archaea organs or organ systems? ______________________________________________________________________________________ ______________________________________________________________________________________ 19. The skeletal system and the cell wall have very similar functions. Explain why you would not find cell walls in the bone cells of the skeletal system. ______________________________________________________________________________________ ______________________________________________________________________________________ 20. Were the cells you looked at in this lab stem cells or specialized cells? How can you tell? ______________________________________________________________________________________ ______________________________________________________________________________________
