How Do Chloroplasts Capture Energy from the Sun?

Plant cells and some algae contain an organelle called the chloroplast. Chloroplasts are concentrated in the leaves of plants and allows plants to harvest energy from sunlight, a process called photosynthesis. Pigments in the chloroplasts absorb sunlight and use this energy to combine carbon dioxide and water to make glucose and oxygen. The complete reaction is:

Plant cells can use this process to manufacture glucose, a simple sugar. Some of the glucose is used immediately for cellular respiration, where it is converted to a high energy compound called ATP. You might recall from studies of the cell, that the process of creating ATP occurs in the mitochondria. Glucose that is not used right away is packaged as carbohydrates or fats and then stored in the roots, seeds, and fruits. All autotrophs can make their own food in this way, unlike heterotrophs, which must consume food. When you eat a potato, you are eating the carbohydrates that the plant created from sunlight.

Sun & Energy = yellow

Carbon Dioxide = red

Water = light blue

Photosynthesis = green

Respiration = purple

Glucose = dark blue

Storage Products = brown

ATP = orange

Oxygen = pink

Teaching Photosynthesis and Cell Respiration with Hands-On Activities

What other two topics during the year frighten the students (and sometimes the teacher) more than photosynthesis and cell respiration? These two units really can be daunting. They don’t lend themselves to a lot of fun activities and often the teacher feels stuck listing chemical reactions on a powerpoint, using vocabulary that might as well be in Cantonese. Oxidation-reduction reactions? Phosphofructokinase? RuBisCO? Pyruvate? These words really mean less than nothing to the average 14-18 year old. What are some ways we can make this unit more approachable, more fun, and more useful in promoting the general understanding of how life works?

As a teacher, there are a few things to decide as you approach this unit:

  1. How much detail do you show them and how much detail do you expect them to remember?

How much detail you go into is up to you, but when teachers only show the bare minimum, I think fewer students understand the processes. If you just show them a mysterious blackbox called “glycolysis”, tell them that glucose and NAD+ go in, and pyruvate and ATP and NADH comes out, students can only memorize this short fact list. Meaningless.

My strategy to help students appreciate these processes and actually UNDERSTAND them instead of memorize a reaction is to show them some details, but only ask questions about the main ideas.

For example, I do show them all the steps of glycolysis, but I really won’t ask them more than the net reaction and a few key facts. I do want them to be able to follow the carbon atoms in a diagram from glucose all the way to carbon dioxide. I do want them to know that energy is needed in the first few steps to “kickstart” the reactions, because this helps them understand thermodynamics and kinetics later when they take chemistry/physics. I do want them to know that every reaction is catalyzed by a unique enzyme, because the enzyme pathway concept is all throughout biology. Will they need to memorize the difference between glyceraldehyde-3-phosphate and dihydroxyacetone phosphate? No way. The key is for them to UNDERSTAND, not to memorize.

I always say that if teaching something is boring to me, it is going to be really boring to my students. If I am having fun, fun is contagious and they will too! There are a bunch of ways to deliver information to students and in my classroom, I find PowerPoint to be the least effective and the most boring, especially in this unit and especially with lower level students.

Here are a few ways I like to help my students learn in these two units:

A. Animations, animations, animations! Animations really do work wonders in helping students understand and really see any process in biology and especially these processes. Here is a brief list of the best photosynthesis and cell respiration animations I have found on the web (These work as of January 15, 2016).

Another light reactions animation – the intro music is quite eery and students are usually entertained: http://vcell.ndsu.edu/animations/photosynthesis/movie-flash.htm

BEST ATP SYNTHASE ANIMATION EVER! <– All caps because it is THAT GOOD!

B. Diagrams! Good diagrams are so important for a multitude of reasons. First, they can contain the information students need to know. Second, by examining diagrams, students learn how to interpret complex diagrams. Interpreting diagrams is a reading skill that is important in many career fields. It’s great if you can get a good diagram for students to keep in their notebooks, one that isn’t too complex yet not too simple. Which leads me to the next topic…

C. Hands-on Activities! I always wished when I was teaching that I had some sort of hands-on activity, some interactive materials for my students to use while they learned about photosynthesis and respiration. So I created some! In these activities, students create their own diagram for each process: Glycolysis, Citric Acid Cycle, Oxidative Phosphorylation, Light Reactions, and Light Independent Reactions (Calvin Cycle).

Each of these activities was designed to allow students to color or cut-and-paste while they read a 2 page reading and answer some questions. The activity leads them through each step and question the order in which they complete the reading and activity makes each process really more approachable. Here are some unique features of this set:


Geological evidence on the origin of photosynthesis

The advent of photosynthesis is known from geological studies to be a very ancient event. The earliest evidence for biological carbon fixation was dated to 3.8 billion years ago (or Giga-annum, Ga) [5, 6] from the isotopic composition of sedimentary rocks. The best known fossil evidence of the earliest photosynthetic forms of life has been dated to 3.5 Ga and was found to contain filamentous cellular structures [7, 8]. From their morphology alone, Schopf and co-workers [7, 8] proposed that these structures were oxygen-evolving cyanobacteria. This finding is significant in that it suggests that photosynthetic organisms were the earliest forms of life on Earth and that oxygen-evolving photosynthesis started in the early Archean age [9]. The finding remains controversial, however, because it is difficult to determine cell physiology on the basis of the shape of the structures in ancient microfossils. More recently, Brasier et al. [10] challenged the early interpretation of the microfossils by suggesting (using data from electron microscopy, digital imaging and Raman spectroscopy) that the structures were in fact artifacts of amorphous graphite. However, emerging geochemical studies [11, 12] seem to have reconfirmed the biogenic nature of the microfossils and thus reversed the conclusion of Brasier et al. [10].

Despite the controversies surrounding the 3.5 Ga fossils, there are some other microfossils thought to be cyanobacteria that are more likely to be genuine, the oldest of which were dated to 2.6-2.7 Ga by more reliable biomarkers [13, 14]. This timing is significant because it predates slightly the early rise of oxygen on Earth, which was about 2.3 Ga [15–17]. Recently, Tice and Lowe [1] showed additional evidence of photosynthetic carbon fixation by filamentous microbial mats found in 3.4 Ga cherts (flint-like sedimentary rocks) in completely anoxic environments. Their geochemical analysis further ruled out the possibility that the primary electron donor for the carbon fixation could be H2O (as used by plants), Fe 2+ or H2S. Instead, the primary electron source for this type of photosynthesis is most likely to have been hydrogen, which was abundant in the atmosphere in the early Archean age. The result is consistent with the view that the early photosynthesis was most likely to have been carried out by anoxygenic photosynthetic bacteria rather than cyanobacteria.


Activities for learning about photosynthesis for kids

Here are some of our printable resources for helping your child learn more about photosynthesis.

Science
Activity #1: As mentioned, one of the reasons that photosynthesis is so important to all life on earth, is that it is found at the bottom of all food chains and food webs. Producers rely on photosynthesis to create their own food. Print our Food Chain activity sheet and cut out the life forms. Then choose a few to create your own food chain. Be sure to label the producers, consumers, and decomposers!

Activity #2: We’ve described the process that a plant goes through to produce its own food. Print our Photosynthesis Process worksheet and label the steps that take place during photosynthesis.

Activity #3: Be a scientist and explore photosynthesis with an experiment. Download our Photosynthesis Experiment pages and follow the directions. Use whatever materials you can find at home.
