California Classroom Science » Virtual Photosynthesis Lab
In this lab we will examine photosynthesis, one of the two major processes by which most organisms convert energy from an unusable form to a usable chemical form (photosynthesis), and then convert that chemical energy into ATP, the energy currency of the cell (cellular respiration).
Go to the lab and follow the procedures there. Download your lab report form and fill it out as you move through the lab.
We begin with a definition of each process: Photosynthesis: Conversion of unusable sunlight energy into the energy locked inside the covalent bonds of glucose (a simple sugar you recall from previous labs). Carbon dioxide (CO2) and water (H2O) serve as the raw materials that the cells assembles into sugar (C6H12O6), with dioxygen (O2) given off (as a by-product).
Cellular Respiration: Transfer of the energy locked inside glucose (and sometimes other molecules) into the most readily usable energy for cells, Adenosine Triphosphate (ATP). Sugar and dioxygen are the starting products that produce carbon dioxide and water plus heat and ATP (“recharged” from the lower energy form, ADP, Adenosine Diphosphate).

We wanted to see it happen! What we did was use syringes to create a vacuum that forced the gases out of spinach leaves. This made them sink instead of float like they normally do. We then put them in a solution of baking soda and water and used lamps as a source of light energy, like the sun. The baking soda provides carbon dioxide. Plants need light energy, carbon dioxide, and water to make glucose (food). As plants do photosynthesis, they bring carbon dioxide gas into their cells and they release oxygen gas. This gas production makes them float again. So as they move from sinking to floating, you can literally watch them do photosynthesis!
This is the source of carbon dioxide needed for the plant to carry out photosynthesis. Class discussion will connect the lab to world issues; food availability, global climate ng notes and tips.
Joseph's Biology Blog: Photosynthesis Virtual Labs
The other kind of online labs are virtual labs. They enable the students to simulate real equipment and experiments. Virtual labs include, for instance, simulating collisions of galaxies to make it possible to compare them to students’ predictions that are made in advance for the experiment; simulating the whole process of a particle accelerator like the Large Hadron Collider used at ; and , the virtual buoyancy laboratory, in which students can learn in a virtual way about Archimedes’ Principle simulating the same experiment as conducted with the remote Aquarium lab described above.

Algae are a very diverse group of predominantly aquatic photosynthetic organisms that account for almost 50% of the photosynthesis that takes place on Earth. Algae have a wide range of antenna pigments to harvest light energy for photosynthesis giving different types of algae their characteristic colour. Early work done with algae contributed much to what is presently known about the carbon dioxide fixation pathway and the light harvesting reactions. The processes of photosynthesis in algae and higher plants are very similar. From among the three types of carbon dioxide‐concentrating mechanisms known in photosynthetic organisms, two types are found in different types of algae. Algae are proposed to play a role in the global carbon cycle by helping remove excess carbon dioxide from the environment. Recently, algae are recognized as a promising biodiesel source due to its efficient absorption and conversion of solar energy into chemical energy.

The lab could be used in a unit on, the scientific method, a photosynthetic unit or in a unit on environmental problems (global climate change and its affect on plants). Hystrix had lower optimum temperatures for photosynthesis compared with warm-adapted al regulation of the internal co2 concentration is well known for determining the temperature response of photosynthesis55,56,57.
