Photosynthesis

What is Photosynthesis? A process that converts light (solar) energy into stored (chemical) energy in the form of food molecules like glucose or starch AUTOTROPHS Process used by AUTOTROPHS like plants and algae to make food.

Where does photosynthesis take place? Inside the leaves Inside the cell Inside the chloroplast

What does photosynthesis require? The process requires: Sunlight Sunlight – source of energy Chlorophyll Chlorophyll, the green pigment that captures light energy. Water (H 2 O) Water (H 2 O) Carbon dioxide (CO 2 ) Carbon dioxide (CO 2 )

6H 2 O + 6CO 2 C 6 H 12 O 6 + 6O 2 WATER + CARBON  GLUCOSE + OXYGEN DIOXIDE The photosynthesis equation

Where does photosynthesis take place? Inside the chloroplast – Chlorophyll is found inside the chloroplast

Stages of Photosynthesis 1.Energy is captured from sunlight. 2.Light energy is converted to chemical energy stored. 3.The stored energy transforms into carbohydrates using CO 2

Summary of Photosynthesis sunlight 6CO 2 + 6H 2 O + sunlight  C 6 H 12 O 6 + 6O 2 What are the reactants (needed) for photosynthesis? What are the products (made) of photosynthesis?

Types of Organisms Autotrophs Make their own food Heterotrophs Obtain energy from the food they consume or absorb

ENERGY Energy is the ability to do work
