I can eat a kohlrabi, but what does it eat?

Courtesy of Wikipedia commons - A simplification of the photosynthesis processKohlrabi is autotrophic, meaning self feeding. This indicates that its main source of food will be glucose molecules that are made through the photosynthesis process. Photosynthesis follows the general equation: 6CO2 + 6H2O (+ light energy) + 6O2. This means that for a plant to make its own glucose molecules it needs 6 molecules of CO2 and 6 molecules of H20 in addition to light energy to provide a boost of energy for the process.  Kohlrabi is a tough vegetable. Being originally from Northern Europe means that this vegetable can withstand low temperatures. In modern times, Kohlrabi can be grown just about anywhere.Courtesy of Wikipedia Commons - A picture of Xylem and Phloem For more information on Photosynthesis, check out this site.

Kohlrabi is a vascular plant, meaning it has a system of tube like structures that transport both water and food throughout the plant. These "tubes" are called xylem and phloem. Xylem is used to transport water and dissolved minerals up while Phloem transports sugars throughout the plant. Kohlrabi would not have a circulatory system but instead would rely on Stomata, which are small openings in the leaves that can be opened or closed, for gas exchange.

In this picture, Xylem is 3 and Phloem is 4

This organism does serve as food for other organisms such as people. That will be explained in the next section but what about other organisms? Kohlrabi does have several organisms that eat it or have it as a host. For the general overview on this, check out the Interactions section.
So that is how a Kohlrabi eats but what about when a person eats it? Go to Nutrition Facts to find out or you can always head back to the main menu.
