  1. STAAR Review Cells & Human Body

  2. 2013 STAAR Testing Strategy The Couch’s spadefoot lives in Texas and has the characteristics listed below. • Their pupils are vertical slits. • Adults have mottled brown back and light-colored bellies. • Their eggs and tadpoles develop quickly in the temporary ponds forming after rain. • Adults live in holes they dig using special “spades” on their rear feet. • Adults eat insects and spiders. The Couch’s spadefoot is adapted to a certain type of environment. Which of these resources is most likely scarce in this environment? A. Soil B. Sunlight C. Water D. Oxygen

  3. Cells Prokaryote vs Eukaryote

  4. Draw in journal and fill in using above words. Prokaryote Eukaryote

  5. Prokaryote Cells on head of a straight pin. Single-celled Small Reproduce quickly Ex. Bacteria

  6. Prokaryote Cell Structure Cell Wall Cell membrane Nucleoid Cytoplasm Ribosomes Flagella

  7. Using white boards list some items you recall about the prokaryotic cell

  8. Prokaryote Cells Some items you may have listed nucleoid cell wall cytoplasm ribosomes flagella E Coli streptococcus Small Single celled Bacteria Reproduce quickly Salmonella

  9. Eukaryote Cells Large Nerve Multi-celled Tissue More complicated Blood Ex. Plant, Animal, Fungi

  10. Eukaryote Cell Structure

  11. Using white boards list some items you recall about the eukaryotic cell

  12. Eukaryote Cells Some items you may have listed Bone nucleus cell wall cytoplasm ribosomes chloroplast Muscle Large Multi-celled Plant, Animal, Fungi Complex Cartlidge

  13. Now what do you recall. Update your first drawing in journal Prokaryote Eukaryote

  14. 2013 STAAR Testing Strategy Scientists studying aquatic plants notice flooding often leads to a decrease in their rate of photosynthesis. Flooding causes more sediment to be suspended in the water thereby decreasing the amount of light reaching the plants. Why does a decreased rate of photosynthesis lead to a decrease in a plant population? Less water is available for absorption. Less tissue is available for plant growth. Less energy is available for reproduction. Less soil is available for leaf development.

  15. 2013 STAAR Testing Strategy The characteristics of a particular organism are listed below. • Is multicellular • Is autotrophic • Has cell walls • Has cell nuclei • Can reproduce sexually or asexually In which kingdom should this organism be classified? Fungi B. Eubacteria C. Plantae D. Animalia

  16. Human Body Systems

  17. Take the cards provided and match them using the following order Row 1 = system name (alphabetized Row 2 = system picture Row 3 = key organs in system Row 4 = function of system When finished check against the next few slides. Then copy four systems in your journal to include picture.
