About photosynthesis notes
GoConqr OriginalWhat the photosynthesis notes cover
The notes offer several ways into this unit. One Photosynthesis note introduces the process and its chemical equation, while another describes chloroplasts, light harvesting and the two reactions. Other notes cover chlorophyll, leaf adaptations and uses of glucose.
For a closer look at the reactions, there are notes titled Light Dependent Stage and Light Independent Reaction. The list also includes Photochemical reactions and Calvin cycle and a note outlining an experiment to show that photosynthesis produces starch.
Using notes to revise
Start with the Photosynthesis note that includes the chemical equation for an overview, then read a note on the reaction you want to study in more detail. Write down the steps in your own words and check them against the note. When you want a different view, switch to a mind map on the unit page, or use a quiz to check what you remember.
Browse the notes and pick a topic to explore.
Frequently asked questions
Which note is a good place to start?
The Photosynthesis note that introduces the process and its chemical equation is a useful starting point for an overview. From there, the notes on chloroplasts or leaf adaptations offer more detail, while Light Dependent Stage focuses on one part of the process.
What topics do the notes cover?
The list includes notes on chloroplasts, chlorophyll, leaf adaptations and uses of glucose. It also has notes on the light-dependent and light-independent reactions, as well as an outline of an experiment to show that photosynthesis produces starch. Different notes focus on different parts of the unit.
Are these notes free to use?
Yes. Every note listed here is free to open and study without an account. The resources were made by GoConqr users. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes.
