Energy Autotrophs

Use energy from sun to make their own food

Heterotrophs Cannot make their own

food, so they eat autotrophs or other heterotrophs for food.

What is photosynthesis?

Plants take energy from the sun and store it as sugars

Equation for Photosynthesis

+ light energy

Light & Pigments Visible Spectrum

White light can be broken down into colors

Pigments Absorb certain colors of

light Reflect colors not

absorbed

Chloroplast Pigments Chlorophyll

Located in the THYLAKOID

Absorbs red and blue light and reflects green

Carotenoids

Accessory pigment for colors yellow, orange, & brown

Parts of Photosynthesis Light Reactions

Require light Occur in the THYLAKOIDTHYLAKOID

Dark Reactions Does not require light Occurs in the STROMASTROMA

Light Reactions

SunlightSunlight and WaterWater are used to make ATPATP and NADPHNADPH Sun excites electrons and

they go to a higher energy level

OXYGEN (OOXYGEN (O22)) is released

This provides fuel for the dark reactions

Dark Reactions…the Calvin Cycle Uses COCO22, ATPATP, and

NADPHNADPH to make PGALPGAL

PGAL is a building block to make glucose Carbohydrate sugar

Autotrophs & Heterotrophs An organism that makes its own food is called an autotroph. An organism that cannot make its own food is called a heterotroph.

Cell Respiration. Consumers/ Heterotrophs Autotrophs use sunlight to make ATP and Glucose Heterotrophs – get glucose from eating other organisms and using.
