Exercise 1
Step 1
1 of 2
Chlorophyll is the green pigment found in plants. This pigment is mainly responsible for capturing the sunlight and use it for photosynthesis.
Result
2 of 2
A. chlorophyll
Exercise 2
Step 1
1 of 2
Light-dependent reactions, which occur in the thylakoid membranes of a chloroplast, is the first stage of photosynthesis. In this stage, ATP and NADPH are produced and these compounds are used by the Calvin cycle for producing glucose. Therefore, sugar is not produced by light-dependent reactions.
Result
2 of 2
B. sugars
Exercise 3
Step 1
1 of 2
Photosynthesis uses the energy from the sun by converting carbon dioxide and water into glucose and oxygen. The equation for photosynthesis is shown as follows:

carbon dioxide + water $rightarrow$ glucose + oxygen

6CO$_{2}$ + 6H$_{2}$O $rightarrow$ C$_{6}$H$_{12}$O$_{6}$ + 6O$_{2}$

Result
2 of 2
A. water + carbon dioxide $rightarrow$ sugars + oxygen
Exercise 4
Step 1
1 of 2
Chlorophyll can absorb the blue-violet and red regions of the visible spectrum when they photosynthesize using light. Since green is the color in which a chlorophyll could not absorb, the green light is reflected. As a result, the leaves of the plant appear green.
Result
2 of 2
C. green
Exercise 5
Step 1
1 of 2
Light-dependent reactions, which occur in the thylakoid membranes of a chloroplast, is the first stage of photosynthesis. In this stage, the first step is the absorption of light energy. The chloroplast is mainly responsible for capturing the sunlight.
Result
2 of 2
E. absorption of light energy
Exercise 6
Step 1
1 of 2
Light, which is absorbed by the chlorophyll, carbon dioxide, and water are all the essential things needed by the plants to process photosynthesis. The production of oxygen and sugars is a result of photosynthesis.
Result
2 of 2
C. oxygen
Exercise 7
Step 1
1 of 2
Among all the other pigments, the yellow-green pigment is the nearest one from the original spot of extract. Therefore, this pigment traveled the shortest distance.
Result
2 of 2
D. yellow-green
Exercise 8
Step 1
1 of 2
According to the results obtained in the experiment, there were several pigments in the spinach leaves. The pigments found are yellow-green, blue-green, yellow, and yellow-orange.
Result
2 of 2
B. contain several pigments
Exercise 9
Step 1
1 of 2
The chloroplast contains the thylakoid membranes which houses the photosynthetic pigments such as chlorophyll.
Result
2 of 2
D. chloroplasts
