Photosynthesis removes______ from the Atmosphere.

Carbon Dioxide (CO2)

An important by-product of photosynthesis needed by aerobes.

Oxygen (O2)

Ecological role played by all autotrophs.

Producers

Kingdom in which all members are autotrophic.

Plants

Removal of carbon dioxide from the atmosphere helps combat _________

Global warming & the “greenhouse effect”

Electromagnetic energy that we can see is called the:

Visible Spectrum

The visible spectrum includes the colors of light ranging from ______ to ______

Violet to Red

Plants do not use which color of light in photosynthesis?

Green

Which wavelength has greater energy, Blue or Orange?

Blue

Predict what would happen if suddenly only green light reached the earth

Photosynthesis would stop Photosynthesis would stop! Plants would die, we would run out food and O2, temperatures would rise

The two stages of photosynthesis are the:

Light Reactions 2) Dark reactions or the Calvin Cycle

Raw material used in the Light Reactions

Water

Waste product produced from the Light Reactions

Oxygen (O2)

Raw material used in the Dark Reactions

Carbon Dioxide (CO2)

Important Enzyme used to help join CO2 with RuBP

Rubisco

Structure where photosynthesis takes place in eukaryotic cells.

Chloroplasts

The Light Reactions take place on membranes called the:

Thylakoid membranes

The _______ is to a chloroplast as the cytoplasm is to a whole cell.

Stroma

Tissue in leaves that performs photosynthesis

Mesophyll

The Calvin Cycle takes place in the ________ of chloroplasts

Stroma

Plants control water loss by:

Closing stomata and by producing a waxy covering, the cuticle

Why does closing stomata inhibit photosynthetic rate?

CO2 can’t get in and O2 can’t get out

The end product of photosynthesis is:

PGAL (glucose is an OK answer)

Photorespiration occurs when:

Oxygen levels get too high

Name two adaptations that allow some plants to be productive during times of high temperatures.
