PHOTSYNTHESIS, PLANT GROWTH AND
REPRODUCTION REVIEW
PHOTOSYNTHESIS

 Whatare the two
 materials a plant
 must take in to
 conduct
 photosynthesis?
PHOTOSYNTHESIS

 What are the two
 materials a plant
 produces as a
 result of
 photosynthesis?
PHOTOSYNTHESIS

 Consumers  get
 their energy from
 the food they
 eat, but
 producers get
 their energy from
 the ___________
PHOTOSYNTHESIS

 What pigment
 gives plants their
 color and
 captures
 sunlight for
 photosynthesis?
PHOTOSYNTHESIS
 Lishon  tested
  this leaf for
  starch. He found
  there was no
  starch in the
  white spots.
 Explain why.
PHOTOSYNTHESIS
 Jaha helped test
 for starch. What
 element did she
 put on the leaf
 and what color
 would it turn if
 starch were
 present?
PHOTOSYNTHESIS
 Dazhanae    wanted
  to get in on the
  science fun too…
 She wanted to test
  the rate of             Should she measure:
  photosynthesis at           Bubbles of Carbon dioxide
                               produced
  different                   Bubbles of Oxygen
  temperatures.                produced
                              Amount of sunlight that hits

 Max  helped
  Dazhanae graph the
  results.
 They had data for
  temperature and  Independent Variable:
  bubbles of gas       Bubbles of gas produced

                       Temperature
  produced. Which was
  the INDEPENDENT
  VARIABLE?
                    The map below shows the
RANDOM SCIENCE       concentration of chlorophyll
                     in the surface of the ocean.
                     In which hemisphere is the
                     most photosynthesis taking
                     place?

LEAF STRUCTURE

                  What  is the
                  function (job) of
                  stomata (holes)
                  on the underside
                  of a leaf?
HEALTHY PLANT GROWTH

 What are the three main minerals needed
 for healthy plant growth?
    LEAF STRUCTURE

 what is pollination?
LIFE CYCLE
Point  to the site
 of pollination.
What is this
 structure?
Is it male or
 female?
LIFE CYCLE
Point  to the site
 of fertilization.

 being pollinated? Explain.
 LIFE CYCLE


Josh  loves apples...
What must happen
 for fruit to grow?

 flower develops
 into a fruit?
    RANDOM SCIENCE

   The rafflesia flower is the
    largest flower in the world!


                                    Growing up to
                                    100 cm wide,
                                    this flower grows
                                    on a vine and
                                    smells like rotten
