Can you help me understand this basic of biology?

Question

Can you help me understand basic biology?

where is cell inside the body? What is it on the top of the cell?

What is inside the cell, and what are those things? What those things do? What is organ structure?

What is DNA and RNA? What is these made of? What are their functions? How many DNA are there inside each nucleus? Why they called "sugar" for DNA or something? What they meant by "sugar"?

What is atom? How are they made up? Where is it in my body?

Where are the bacteria inside my body? Where they live in the body? Is it genetic or I get it from somewhere else?

Please answer question as you are answering to 10 years old, because I have never thinking of these things. Now, I feel like I should major in Biology because I am curios to know. I have never taken Biology class, before. Do not use much hard word that I will not understand. Thank you. I feel like I am interested in these topic, so If you know something more about Biology then please let me know. Thank you so much.

Answer 1

You are asking too many questions for me to give a good answer here.  I suggest that you start with wikipedia and look for cells to start, the articles are actually very good.

Answer 2

simple answer to your question..go to your library and check out a biology  book and read it..or google it

Answer 3

An intro bio textbook would help. Perhaps you could look in the "science" section of the kids' nonfiction section of the library; there are good books that answer your questions with pictures, very clearly.

But I'll try and answer some now too :)

Your entire body is made of cells. Each of your organs - your heart, lungs, intestine, liver, skin, eyes - are all made of cells. However, cells aren't all the same. There are many different types, and that is why your eye is different from your skin.

Cells make up your blood vessels, which take blood where it is needed in the body. They also make up your stomach and intestinal tract, so that your body can absorb energy from food. Your lungs are made of cells, and there they take oxygen from the air and put it in the blood, so that your blood can transport it to other cells that need oxygen.

Your body needs oxygen to use food to make energy, and you need energy to live!

Inside the cell are many parts. If you google "cell parts" or "cell diagram" you'll have a lot of good pictures.

I'll mention a few parts now.

The "nucleus" is the brain of the cell. That is where DNA is, and DNA tells the cell what to do and what to make.

The liquid filling the cell is called the "cytoplasm".

The outside part of the cell is called the "plasma membrane". It lets some things into the cell while keeping others out.

The powerhouse of the cell is the "mitochondria". It makes energy from food. This energy lets the cell make other things that your body needs, and also lets your muscles contract, and keeps you warm.

The factories of the cell are called "ribosomes". They use RNA (which is copied from DNA) to make proteins, which are used everywhere in your body for many things.

DNA is in the nucleus. It is tightly coiled, but uncoils when the cell needs to make something. DNA is double stranded. RNA is made by copying a strand of DNA, and then it leaves the nucleus to enter the rest of the cell.

There, it's used as a template by the ribosomes to make proteins.

Proteins are used to do almost everything that needs to be done in your body. They transport things, they connect things, and they hold up your body.

DNA has a sugar-phosphate backbone. It uses a type of sugar (deoxyribose) and a phosphate (another compound) to make a very strong chain. That is what lets it coil, and keeps it stable.

Atoms are the smallest division of matter, for the most part. They are made up of electrons, neutrons and protons. Atoms joined together make compounds (like the deoxyribose sugar, or the phosphate) and the compounds join together to make even bigger molecules (like the sugar-phosphate backbone).

Bacteria live in most of your body, but especially in your mouth and in your digestive tract. The ones in your digestive tract are necessary for you to properly digest food. They are not genetic, since they are not part of your body, but they are in some foods, and that is how you get them.
