Name Grade Four Science The World of Living Things Fourth Quarter Plant Parts Match the parts of the plant in the picture with the description of its function. Use the letter as often as needed. 1. 2. 3. 4. 5. 6. 7. 8. 9. Provides the plant with water. Holds plant up so leaves can get sunlight. Contains chlorophyll Absorbs carbon dioxide Holds plant in ground Provides the plant with minerals and other nutrients Where food for the plant is made Moves food, water, and nutrients to the other parts of the plant. Gives off oxygen Name the parts of the flower shown in the picture using the letter. Then write the same parts next to their main function in reproduction. A. pistil B. anther C. egg D. petal E. ovary Part: 10. 11. 12. 13. 14. Function: 15. 16. 17. 18. 19. produces the pollen containing male sex cell contains the egg cells and forms fruit attracts insects with its color place where pollination occurs the female sex cell 10/24/08 Plant Facts Write the letter of the best answer in the blank. 20. Some scientists classify plants by a. the way they grow. b. the way they reproduce. c. their color. d. all of the above. 21. A fern plant has no a. roots b. 22. . leaves The moss plant grows from a a. seed b. spore . c. flowers d. stems c. . flower d. moose 23. Many plants depend on insects or animals for carrying their pollen and for . a. scattering their seeds b. holding them up c. picking their flowers d. eating them 24. The only organisms that can make their own food are a. people b. animals c. green plants d. insects 25. The part of a plant that you are eating when you eat a vegetable could be the . a. leaf b. stem c. fruit d. all of the above 26. The holds a plant in the soil and takes in water and other materials to make food. a. root b. stem c. leaf d. flower . 10/24/08 Plant Interactions 27. Study the three pictures. What do they have in common? Tell something about each picture. Classifying Plants Look at the pictures of the plants below. Use the letter of the plant to answer the questions that follow. 28. Which plant makes seeds but has no flowers? 29. Which plant has no flowers and no seeds? 30. If we sometimes classify plants by the way they reproduce, which plant belongs with a rose? 10/24/08 31. Characteristics of plant leaves are often used to group trees by their similarities and to identify them by name. We often use a dichotomous key. Use this portion of a dichotomous key to describe the White Ash Tree. Study the pictures and check the appropriate box for each part. √ 10/24/08 Fossils 32. The diagram shows different rock layers. Different kinds of fossils are contained in each layer. Study this diagram. What could you tell about Layer B if you found both plant fossils and animal fossils in the same layer? 10/24/08 Photosynthesis Match the letter from the diagram to the function listed below. One letter will be used more than others. 33. 34. 35. 36. 37. 38. 39. The sun provides the plant with energy. Water and minerals are taken from the soil. Water and carbon dioxide are combined here to make sugar. Oxygen and water vapor are given off. Carbon dioxide enters through openings called stomata. Water and food move up and down to all parts of the plant. is the green substance in plant cells that helps plants make food by trapping the Sun’s energy. a. b. Oxygen Chlorophyll c. d. Carbon dioxide Epidermis Plant Life Cycles Write the letter for each event in the order they occur in the life cycle of a flowering plant. a. germination b. plant grows to maturity c. fertilization d. death pollination 40. seeds grow in ovary 41. 42. 43. 10/24/08
