Water enters the plant through the
roots and travels up to the leaf through
the veins.
Water then travels to each cell through a process known as OSMOSIS.

Stomata
Stomata are the little “holes” on a plant leaf that regulates the gas exchange in plants.

Carbon dioxide then travels to each cell through a process known as Diffusion.
Carbon dioxide enters the leaf
through the stomata.

Light and Pigments
Photosynthesis depends on pigments -proteins that absorb some light and reflect others.Examples: chlorophyll and
carotene

Light and Pigments
Chlorophyll absorbs blue, violet, and red light, but reflects green light. This is why plants are green.
Carotene reflects orange light.

The 2 Steps to Photosynthesis
1. Light-dependent reactions
2. Calvin Cycle (AKA: Light-independent reactions)

Step 1:Light-Dependent Reactions *requires light*
PurposePurpose: To make oxygen used by other organisms
Location:Location: Thylakoid membranes

Step 1: LDR
How it works:How it works:
H2O is broken up by light into H+ and O2.
O2 is released through stomata

Step 2: The Calvin Cycle (Light-Independent Reactions)
* does not need light*
Purpose:Purpose: To make glucose from CO2

Calvin CycleHow it works:How it works:
6 CO2 enter the cycle and are converted into glucose.
With TWO turns of Calvin Cycle, you make ONE glucose.
