Name:
Photosynthesis Uses Light To Make Energy
Directions: Use online activity 8.1 to explore photosynthesis. Note that there are a total of seven pages
to study. Please answer the questions or complete the task listed on the front and back of this sheet.
PAGE 1
Move your mouse over the picture below and find eight items that are indirect products of
photosynthesis. Then use the chart below to list each item and describe why it is a product of
photosynthesis.

PAGE 2 –3
Scroll your cursor over the cross section of the leaf. Identify the location of the epidermis, mesophyll,
stomata, vein, air spaces, in the diagram of a cross section of a leaf below. Next to each label, identify
the purpose of each part of a plant leaf. Draw a star to indicate where there is high rate of sugar
synthesis, draw a circle where there is a medium rate of sugar synthesis, and draw a ‘X’ where there is a
low level of sugar synthesis.
PAGE 4
Scroll your cursor over the picture of the cell. Then answer each question.
1. Where in a plant cell is sugar production the highest?
2. Where in a plant cell is there a moderate level of sugar production?
3. List at three other places in a plant cell where there is little if any sugar production
PAGE 5
Draw a picture of a chloroplast. Label the inner membrane, the outer membrane, the thylakoid, and the
thylakoid space. Draw a star to indicate where there is high rate of sugar synthesis, draw a circle where
there is a medium rate of sugar synthesis, and draw a ‘X’ where there is a low level of sugar synthesis.
PAGE 6
Study the diagram and answer the questions.
1. What two processes occur in a chloroplast?
2. Study the equation for photosynthesis: 6CO2 + 6H20
A.
B.
C.
D.
C6H12O6 + 6O2
Circle the molecules needed for the light reaction.
Draw a line under the molecule produced in the light reaction
Put a box around the molecule needed for the Calvin Cycle.
Put a triangle around the molecule produced in the Calvin Cycle
PAGE 7
Watch the animation and answer the question below.
1. During the light reaction the sun’s energy is used to split molecules of water. What kind of gas is
produced?
2. During photosynthesis, what process produces ATP and NADH?
