Did you ever hear of a swimming plant before ? There are also other lifeforms in the drop of water. Some single celled Protophyta can swim too. There are also single celled plants called protophyta in the drop of water and they photosynthesise sugar from sunlight for energy, just like trees and plants do. You might just be able to see this little water flea. There are other creatures which are multi-cellular but still so small you could hardly see them at all with the naked eye. They are some of my favourites to watch as they have lots of energy and often bump into each other. This enables them to move in any direction.
There are different types of single celled creatures including amoeba which look a bit like moving jelly and a big group of Protzoa called the Ciliates and they are covered in tiny little undulating hair like structures. That's quite amazing if you think about how many different bits of you there are. They can make do with all the functions of life they need and exist as just one cell. We humans are made of trillions of cells, that's a 1 with 12 zeros after it (1,000,000,000,000) and even tiny insects are made of billions of cells, but Protozoans are a whole creature in just one cell. They are single celled animals, which is a fascinating fact to think about. We now call the tiny creatures in a drop of pond water Protozoa or the rather magnificent title The Protozoans. For the first time we could see the difference between plants and animals at the cellular level. We could also look at other animals and plants in minute detail. We could look closely at the cells within our own bodies and work out how they functioned. It made him very famous and people began to copy his invention.īefore very long, more powerful microscopes were built and as they did, people saw more and more details emerge and we began to understand the microscopic world. He made drawings of them and people were amazed when they saw them for the first time. He saw the tiny creatures for the first time and studied them. Until a few hundred years ago, people had never even seen them before and it wasn't until a very clever scientist called Anton van Leeuwenhoek invented the first real microscope that they could. But inside this drop of water is a tiny world of creatures so small that they are invisible to the naked eye.
If you take one drop of water from a pond, you can't usually see anything at all.
