Photosynthesis & Respiration L.O. Students will be able to describe the process of photosynthesis and cellular respiration.

What is Photosynthesis What is Photosynthesis? photo: light synthesis: putting together The process of photosynthesis is a chemical reaction. It is the most important chemical reaction on our planet.

Describe Photosynthesis

What is the equation for the chemical reaction of photosynthesis? Six molecules of carbon dioxide react with six molecules of water to form 1 molecule of glucose and six molecules of oxygen.

Describe Photosynthesis process changing light energy to chemical energy. Need: light energy, CO2, and H2O Energy stored as sugar, Oxygen is released Occurs in plants and some algae Takes place in the chloroplasts, using chlorophyll, the green pigment in plants

What happens during photosynthesis? Carbon dioxide enters the leaf through holes called stomata. Stoma Mesophyll Cell Chloroplast

Chloroplast Organelle where photosynthesis takes place. Stroma Outer Membrane Thylakoid Granum Inner Membrane

What happens during photosynthesis? Draw this in your notebook

Why is photosynthesis important to us?

Why is photosynthesis important to us? Plants are the first step in the food chain. We cannot make our own food (glucose) We must get our food from plants oxygen released during photosynthesis is necessary for all living things.

What is Cellular Respiration? The release of chemical energy for use by cells.

What is Cellular Respiration? Once the energy that was in sunlight is changed into chemical energy by photosynthesis, an organism has to transform the chemical energy into a form that can be used. This process is cellular respiration.

Describe Cellular Respiration The breakdown of glucose molecules to release energy Takes place in all living things step by step process

What is the chemical equation for cellular respiration?

What is the chemical equation for cellular respiration?

How are photosynthesis and cellular respiration related? The equations.... What one produces the other releases.

Photosynthesis 6O₂ + CH₁₂O₆ 6CO₂ + 6H₂O Respiration
