  1. STAAR Reporting Category 4Organisms & environment Middle School Science Science STAAR Need to Know

  2. Journal Entry

  3. Problem: Based on the dichotomous key, how can we classify the plant?

  4. Claim:

  5. Scientific Explanation:H Leaves are arranged like a fan.

  6. PCES

  7. What are the characteristics of plant kingdom? Problem:

  8. Claim:

  9. Scientific Explanation: B Plants are autotrophic. This means that they make their own food. They are multicellular (made up of many cells).

  10. PCES

  11. A. Fungi B. Eubacteria C. Plantae D.Animalia

  12. Problem: In which kingdom does the organism belong to?

  13. Claim:

  14. Scientific Explanation: C Plant Kingdom

  15. Eukaryotic and Prokaryotic Cells Prokaryote = without a nucleus Eukaryote = with a nucleus

  16. The plasmamembrane/cell membrane the flexible boundary of a cell separates a cell from its surroundings Eukaryotic Cell Structure

  17. Eukaryotic plant cell • Plant cells are also Eukaryotic cells, but plant cells contain some organelles that are not found in animal cells.

  18. Plant Cell Organelles • Cellwall-rigid wall outside the plasma membrane. It provides the cell with extra support. • Chloroplasts-captures light and energy; and converts it into chemical energy. • Chlorophyll-green pigment found inside the chloroplast. • Plastids- organelles that store things such as food in the plant cell.

  19. PCES

  20. Problem: What is missing in the food web in order to make it complete?

  21. Claim:

  22. Scientific Explanation: Thedecomposers (bacteria, fungi) are missing from the food web.

  23. Journal Entry – Case One

  24. Scientific Explanation: D 90 % energy is lost as it moves from one trophic level to the next. 10% energy is passed on.

  25. PCES

  26. A Microscopic algae are plants and white suckers are animals. Plants = producers Animals = consumers

  27. PCES

  28. C Trees/plants are producers, and elephants/animals are consumers.

  29. Journal Entry – Case One Select the correct answer and explain.

  30. F bats owls are eaten by bats = prey owls = predator

  31. F moths bats are eaten by moths = prey bats = predator

  32. Case Two - Select the correct answer and explain
