An example of an autotroph


NOT an example of a heterotroph

When a phosphate group is removed

Energy is released from ATP

Priestly and Ingenhousz

Scientist that showed that plants need light to grow

Carbon dioxide, water, and light

Used in the overall reactions for photosynthesis


Stack of Thylakoids

Chlorophyll doesn't absorb green light

Why plants appear green


Place in the Chloroplast that chlorophyll is found

Oxygen, ATP, NADPH

Products of light-dependent reactions

Beginning of photosynthesis

Pigments in photosystem II absorb light


Place where the Calvin Cycle takes place

Fewer Sugars will be produced

If Carbon dioxide is removed from a plant's environment

The rate of photosynthesis increases and then levels off

If you continue to increase the intensity of light that a plant receives


Organisms that make their own food


Organisms that cannot make their own food and must obtain energy from the foods they eat


NOT a part of an ATP molecule


Jan van Helmont concluded that plants gain most of their mass from this


Ingenhousz showed that plants produce bubbles when exposed to this

Oxygen and high-energy sugars

Photosynthesis uses sunlight to convert water and Carbon dioxide into this


Plant's gather the sun's energy with light absorbing molecules called?


Plants take in the sun's energy by absorbing what?


The stroma is the space that surrounds this

Thylakoid Membrane

Where light-dependent reactions take place

Thylokoid Membrane

Where photosynthesis I and II are found

Light Dependent reactions

Another name for the Calvin Cycle

High Energy Sugars

A product of the Calvin Cycle

Water,temperature, and light intensity

Things that effect the rate of photosynthesis


Requires light, Water, carbon dioxide, and chlorophyll

Rate of Photosynthesis

Decreases when the weather becomes very cold

Van Helmont

Concluded that plants gain most of their mass from water alone


Organisms such as hawks and leopards that obtain energy from the foods the consume

High Energy Sugars

Photosynthesis uses energy of sunlight to convert water and arbon dioxide into oxygen and this


Found that plants produce oxygen bubbles only in the presence of light
