How Plants WorkHow Plants Work

Quick intro to photosynthesis!Quick intro to photosynthesis!

Plants are the basis of all lifePlants are the basis of all life

able to turn materials most organisms cannot use into something they need

through a process called photosynthesis, plants can convert carbon dioxide (CO2) and water (H2O) with the help of the sun and turn it into sugar (C6H12O6) and oxygen gas (O2)

PRETTY AMAZING!

How is it done?How is it done?

plants use leaves to capture energy from sunlight

like solar panels on your roof to make hot water

inside the leaf there are beads of green organs called chloroplasts

the chloroplasts are able to capture the sun’s energy and uses it to fuel the “magical” stage of photosynthesis

Making FoodMaking Food

after collecting energy from the sun, the plant can now start making sugars

this process of making sugar from water and carbon dioxide was discovered by an American biochemist named Melvin Calvin

Making FoodMaking Food

he found that there was a cycle happening in the plant where it took the energy from the sun to start a cycle of reactions that resulted with sugar

he realized this is the food the plant uses to stay alive

his discovery was later named the Calvin Cycle

Steps of Photosynthesis

Uses sugar for food or reinforcement (bark, stems, leaves)

At night there’s no sun!At night there’s no sun!

at night when the sun is gone, the plant is still needing energy

so now the plant needs to metabolize something (break a molecule) for energy

the plant stores the sugar it made during the day to use later at night when it needs a snack!

Photosynthetic EquationPhotosynthetic Equation

6 CO2 + 6 H2O C6H12O6 + 6 O2

Problem – this doesn’t show the magic of photosynthesis. It gives the ingredients but doesn’t explain how it’s done.
