CH 7 – Plants Draw, label and color the picture of Photosynthesis on p. 217 Energy Processing in Plants Put a check mark in the appropriate space to show which process is being explained. Process Photosynthesis Cellular Respiration 1. 2. 3. 4. 5. 6. 7. 8. Carbon dioxide is one of the reactants Energy in the form of ATP is released Glucose is a product This occurs within chloroplasts This process requires light energy One of the products is water Sunlight is needed for this process This process takes place in mitochondria 9. The result is a usable form of energy called ATP 10. Oxygen must be present as a reactant 11. Life depends on this process 12. This occurs in plants 13. Oxygen is released from the plant 14. These processes are interrelated 15. Water molecules are split apart 16. Atoms combine to form sugar 17. This is required for growth and tissue repair 18. It produces 90 percent of oxygen in the atmosphere 19. How are photosynthesis and cellular respiration interrelated? ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ LESSON 2 – PLANT RESPONSES - Highlight the best choice. 1. Light, touch, or gravity that causes plant growth toward or away from a stimulus is a (chemical hormone, tropism). 2. A plant’s tropism to light is called (phototropism, gravitropism). 3. Bending toward the light is a (positive, negative) tropism. 4. If a planter is turned so the plant bends away from the light, the plant will gradually (bend lower, straighten). 5. The plant’s stems (will, will not) continue to grow upward if the plant is placed in the dark. 6. Roots that grow (toward, away from) the Sun help anchor the plant in the soil. 7. Some plants respond to touch. This is called (thigmotropism, photoperiodism). 8. A higher level of a plant hormone called (gibberellins, auxin) on the dark side of the plant causes plant cells found there to grow longer. 9. When plant cells on the dark side of a plant grow longer, the plant (bends, dies).
