PHOTOSYNTHESIS
What are 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
Should she measure: Bubbles of Carbon
dioxide produced Bubbles of Oxygen
produced Amount of sunlight
that hits the plant
Dazhanae wanted to get in on the science fun too…
She wanted to test the rate of photosynthesis at different temperatures.

PHOTOSYNTHESIS
Independent Variable: Bubbles of gas
produced Temperature
Max helped Dazhanae graph the results.
They had data for temperature and bubbles of gas produced. Which was the INDEPENDENT VARIABLE?
RANDOM SCIENCE
Photosynthesis
takes place in the
ocean too!
The map below shows the concentration of chlorophyll in the surface of the ocean. In which hemisphere is the most photosynthesis taking place?
RECITE/SING/CHANT THE PHOTOSYNTHESIS POEM

TIRED YET?
Of course not! Let’s keep learning!
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 Donte dissected this leaf. Help him
find the palisade layer? Spongy layer? Waxy cuticle?
LIFE CYCLE OF PLANTS
What is it called when a seed first begins to grow?
LIFE CYCLE In one sentence,
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.
What is this structure?
Is it male or female?
LIFE CYCLE Can a flower be fertilized
without being pollinated? Explain.
LIFE CYCLE
Josh loves apples... What must happen for fruit to grow?
What part of the 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 meat!
Reproductive structures of a rafflesia.
Picture taken from inside a rafflesia flower
LIFE CYCLE

What job do they help flowers do?
LIFE CYCLE
Najee researched some wind pollinated plants…
What are their anthers like that helps them distribute pollen without insects?
