- they are alive! Bacteria are the most simple beings who are alive. Bacteria are everywhere. They are in the food you eat, soil, plants grow in, and even inside you. They are very simple cells that fall under the heading prokaryotes. This word means that they have no organized nucleus. Bacteria are small single cells, the whole goal in life is to copy. Good. So, we told you that they have no organized nucleus. True. They have DNA. He grouped in the area called the nucleoid.
They have a cell membrane, like other cells and even protective cell wall. Keep in mind that their cell wall is similar to the one in the plant. This special type of bacteria for protection. They do not have organelles, just
ribosomes. (All these characteristics of prokaryotes, if you remember).
They look? Very strattera cost little. Very, very little. You've probably seen pictures of some bacteria. Since we do not know what you saw, we will tell you there are three main forms. Spherical bacteria in the form of small balls or bullets. Typically, they form chains of cells, as well as a number of circles. Rod shape bacteria look like Escherichia coli
live in your intestines. Can you imagine a bunch of bacteria that look like hot dogs. They can make the network as a set of connected sausage. Spiral bacteria form little twist. Think about the balloon animals for these forms. It's like a balloon animal in the form of spin. What are they doing? Anything. Sorry, so sad, but almost everything. Some help plants absorb nitrogen (N) of soil. Some of them cause diseases such as botulism. Some bacteria even live in the stomachs of cows to help them break down cellulose. Cows can digest their own grass and plants, as well as we. They do not get many nutrients from plants and can not break
cellulose. Since super bacteria, cellulose can be broken down into sugar and then release all the energy they need. Imagine if scientists could develop bacteria live inside us, that would break the plants. That would be something. We could eat grass and leaves throughout the day. .
