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?
