Light as a Factor in Photosynthesis GERANIUM LEAF LAB

Sketch the Geranium leaf. Color matters!

Sketch the leaf with part being covered to prevent exposure to light

Sketch the Geranium leaf after treatment (boiling) in warm alcohol

Sketch the Geranium leaf after treatment with Lugols

Questions to consider: What effect did the paper have on the leaf? Why did this happen? Write a brief conclusion for this lab.

Pigment as a Factor in Photsynthesis Coleus Leaf Lab

Sketch the Original variegated Coleus leaf shown Color matters!

Sketch the Coleus leaf after treatment (boiled) with alcohol

Sketch the Coleus leaf after treatment with Lugols

QUESTIONS TO CONSIDER: What did the Lugol’s indicate about the leaf? Where is this substance found in the leaf? Write a brief conclusion for this experiment.

Gas as a factor in Photsynthesis Elodea Lab

Sketch the bottle with Elodea and BTB, remember color matters! DAY 1 in Light Sketch the bottle with Elodea and BTB, remember color matters!

Sketch the bottle with Elodea and BTB, remember color matters! DAY 2 after 24 hours Sketch the bottle with Elodea and BTB, remember color matters!

Questions to consider: What changes did you observe in the bottle? Why did these changes occur? What does this indicate? Write a brief conclusion for this experiment.

Photosynthesis Process of converting suns energy into chemical energy (food) ATP is the ‘fuel’ for the plant Usable energy Plants need Sunlight ( leaves are like solar panels) Water (roots take in water) Chlorophyll (green parts) CO2 ( enters through small porous openings under the leafs)

Photosynthesis Plants take in the previous four substances Sugar is produced Used for food Release O2 WHAT WE BREATHE! General Equation: 6CO2 + 6H20 C6H12O6 + 6O2
