Photosynthesis and Cellular Respiration Worksheet

If you’re looking for a photosynthesis and cellular respiration worksheet then you’ve come to the right place! First I’ll introduce you to some fabulous, time tested resources that I’ve already prepared to make lesson planning one step easier. Next, I’ll give you some ideas on ways to use these resources to improve your teaching and to make learning fun for you and your students.

First, I have the Reactants and Products of Photosynthesis and Cellular Respiration. This one page review comes in both PDF and digital formats with answer key for your convenience. The primary objective of this resource is to teach students the meaning of the words product and reactant and to give them practice identifying them in various chemical reactions.

If you need a review of all the key concepts from your unit, try the Photosynthesis and Respiration Graphic Organizer. This resource is designed to help students compare and contrast photosynthesis and respiration, including the products and reactants of each and where each takes place within a cell.

Finally, the Photosynthesis and Respiration Guided Reading is an excellent resource to fill in any gaps your students may have missed during the day’s lesson. It also supports literacy in science by giving students the opportunity to own their learning by working through some important concepts on their own.

Let me try to convince you that the products I’m offering are worth your hard earned cash. (Or you can always apply for reimbursement through your school.)

I work hard so you don’t have to. Finding useful resources for your lesson is a lot of work. Making them is even more work. Whenever I can, I always trade money for time. A couple dollars to reimburse another classroom teacher for their efforts in creating valuable resources is seen as a fair trade according to thousands of positive reviews.

My resources are high quality. Most of my resources come in both PDF and digital format to support you in face to face, virtual, or hybrid learning models. Having multiple representations is always useful for differentiation. My resources also include an easy to use answer key and high quality image, graphics, and explanations where needed.

All of my resources are guaranteed. That means that if you’re unhappy with your purchase, I will fully refund you. My email is listed on the last page of every resource. All you have to do is send me a quick note about your experience and I can resolve the issue or refund you.

How to Use the Photosynthesis and Respiration Worksheet

Emergency Sub Plans

If you’re feeling a little sick and need a day to rest, either the Photosynthesis and Respiration Guided Reading or the Reactants and Products of Photosynthesis and Cellular Respiration would be an excellent way to allow students to work on their own (either digitally or on paper) without a lot of speaking required on your part. To make things even better, you’ll be supporting literacy in the classroom too!

Independent Work Station

Stations are a great way to make a long class feel shorter or a large class feel smaller. Split your class into groups based on the number of stations you have. One of your stations can be a setting that allows you to work closely with some students, and other groups should have work that can be completely independently. This will give you the opportunity to give the students who need support your full attention. Don’t forget that you can do stations online too!

Flipped Classroom Pre-Reading

I’m a huge fan of the flipped classroom model because it gives students ownership of their own learning. By assigning my the Photosynthesis and Respiration Guided Reading as a pre-reading, you save valuable class time in which you would have been explaining the concepts from scratch. Don’t be afraid to hold your students accountable by assigning students to digest the “meat” of the lesson ahead of time.

Close Reading Strategies

Close reading is an essential skill that must be taught in all classrooms. Time and time again, students are showing that they are not prepared to read college level texts. Spoon feeding them isn’t going to solve this issue. We absolutely must increase the rigor in our classrooms when it comes to literacy, and teaching reading strategies is the path that will take our students where they need to be.


Differentiation can feel like a huge burden for teachers. How are we supposed to create several different variations of the same lesson or activity? In reality, we probably can’t. What we can do, though, is provide independent work packets for students who are not able to be present for direct instruction. We can make choice boards in which students will most likely differentiate for themselves, we can provide extension activities for early finishers, and we can provide extra practice for students who aren’t showing mastery.


I know as teachers we hear a lot about the benefits and drawbacks of homework. Whether or not you’re in support of homework, I’d just like to point out that it’s there as an option. ¯\_(ツ)_/¯

Interactive Notebooks

Interactive notebooks are unmatched in their ability to keep students organized and work in one place. I’m a huge fan of shrinking my worksheets down to fit in an interactive notebook. Sometimes I print 2 in one, cut them in half and just glue the sheets directly into pages of a notebook. Other times I transform multi-page PDFs into mini books (use these simple instructions if you’d like to try it) and insert the entire thing into a notebook.


Whether summative or formative, consider using these resources as an option for assessment.

NGSS Standards Supported by the Photosynthesis & Respiration Worksheet

MS-LS1-6 Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms. Emphasis is on tracing movement of matter and flow of energy. Assessment does not include the biochemical mechanisms of photosynthesis.

MS-LS1-7 Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism. Emphasis is on describing that molecules are broken apart and put back together and that in this process, energy is released. Assessment does not include details of the chemical reactions for photosynthesis or respiration.

My teaching resources have already benefitted the learning of over half a million students. Please pin the image below to help me expand my reach and for others to find this food chains and food webs worksheet with answers.
