7th grade photosynthesis worksheet

Photosynthesis and Respiration

Photosynthesis and respiration are two vital processes that occur in living organisms . Photosynthesis is the process by which green plants, algae , and some bacteria convert light energy , carbon dioxide , and water into glucose and oxygen . Respiration , on the other hand, is the process by which cells break down glucose and other organic compounds to release energy that is used for cellular activities.

Photosynthesis

• Definition: Photosynthesis is the process by which green plants, algae , and some bacteria convert light energy , carbon dioxide , and water into glucose and oxygen .
• Equation: 6CO 2 + 6H 2 O + Light energy → C 6 H 12 O 6 + 6O 2
• Key Factors: Light , chlorophyll, carbon dioxide , and water are essential for photosynthesis to occur.
• Organisms : Photosynthesis occurs in green plants, algae , and some bacteria .

Respiration

• Definition: Respiration is the process by which cells break down glucose and other organic compounds to release energy that is used for cellular activities.
• Equation: C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O + Energy
• Key Factors: Oxygen and glucose are essential for respiration to occur.
• Organisms : Respiration occurs in all living organisms , including plants, animals, and microorganisms .

Study Guide

Here are some key points to remember when studying photosynthesis and respiration :

• Understand the chemical equations for photosynthesis and respiration and the products formed in each process.
• Learn about the organelles involved in these processes, such as chloroplasts in photosynthesis and mitochondria in respiration .
• Explore the factors that affect the rate of photosynthesis , such as light intensity, carbon dioxide concentration, and temperature .
• Understand the different types of respiration , including aerobic respiration (with oxygen ) and anaerobic respiration (without oxygen ).
• Explore the interconnected nature of photosynthesis and respiration in the carbon cycle and energy flow within ecosystems .

By understanding the intricacies of photosynthesis and respiration , you will gain valuable insights into the fundamental processes that sustain life on Earth .

Check out the photosynthesis worksheets included:

Diagram and reading passage with questions.

Introduce your students to an overview of photosynthesis with a diagram they will label. Then, use the provided reading passage to have students read, highlight, or annotate the section to become more familiar with the photosynthesis process. The corresponding questions will test their understanding. Plus, both the diagram and reading questions can serve as awesome review tools before test time!

We’re loving this unique and fun activity! Students will start in the top left and answer each question in the green boxes. Once they select the correct answer, they’ll shade in that pathway to lead them to the next question to work on.

Scavenger Hunt

Get students moving! Cut out the question cards and place them around the room. Students can start at any station and use their answer sheet to write out any work and their answer. Based on the answer they gave, they’ll find the next station to go to.

Cut and Paste

Ask students to cut out the answer cards and they’ll work to match them in the correct space within the chart. Once their answers are finalized, they can paste them in! You can even ask students to color-code or draw a diagram on the answer cards to help them remember.
