TERM 1
Photosynthesis
DEFINITION 1
a process that converts light energy into energy stored in the
bonds of simple sugars. The light energy drives the reactions
that reduces carbon dioxide to sugar by using the electrons
from water as it is "split" and oxygen is released. Those
sugars can then be used to build more complex molecules.
TERM 2
What are the requirements for
photosynthesis?
DEFINITION 2
H2O, CO2, chlorophyll and light energy
TERM 3
What are the products of photosynthesis?
DEFINITION 3
ATP, NADPH, O2, and glucose
TERM 4
What did you use to show CO2 is consumed?
DEFINITION 4
The Phenol red experiment
TERM 5
What was the indicator? What did it show?
DEFINITION 5
The indicator was Phenol red. It is used to show when CO2 is
present. When it is not present, it is red. When you add O2 it
turns yellow.

Photosynthesis

a process that converts light energy into energy stored in the

bonds of simple sugars. The light energy drives the reactions

that reduces carbon dioxide to sugar by using the electrons

from water as it is "split" and oxygen is released. Those

sugars can then be used to build more complex molecules.

TERM 2

What are the requirements for

photosynthesis?

DEFINITION 2

H2O, CO2, chlorophyll and light energy

TERM 3

What are the products of photosynthesis?

DEFINITION 3

ATP, NADPH, O2, and glucose

TERM 4

What did you use to show CO2 is consumed?

DEFINITION 4

The Phenol red experiment

TERM 5

What was the indicator? What did it show?

DEFINITION 5

The indicator was Phenol red. It is used to show when CO2 is

present. When it is not present, it is red. When you add O2 it

turns yellow.

Which turned from yellow back to its original

red color? and why?

The tube in the light turned back red when photosynthesis

occurs after is consumed CO

TERM 7

Why doesn't the phenol red change in the

other tubes?

DEFINITION 7

Photosynthesis didn't occur. Not all requirements were met.

The ones in the dark didn't have the light energy requirement

and the others had no plants, so no chlorophyll.

TERM 8

Is CO2 used in the light reactions or the

Calvin Cycle?

DEFINITION 8

Calvin Cycle

TERM 9

What experiment showed oxygen is

produced?

DEFINITION 9

Geranium Leaf experiment

TERM 10

What indicator was used? What was it used

for?

DEFINITION 10

Iodine; to find starch

Why can iodine be used to test for

photosynthesis?

starch turns blue while sugar is being used to create

photosynthesis
