INTRODUCTION
This worksheet complements the animation series Photosynthesis.
PROCEDURE
1. This animation series contains seven parts. Read the questions below for each part before watching it.
2. After watching each part, answer the questions in the spaces provided.
3. After completing all seven parts of the animation, answer the summary questions in Part 8.
QUESTIONS
PART 1: OVERVIEW
1. Which of the following kinds of organisms do photosynthesis? Select all that apply.
_✓ plants _fungi _ _animals _✓ _algae _ _all bacteria _✓ _some bacteria
2. What is the overall purpose of photosynthesis?
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize.
The light energy that absorbs from the sun and converts into chemical energy, produces glucose molecules that
they store in their leaves for later consumption.
3. On Diagram 1, fill in the labels with photosynthesis’s main inputs and outputs of matter and energy.
PART 2: CHEMICAL PROCESS
1. Complete the following sentence.
Photosynthesis is a set of chemical reactions in which light energy is converted to
chemical energy.
, 2. On Diagram 2, fill in the labels with the following descriptions. Some of the objects have multiple labels.
● water (H2O)
● carbon dioxide (CO2)
● oxygen (O2)
● G3P (sugar)
● electron acceptor
● electron donor
● carbohydrates
● energy input
PART 3: LEAF STRUCTURE
1. In what plant structures does photosynthesis occur? Make your description as specific as you can.
Photosynthesis occurs in the chloroplast where the thylakoid membranes lie and these membranes contain
chlorophyll.
2. On Diagram 3, complete the following tasks.
a) Draw how CO2 gets into
the leaf.
b) Draw how O2 gets out of
the leaf.
c) Label the name of the
structure through which
these gases pass.
3. What structure is used to transport organic molecules from the leaf to other parts of the plant?
The vascular tissue transports organic molecules like water, minerals, and sugars to the different parts of the
plant.
4. Why are leaves green?
A green pigment in chloroplasts called chlorophyll absorbs all colors except green which is reflected and gives
plants a green appearance.
