Captured: The Moment Photosynthesis Changed the World

This informational text resource is intended to support reading in the content area. Geologists have made an important discovery about the origins of photosynthesis. According to evidence in South African rocks, before organisms were using water as the electron source for photosynthesis, they were using manganese - these rocks formed in anoxic conditions, but contain oxidized manganese. This evolution of photosynthetic organisms, which released atmospheric oxygen, laid the groundwork for more complex life forms, such as animals, to come into existence.

Photosynthesis: The Calvin Cycle


This tutorial is a step by step explanation of what occurs in photosynthesis during the Calvin Cycle. It describes and uses visuals for the chemical reactions in this biochemical pathway. This challenging tutorial addresses the standard at a high level of complexity.

Photosynthesis: The Light Reaction


This tutorial shows and describes what occurs during the light reactions of photosynthesis which is the first stage of photosynthesis when plants capture and store energy from sunlight. In this process, light energy is converted into chemical energy, in the form of the energy-carrying molecules ATP and NADPH.

CAM Plants

This Khan Academy video explains how CAM plants fix carbon dioxide at night so they do not lose water by opening their stomata during the day.

C4 Photosynthesis

The Khan Academy video discusses how some plants avoid photorespiration by fixing carbon in the bundle sheath cells instead of the mesophylll cells.

Photorespiration

This Khan Academy video reviews the Calvin Cycle in C3 photosynthesis and discusses the reactants and products of this process. The video then describes photorespiration which is what occurs when the enzyme RuBisCO fixes oxygen instead of carbon dioxide and explains why this is considered an inefficient pathway for plants.

Photosynthesis: The Light Reactions

This Khan Academy tutorial explains in detail the process of the light reactions of photosynthesis including the importance of the thylakoid membrane and the products that are produced from this reaction.

Photosynthesis: The Calvin Cycle

This Khan Academy tutorial explains how the by-products from the light reactions of photosynthesis are used to produce sugar molecules in the Calvin Cycle.

The Simple Story of Photosynthesis and Food

Photosynthesis is an essential part of the exchange between humans and plants. Amanda Ooten walks us through the process of photosynthesis, also discussing the relationship between photosynthesis and carbohydrates, starch, and fiber -- and how the air we breathe is related to the food we ingest.

Nature's Smallest Factory: The Calvin Cycle

A hearty bowl of cereal gives you the energy to start your day, but how exactly did that energy make its way into your bowl? It all begins with photosynthesis, the process that converts the air we breathe into energizing glucose. Cathy Symington details the highly efficient second phase of photosynthesis -- called the Calvin cycle -- which converts carbon dioxide into sugar with some clever mix-and-match math.

MIT BLOSSOMS - Roots, Shoots, and Wood The topic of photosynthesis is a fundamental concept in biology, chemistry, and earth science. Educational studies have found that despite classroom presentations, most students retain their naïve idea that a plant's mass is mostly derived from the soil, and not from the air. To call students' attention to this misconception, at the beginning of this lesson we will provide a surprising experimental result so that students will confront their mental mistake. Next, we will help students better envision photosynthesis by modeling where the atoms come from in this important process that produces food for the planet. This lesson can be completed in 50-60 minutes, with the students working on in-class activities during 20-25 minutes of the lesson. As a prerequisite, students need an introductory lesson on photosynthesis, something that includes the overall chemical equation. If students have already studied the intracellular photosynthetic process in detail, this video can still be very helpful because students often miss the big picture about photosynthesis. Materials needed include red, white and black LEGO bricks (described in downloadable hand-out) or strips of red, white and black paper plus paper clips (directions provided in downloadable hand-out). In addition to class discussions, the major in-class activity of this video involves the students' modeling with LEGO® bricks or colored paper where the atoms come from in photosynthesis.
Cellular Respiration These animations show cell respiration as a big picture, and then go through the steps of cellular respiration: glycolysis, the Krebs cycle, and electron transport. Each animation is short and to the point.
