  1. Cellular Respiration Equation
    Image Upload 1
  2. Mitochondrion
    Structure in a cell where cellular respiration takes place
  3. Cellular Respiration
    The "burning" of food to RELEASE energy for the cell to use
  4. Photosynthesis
    • Producers (plants) make their food.
    • Image Upload 2
  5. Glucose
    sugar use as a fuel for cells
  6. DNA
    Program of Life
  7. Chromosome
    A structure that houses DNA (genes)

    • (46 in a human non-sex cell)
    • (23 in a human sex-cell)
  8. Gene
    A section of DNA that is a chemical code for something a cell needs
  9. Sperm
    Male sex cell
  10. Egg
    Female sex cell
  11. Asexual Reproduction
    Reproduction that does NOT involve two parents
  12. Budding
    Asexual reproduction- parent does NOT split into two equal parts
  13. Fertilization
    Sperm joins an egg cell
  14. Cell Division
    • one cell becomes two
    • Parent cell doubles its chromosome number temporarily and then the two daughter cells get same number of chromosomes as the parent cell
  15. Life Cycle
    The stages of development of an organism
  16. Metamorphosis
    A life cycle in which young do not look like their parents
  17. Producer
    Organism that make their food.
  18. Consumer
    Organism that has to get their food.
  19. Herbivore
    Plant Eater
  20. Carnivore
    Meat Eater.
  21. Omnivore
    eats plants and meat.
  22. Predator
  23. Prey
  24. Scavenger
    eats what it did not kill
  25. Decomposer
    Bacteria and Fungi. Breaks down the remains of dead organisms.
  26. Consumer Order
    Feeding place in food chain.
  27. Food Chain
    Who eats whom
  28. Food Web
    Diagram that shows all possible food chains in a given area
  29. Energy Pyramid
    Diagram that shows the amount of energy and numbers of organisms at each feeding level
  30. Biomagnification
    The movement and accumulation of a toxin (poison) in a food chain.
  31. Top Predator
    Highest consumer order in a food chain
  32. Energy
    • Cannot be created (made) or destroyed- just transformed (changed from one form to another)
    • Example: Sunlight energy changed to chemical (food) energy
    • Example: Food energy changed to heat energy.
    • Energy CANNOT be recycled. Only matter can be recycled
  33. Dichotomous Key
    A method to identify an organism by choosing between two statements
  34. Fraternal Twins
    Results from two seperate egg cells and sperm cells
  35. Identical Twins
    One egg is fertilized by one sperm but then splits into two cell masses
  36. Nuclear Envelope
    Surrounds and protects nucleus
  37. Spindle Fibers
    Structure that seperate chromosomes during cell division
  38. Cancer
    Abnormal cell division. Cells dividing out of control
  39. Chloroplast
    Contains chlorophyll to make food in plant cell
