  1. Plant Watch Unit Ms. J. Bruce 8th Grade Science Sunset Park Prep Plant Watch Unit, Ms. Bruce

  2. Your Task (Vacation or long-term assignment) • Plant a bean seed • Use soil or a paper towel • Water regularly • Place in good light source • Observe the changes that occur • Journal what happens • Shoots, leaves, height, color, etc. Plant Watch Unit, Ms. Bruce

  3. Why watch a plant grow? • Plants don’t seem to do anything! • Plants keep us alive • Plants can alter the existence of all other organisms Plant Watch Unit, Ms. Bruce

  4. We usually recognize plants by Color Structure Location Scientifically, plants are classified as any organism with the ability to Make food in their own cells i.e. use inorganic materials to make organic materials What is a plant? Plant Watch Unit, Ms. Bruce

  5. What can we see inside of plants to know that they are plants?Cell Models: An Interactive Animation Plant Watch Unit, Ms. Bruce

  6. What do we see on the outside to know that something is a plant? Plant Watch Unit, Ms. Bruce

  7. Plant Watch Unit, Ms. Bruce

  8. How do plants maintain homeostasis? Homeostasis is internal balance Plant Watch Unit, Ms. Bruce

  9. Humans maintain homeostasis using their body systems and life functions/processes like • Nutrition • Excretion • Respiration • Circulation/transport • Reproduction • Growth • Sensitivity • Structure Plant Watch Unit, Ms. Bruce

  10. The questions we want to answer are . . . • What gives a plant structure and support in the open world? • What do plants actually do to get food? • W\hat wastes do plants have and how do they get rid of it? • What gases do plants need to survive and how do they get and use them? • How does a plant move stuff around if it can’t move itself? • How do plants produce more plants? • How does a seed grow into a plant or a tree? • How do plants know what’s going on around them and how do they react? Plant Watch Unit, Ms. Bruce

  11. Humans Use this process to Have organs/structures like Plants Use this process to Have structures like For each process we will look at Plant Watch Unit, Ms. Bruce

  12. What gives a plant structure and support in the open world? Plant Watch Unit, Ms. Bruce

  13. What do plants actually do to get food?Howstuffworks "HowStuffWorks Video Channel“ Plant Watch Unit, Ms. Bruce

  14. What wastes do plants have and how do they get rid of it? Plant Watch Unit, Ms. Bruce

  15. What gases do plants need to survive and how do they get and use them? Plant Watch Unit, Ms. Bruce

  16. How does a plant move stuff around if it can’t move itself? Plant Watch Unit, Ms. Bruce

  17. How does a seed grow into a plant or a tree? Plant Watch Unit, Ms. Bruce

  18. How do plants produce more plants?Pollination video from BrainPop Plant Watch Unit, Ms. Bruce

  19. How do plants know what’s going on around them and how do they react?Plants In Motion Plant Watch Unit, Ms. Bruce

  20. Yes No What does this all mean?Are we much different from plants? Plant Watch Unit, Ms. Bruce

  21. If we could make a plant zoo, what would we put in it? • Carnivorous Plants Online - Botanical Society of America Plant Watch Unit, Ms. Bruce

  22. Homework • Make a KWL chart for this unit. • How is a plant different from an animal? • Compare a cactus to a rose to an apple tree to a pine tree. Why do you think plants have such different structures? • What proof do we have that people need plants as much as we need them? (Think about recycling!) Plant Watch Unit, Ms. Bruce

  23. Homework Cont’d In some land plants, guard cells are found only on the lower surfaces of the leaves. In some water plants, guard cells are found only on the upper surfaces of the leaves. Explain how guard cells in both land and water plants help maintain homeostasis. In your answer be sure to: • identify one function regulated by the guard cells in leaves • explain how guard cells carry out this function • give one possible evolutionary advantage of the position of the guard cells on the leaves of land plants Plant Watch Unit, Ms. Bruce

  24. A series of investigations was performed on four different plant species. The results of these investigations are recorded in the data table below. Characteristics of Four Plant Species Based on these data, which two plant species appear to be most closely related? Support your answer. Plant species ____________ and __________ What additional information could be gathered to support your answer to the previous question? State one reason why scientists might want to know if two plant species are closely related. Plant Watch Unit, Ms. Bruce

  25. Data from two different cells are shown in the graphs below. Which cell is most likely a plant cell? Support your answer. Plant Watch Unit, Ms. Bruce
