Photosynthesis
I. Photosynthesis in Overview
A. Process by which plants and other
autotrophs turn the energy of sunlight
into sugars. Requires sunlight, water,
and carbon dioxide.
B. Overall equation:
6 CO2 + 6 H2O + Light  C6H12O6 +
C. Occurs in the leaves of plants in
organelles called chloroplasts.
6 O2
II. Plant Leaf Structure
A. Basic Leaf Structure
1. Stomata (Stoma)
2. Mesophyll Cell
3. Chloroplasts

II. Plant Leaf Structure
B. Basic Leaf Structure
1. Stomata (Stoma) are pores in a plant
leaf surface through which water and
gases are exchanged between the
plant and the atmosphere.
Oxygen
(O2)
Carbon Dioxide
(CO2)
II. Plant Leaf Structure
A. Basic Leaf Structure
2. The mesophyll cell is a cell found on
the surface of a leaf.
Nucleus
Cell Wall
Central Vacuole
Chloroplast

3. Chloroplasts are tiny organelles within
the plant cell where photosynthesis
takes place.

Plants take in carbon dioxide (CO2)
Plants take in water (H2O)
Plants absorb light (Light)
Sugar (plant food) is created (C6H12O6)
Oxygen is produced and released (O2)
6 CO2 + 6 H2O + Light  C6H12O6 + 6 O2
