How Plants Make Their Organic Molecule Worksheet PDF
Name: ______________________ Date: _______________
Instructions: Read the following information about how plants produce their organic molecules through photosynthesis, and complete the exercises below.
Introduction:
Plants are amazing organisms that can make their food using sunlight, carbon dioxide, and water. This process is called photosynthesis. The main organic molecule produced by plants is glucose, a type of sugar that provides energy.
1. **Read and Understand**
Plants use sunlight to convert carbon dioxide and water into glucose and oxygen. This process occurs mainly in the leaves of the plant, where chlorophyll (the green pigment) captures sunlight. Here’s the basic equation for photosynthesis:
Carbon Dioxide + Water + Sunlight → Glucose + Oxygen
2. **True or False**
Read each statement below. Write “True” if the statement is correct and “False” if it is not.
a) Photosynthesis occurs in the roots of the plant. ______
b) Chlorophyll helps plants absorb sunlight. ______
c) Oxygen is a byproduct of photosynthesis. ______
d) Plants only need carbon dioxide to perform photosynthesis. ______
3. **Fill in the Blanks**
Complete the sentences using the words from the box below.
(Chlorophyll, Glucose, Sunlight, Carbon Dioxide, Photosynthesis, Water)
a) The process by which plants make their food is called __________.
b) Plants need __________ and __________ to perform photosynthesis.
c) The green pigment that helps absorb sunlight is called __________.
d) The main product of photosynthesis is __________.
4. **Match the Terms**
Match the terms in column A with their corresponding descriptions in column B.
Column A Column B
1. Sunlight a. The gas that plants take in during photosynthesis
2. Glucose b. A sugar that provides energy for the plant
3. Photosynthesis c. The process by which a plant makes its food
4. Carbon Dioxide d. The energy source for photosynthesis
5. **Short Answer Questions**
Answer the questions in complete sentences.
a) Why is sunlight important for photosynthesis?
_____________________________________________________________________________
b) What role does chlorophyll play in the process of photosynthesis?
_____________________________________________________________________________
c) How do plants release oxygen into the atmosphere?
_____________________________________________________________________________
6. **Drawing Activity**
Draw a simple diagram of a plant showing where photosynthesis takes place (label the leaves, sunlight, carbon dioxide, and chlorophyll).
7. **Fun Fact**
Did you know that a single mature tree can produce enough oxygen for at least two people in one year?
