bacteria were discovered by a dutch merchant named Anton von Leeuwenhoek. Anton’s hobby was making microscopes, while looking at scrapings of his teeth, he noticed small wormlike organism ( bacteria).

Bacteria are prokaryotes. The genetic material in their cells is not contained in a nucleus. In addition to lacking a nucleus, the cells of bacteria also lack many other structures.

Structures in a typical bacterial cell 👇🏻

The cell wall protects the cell. Inside the cell wall is the cell membrane ,which controls what materials pass in and out of the cell. The region inside the cell membrane is the cytoplasm, that contains a gel-like fluid that moves structures throughout the cell. Located in the cytoplasm are tiny structures ( ribosomes ), chemical factories where proteins are produced. A bacterial cell may also have a flagellum, a long whiplike structure that helps a cell 🦠to move. If a bacterial cell lacks the flagellum it can be carried from place to place by air, water or even organisms !!

cell shapes:

If you want to know how a bacterial cell looks like just look 👀 to their following shapes , there are three basic shapes: spiral,spherical, or rodlike.

cell sizes:

Bacteria vary greatly in size. The largest known bacterium is about as big as the period at the end of this sentence. For example, the spherical strep throat bacteria 🧫 is about 0.5 to 1 micrometer in diameter. A micrometer is one millionth of a meter!!

Bacteria get energy by either making food 🥘 or eating other organisms, and can reproduce asexually or sexually.

Do you know that when the bacteria 🦠 have plenty of food, the right temperature, and other suitable conditions, they thrive and reproduce often either asexually or sexually!! And did you know that many of the bacteria living in your body actually keep you healthy? For example your intestines teem with bacteria. Some help you digest your food. Some make vitamins that your body needs! Others compete for space with disease-causing organisms. They prevent the bacteria from attaching to your intestines and making you sick 🤒.

Scientists 🥼 use certain bacteria to make medicines and other substances. By manipulating the bacterias genetic material, scientists 👩‍🔬 can cause bacteria to produce human insulin. Although healthy people can make their own insulin, those with some types of diabetes cannot. Many people with diabetes need to take insulin daily! Thanks to bacterias fast rate of reproduction, large numbers of insulin-making bacteria can be grown in huge vats . The human insulin they produce is then purified and made into medicine. So, thanks bacteria 🦠🙏🏻

This is an example post, originally published as part of Blogging University. Enroll in one of our ten programs, and start your blog right.

You’re going to publish a post today. Don’t worry about how your blog looks. Don’t worry if you haven’t given it a name yet, or you’re feeling overwhelmed. Just click the “New Post” button, and tell us why you’re here.

Why do this?

• Because it gives new readers context. What are you about? Why should they read your blog?
• Because it will help you focus you own ideas about your blog and what you’d like to do with it.

The post can be short or long, a personal intro to your life or a bloggy mission statement, a manifesto for the future or a simple outline of your the types of things you hope to publish.

To help you get started, here are a few questions:

• Why are you blogging publicly, rather than keeping a personal journal?
• What topics do you think you’ll write about?
• Who would you love to connect with via your blog?
• If you blog successfully throughout the next year, what would you hope to have accomplished?

You’re not locked into any of this; one of the wonderful things about blogs is how they constantly evolve as we learn, grow, and interact with one another — but it’s good to know where and why you started, and articulating your goals may just give you a few other post ideas.

Can’t think how to get started? Just write the first thing that pops into your head. Anne Lamott, author of a book on writing we love, says that you need to give yourself permission to write a “crappy first draft”. Anne makes a great point — just start writing, and worry about editing it later.

When you’re ready to publish, give your post three to five tags that describe your blog’s focus — writing, photography, fiction, parenting, food, cars, movies, sports, whatever. These tags will help others who care about your topics find you in the Reader. Make sure one of the tags is “zerotohero,” so other new bloggers can find you, too.
