Photosynthesis Flashcards
1
Q
Photosynthesis
A
- the most important chemical process on earth
- the process which plants use energy from the sun to make sugars from carbon dioxide and water
2
Q
What does Photosynthesis Provide?
A
food and energy for all living creatures who eat plants
3
Q
Who relies on Photosynthesis?
A
Plants
4
Q

Color
A
- the color of an object is due to the way objects interact with light
- the color perspective is the wavelength of light that is reflected and the rest of the wavelengths are observed
8
Q
Pigments
A
molecules (protiens) that absorb light energy and determine the color of an object
9
Q

A
Ture
10
Q
Where are pigments located in the Plant?
A
Chlorophyll
11
Q
Chlorophyll A
A
- absorbs blue-violet and red light, reflects green light
- Primary Pigment in Photosynthesis
12
Q
Chlorophyll B
A
- absorbs blue and orange light, reflects yellow - green
- assist chlorophyll a in absorbing light energy
13
Q
Carotenoids
A
reflect yellow-orange/brown, absorbs everywhere else
14
Q
Where does photosynthesis occur?
A
Chloroplasts
15
Q
Do Plants have many pigments?
A
Yes, that accounts for the variation of colors in plants.
