Photosynthesis

Photosynthesis

​The terms for Photosynthesis

Photo=Light and synthesis=make so the two of them together make photosynthesis and it is known as the process of making food.

What does Photosynthesis do

Photosynthesis is the process of converting light energy into stored chemical energy in the form of glucose.

Multiple Choice

What energy does photosynthesis convert and how?

• Heat Energy to Chemical Energy in the form of Lactose

• Light Energy to Stored Mechanical Energy in the form of Glucose

• Light Energy to Stored Chemical Energy in the form of Glucose

• Chemical Energy to Light Energy in the form of Dextrose

​Why are plants green?

Plants are green because of a special organelle called Chlorophyll

What does Chlorophyll do?

What chlorophyll absorbs the light which is used to make plants green.

Plants reflect light

Plants reflect green light and absorb the rest of the colors

Multiple Choice

What makes plants green

• Chlorophyll
• Sunlight
• Water
• Soil

​Where it all takes place

Photosynthesis all takes place in an organelle called chloroplast

What all Photosynthesis requires

Photosynthesis requires Light, Carbon Dioxide, Oxygen, and Water.

The formula for photosynthesis

6CO2 + 6H2O -> C6H12O6 +6O2

Multiple Choice

What are the elements in Photosynthesis

• Carbon Dioxide, Water, and Light
• Oxygen, Nitrogen, and Hydrogen
• Carbon, Hydrogen, and Oxygen
• Nitrogen, Oxygen, and Carbon Dioxide

​What is needed in the formula

1. Carbon Dioxide 2. Water and 3. Light

​What is received from the formula

Glucose and Oxygen are recived.

The reactants and products of photosynthesis

The reactants are Carbon Dioxide, Water, and light. The products are Glucose and Oxygen.

Multiple Choice

What are the reactants in the photosynthesis formula

• Carbon dioxide Light and Water

• Oxygen and glucose
• Nitrogen and hydrogen
• Sodium and chlorine

Multiple Choice

What are the products in the photosynthesis formula

• Oxygen and Glucose
• Carbon Dioxide and Water
• Sunlight and Chlorophyll
• Nitrogen and Potassium

​Recaping

Photosynthesis happens in the Chloroplast and needs Carbon Dioxide, Water, and Light Energy.

​Recaping cont.

Photosynthesis converts Light energy into stored chemical energy. Chlorophyll makes plants green by absorbing light of all the colors and reflecting green light.

Recap End

The formula for photosynthesis is
6CO2+6H2O -> C6H12O6+6O2
Carbon Water Light Glucose Oxygen
Dioxide
