Science 1.3 - Photosynthesis & Cellular Respiration

1. What are the 2 reactants + 1 that plants take in?

Water (H20) + Carbon Dioxide (CO2) + Energy

2. What type of energy do plants need for Photosynthesis? Where is it from?

Light energy from sunlight

1. Once a plant receives all these reactants, what happens?

Plants will take light energy (sunlight) & convert water & carbon dioxide as a chemical reaction into “products”

1. What organelle does this chemical reaction happen in? How?

Organelle: Chloroplast

• Help plants take in the reactants to produce “products”

1. What products are formed from the chemical reaction?

Sugar (Glucose/C6H1206) & Oxygen (O2)

2. Eg. What are the 2 reactants in Cellular Respiration?

Sugar (Glucose/C6H12O6) + Oxygen (O2)

2. eg. How would humans get these reactants?

Sugar: One of the nutrients from food

Oxygen: Breathing oxygen

2. How does Cellular Respiration work?

It uses sugar & oxygen as reactants as chemical reaction to create “products”

2. What organelle does this chemical reaction happen in? How?

Organelle: Mitochondria

• Allows cells to produce energy

2. What are the products formed?

Energy, Water (H20), & Carbon Dioxide (CO2)

2. What does energy do? Example?

Energy fuels us in many ways (eg. movement, talking, breathing, etc.
