If you’re like millions of other people, you may experience some uncomfortable allergy symptoms several times during the year. One of the major allergens that cause these symptoms is pollen. Sometimes, you can see pollen floating through the air in large patches, but not always.
The best way to see pollen in detail is to look at it under a microscope. Unfortunately, most people don’t just have a microscope sitting on a shelf! In this article, we’ll look at what exactly pollen is and how you can expect it to look under a microscope. We’ll also review what you need and how you can look at pollen yourself.
Simply put, pollen is a substance that comes from seed plants and assists in reproduction. The male gametes (sperm cells) are produced by the pollen. When these gametes land on compatible female cones or pistils, germination results.
Clumps of pollen are visible to the naked eye. However, to see any details of the individual pollen grains, one would need to look at it under a microscope or otherwise magnify the size of it.
There is no single way that pollen looks because it actually varies in shape, size, and color between various species. Some common characteristics you’ll notice under a microscope could be the pollen from pines, spruce, or fir having wings, or the pollen grains from a forget-me-not being only 2.5–5 micrometers in diameter.
The answer to why we experience allergies when there’s pollen in the air can be found within our immune systems. The job of this system in our bodies is to fight off any foreign intruders, harmful viruses or bacteria, for example.
When pollen causes an allergic reaction, it’s because your immune system mistakes the pollen for a threat to the body. In response to the “threat,” your body begins creating histamine, a chemical that fights the pollen. This is why many allergy medicines contain antihistamine medication.
Since there are many different pollen grains with unique looks, it’ll be more useful to know what you need to see them under a microscope.
For this article, we’ll discuss techniques specific to a stereo microscope because it’s one of the most commonly used microscopes.
Before viewing the pollen under the microscope, it’s a good idea to treat some and view it alongside an untreated specimen. This enables you to easily compare differences.
This is only one method of viewing pollen under a microscope. For example, each microscope—compound or electron—will have a slightly different operation. To view pollen under any other microscope, simply follow the typical viewing procedure for the particular microscope you’re using.
Pollen is a fascinating part of nature. If you’re exploring it with a microscope, make sure you look at several varieties so you can see how diverse and unique pollen structures are between species.
