the Electromagnetic Spectrum

What is the entire range of possibilities for electromagnetic waves called?

white light

What light is a combination of all colors in the Visible Spectrum?

rainbow

What is an example of white light that has been separated into a continuous spectrum of colors?

wavelengths

Fill in the Blank: The names of colors are assigned in order of their blank.

visible spectrum

What are the only wavelengths humans can see called?

Shorter

Fill in the Blank: Blank wavelengths have more energy.

less

Fill in the Blank: Longer wavelengths have blank energy.

Red, orange, yellow, green, blue, indigo, and violet

violet

What color in the visible spectrum has the most energy?

red

What color in the visible spectrum has the longest wavelengths?

red

What color in the visible spectrum has the least amount of energy?

thylakoid, granum, and stroma

What are the three main parts of a chloroplast?

a grana

What is a stack of thylakoids called?

the stroma

What is the space around the thylakoids called?

transmitted, reflected, and absorbed

What are the three different kinds of light in a chloroplast?

plant pigments

What absorb the light in chloroplasts?

Absorbed

Fill in the Blank: Blank light waves is the kind of light energy used in photosynthesis.

violet and blue

What colors of the visible spectrum are absorbed most?

green and yellow

What colors of the visible spectrum are absorbed least?

orange and red

What colors of the visible spectrum are absorbed only a little(not the most, not the least)?

green

What main color is not important in photosynthesis?

Black

What color has no wavelengths and no light?

Black

What color reflects nothing and absorbs all colors of the visible spectrum?

photosynthesis

Fill in the Blank: Increase of blank corresponds with the wavelengths absorbed.

yellow and green

What two colors are the least important in photosynthesis?

Water is split and oxygen is released

What is the first stage of the Light reaction in photosynthesis?

NADP picks up the hydrogen from the first stage and makes NADPH

What is the second stage of the Light reaction in photosynthesis?

ADP plus a phosphate uses light energy to convert into ATP

What is the third and last stage of the Light reaction in photosynthesis?

ATP

What is the energy that all living things use called?

in the thylakoids

Where does the Light reaction take place?

requires light

What does Light reaction mean?

6H2O is used and 6O2 is released

the leaves

In what organ is glucose formed in photosynthesis?

the roots

Where does the glucose travel to in photosynthesis?

diffusion

By what process does glucose travel to the roots and is stored?

the stomata

Where does the oxygen in photosynthesis exit the leaf?

by diffusion

By what process does oxygen exit the leaf in photosynthesis?

in daylight

When does the Light reaction occur?

glucose

What is the main energy containing compound produced by green plants?

the leaves

What are the main photosynthetic organs of a plant?

in the day

When are guard cells open?

in the night

When are guard cells closed?

by swelling with water

How do guard cells open?

it is absorbed, reflected, or transmitted

When light hits any object, what then happens to the light?

green is reflected and the rest of the visible spectrum is absorbed

What happens to light when it hits a plant?

red orange yellow blue indigo and violet

What kind of light is important to plants?

through the light reactions

How is the important light trapped by plants?

water is split and ATP is formed

Name two specific reactions performed by plants using the light important to them.

palisade, spongy, and guard

Which leaf cells contain chloroplasts?

water

Where does the oxygen which plants release to the atmosphere initially come from?

ATP, glucose

Fill in the Blank: The energy from the light absorbed by plants is converted and stored as blank. This is then used in another reaction, so the energy is then transferred and stored in blank.

needs carbon dioxide
