Bio 150 - Module 2.2 Photosynthesis

Photosynthesis is made up of (Carbon Dioxide, Water, and Light)

This process releases oxygen

almost all organisms receive Energy from the sun

To conduct photosynthesis, you need an organelle called chloroplasts

Structure of a leaf:

The outermost layer of a leaf is the Cuticle. (Protects while also retaining water)

Epidermal cells contain Storma to allow gas exchange

Mesophyll is the middle of the leaf where photosynthesis happens

Chloroplast Structure:

Pigments capture sunlight

Chlorophyl A makes plants green

2 stages of photosynthesis:

Light Dependent Stage - light being captured by pigments in Thylacaid

Light Independent Stage - Happens in Storma (Carbon Fixation)

The Calvin Cycle = (Bring in C02 —→ Use the Energy —→ Make Glucose)

We rely on photosynthesis because it produces oxygen for us
