2 Think back to the virtual plant and frog dissection you did. Using some of the parts you identified, complete the following chart. Level of Organization cell tissue organ organ system organism Animal Plant 2

3 Using the laminated cards, place the levels of organization in the correct order from smallest to most complete. Write the definition under the level. Then sort through the cards and write in the examples under the correct level. 3

4 36 The food that you eat travels from your mouth, down your esophagus, into your stomach, and through your small and large intestines before your body rids itself of solid waste. As the food passes through your body, it is digested, and you get important nutrients from the food. Which of the following is the correct term used to describe a group of body parts working together to perform a specific function? A an organism B a tissue C an organ system D an organ 37 Living things are made up of cells. Cells are organized at different levels to form very complex living organisms like your body. Each level has a specific role or job to perform. Which of the following lists these levels in the correct order of organization from the simplest to the most complex? A cells, tissues, organs, organ systems, organisms B organisms, organ systems, organs, tissues, cells C tissues, cells, organs, organisms, organ systems D organs, organ systems, organisms, cells, tissues 38 All of the following are true EXCEPT: A Skin is an organ. B Tissues are made up of organs. C Each organ is made up of its own kind of tissue. D Tissues are made up of cell. 4

5 39 All of the following are types of tissue except: A muscle B epithelial C digestive D bone marrow 41 The three major parts of the circulatory system are the heart, the blood vessels, and the blood. The heart is an organ made up of specialized cells. Which of these functions can the heart perform that individual heart cells cannot? A pumping blood B producing waste C using energy D growing larger 40 What function or process is common to all living things? A photosynthesis B respiration C movement D oxygenation 42 All of the following are characteristics of both living organisms and cells EXCEPT: A remove waste from themselves B rely on chemicals for communication C grow and die D extract energy from food 5
