Photosynthesis: Making Energy

Name Date Period

Chloroplasts

Photosynthesis is a process in which sunlight energy is used to make glucose. The site of photosynthesis is in the chloroplast – an organelle found in the leaves of green plants. The main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy. Chloroplasts contain the pigment, chlorophyll. Chlorophyll absorbs most of the colors in the color spectrum, and reflects only green and yellow wavelengths of light. This is why we see leaves as green or yellow – because these colors are reflected into our eyes.

1. What is photosynthesis?

2. Where does photosynthesis occur?

3. What are chloroplasts and where are they found?

4. What are the two main functions of chloroplasts?

5. Why do most leaves appear green?

6. What is the primary pigment found in the chloroplast?

Photosynthesis

Glucose is another name for sugar. The molecular formula for glucose is C6H12O6. Plants make sugar by using the energy from sunlight to transform CO2 from the air with water from the ground into glucose. This process, called photosynthesis occurs in the chloroplast of the plant cell. During this process, oxygen (O2) is created as a waste product and is released into the air for us to breathe. The formula for photosynthesis is:

(reactants)            (products)
CO2 + H2O + sunlight ----> C6H12O6 + O2

This formula says that carbon dioxide + water molecules are combined with the energy from sunlight to produce sugar and oxygen. The reactants in photosynthesis (what is used) are CO2, water and sun. The plant gets water from the ground through its roots. The plant collects carbon dioxide from the air. Much of the carbon dioxide comes from living organisms that exhale (breathe it out) it, but some also comes from factory smokestacks and car fumes.

7. What is the formula for photosynthesis?

8. What three things are used to make glucose in photosynthesis?

9. Where does the water come from?

10. Where does the water enter the plant?

11. Name 3 some sources of CO2.

12. What type of energy does the plant use to convert CO2 and H2O into sugar?

The products are glucose and oxygen. The glucose produced is used by the plant for energy and growth. We also use this glucose by eating plants. The oxygen produced is released into the air for us to breathe. Photosynthesis is essential for all life on earth, because it provides food and oxygen. Plants are considered autotrophs because unlike us humans, they can make their own food using this process.

13. What is produced in photosynthesis?

14. What is the glucose used for?

15. What is the oxygen used for?

16. Here are three different ways to visualize the photosynthesis reaction: Is it easier for you to understand the reaction by using pictures, words, or symbols (see above)? Why?

Photosynthesis in pictures | Photosynthesis in words | Photosynthesis in symbols

Carbon dioxide and water combine with sunlight to create oxygen and glucose.

CO2 + H2O + sunlight → C6H12O6 + O2

CO2 + H2O + sunlight → C6H12O6 + O2

Essential Question: Describe, using scientific terms, how plants turn sunlight into energy? Make sure to refer to the chemical equation to photosynthesis and discuss the reactants and products.

What a Photosynthesis Worksheet Is and when to use it

The Photosynthesis Worksheet is a structured, fillable educational template used to teach and assess plant photosynthesis concepts and lab procedures. Typical sections include objectives, key vocabulary, labeled diagrams, stepwise reaction summaries (light-dependent and Calvin cycle), data tables for experimental trials, and targeted questions for analysis. Teachers and lab instructors use the worksheet to standardize activities, collect measurable student responses, and document observations. The worksheet can be delivered on paper or electronically and adapted for different grade levels by adjusting task complexity and assessment depth.

HIPAA Risk: Applicable if health data included
Lost Records: Missing backups can impair grade verification
Data Entry Errors: Incorrect values skew results and grades
Authentication Weakness: Anonymous submissions may be misattributed
Accessibility Gaps: Poor accessibility may violate district policy

Real-world classroom scenarios

Two concise examples show typical implementation and outcomes for different class settings.

High School Lab

A biology teacher assigns the worksheet for a light intensity experiment

  • students complete three trials and record oxygen output
  • after grading, the teacher exports CSV data to the LMS to analyze class-level trends and plan remediation for common errors.

Remote Learning

A blended course uses the electronic worksheet with image upload for leaf cross-sections

  • students attach photos and annotate diagrams
  • the instructor reviews time-stamped submissions and provides targeted feedback through the LMS comment system.

Tips to streamline completion and ensure reliable results

Apply these practical practices to reduce errors and improve the educational value of each worksheet.

Pre-fill Stable Data
Populate immutable fields (teacher name, experiment title, rubric links) before distribution so students focus on observations; this reduces inconsistent entries and eases grading reconciliation.
Standardize Units
Require specific units in the data table (e.g., mL, seconds) and validate entries digitally where possible to prevent unit mismatches that impede analysis.
Require Photos or Screenshots
When practical, ask for image attachments of setups or results to improve reproducibility and reduce disputes about observed phenomena or measurement technique.
Backup and Archive
Export completed worksheets and audit logs to secure cloud storage and retain copies according to district and federal retention rules to support audits and grading appeals.
