What is Mitosis? Mitosis is the cycles of which a cell goes through before it duplicates itself. There are two types of cells. Prokyreotic and Eycariotic. The Prokyriotic cells have no membrame bound organalles or a nucleus. They contain mostly bacteria and algae. Eycariotic cells do have membrame bound organalles and a nucleus. They are mostly plant or animal cells. The cell I am going to be talking about is the Eycariotic cell. The cell is always most of the time in Porphase. Prophase is the phase which the cell is getting ready for the duplication of the cell. The cell begins to go to metaphase, the phase which the DNA is lining up like an equater in the cell. The cell is always copying its DNA so it can give some to the new cell to which is about to be made.

     The cell later goes into anaphase. In anaphase, the cell begins to duplicate and the nucleus begins to form in the different cell.

     Bacteria? Animal cells? Plant cells?! What do they have in common? Well, they do have lots of things in common, but most of it is diferences between the cells. They are very different in fact. It all has to do with the inside of the cell. bacteria cells are the most different out of all of the cells. The have cell walls and a membrame, like plant and animal cells, though animal cells don't have cell walls. The big difference about the bacteria cell, is that it has no nucleoulus, no nucleus, and no membrame bound organelles. They do have vacuoles, but they jut flout around the cytoplasm. They also have DNA, but that also just foats around the cytoplasm.

     Next, we have an animal cell. These are very same to a plant cell in many ways, but also different in many ways. They have no cell wall. They do have a cell membrame, and membrame bound organelles. They also have many same organelles as a plant cell. Unlike the bacteria cell, they do have a nucleoulus.

     Not to long ago, we did a project with cells. It was the ediable cell project. The ediable cell was used to help us understand the parts of a cell and what they do. So was this a good project to do? I, personaly, think it was. It really helped me get the idea of wht cell parts looked like. We had to use non perishable food items. When we made this, the food items really helped me visualize what the food items do and what they might look like. We did an animal cell. This really helped me get a better understanding of what the cell parts are called and what they do in the cell.

     We had to know what each part of a celll was called, and what itt

     Parts ofa cell? Wel, I have chosen the cell membrame, the cell wall, and the nucleoulus. The cell membrame is in both animal cells and plant cells. The membrame is like a wall. The only difference is that it can control waht comes in the cell and out. The membrame has little holes in it and it also covers a cell. In an animal cell, it covers the cell. In a plant cell, it goes underneath the cell wall. Next is the cell wall. This is onjly found in a plant cell. The cell wall provides protection for the cell and it keeps all of the bad things away from inside the cell. Last, is the nucleolus. The nucleoulus is inside the nucleus. It is the brain of the cell.

     I rememberin science class, we had to do an assignment on cell parts. We got a paper with riddles and a city on the back. We ad to solve the riddles with parts of a cell, and we had to name parts of a city with cell parts.

     Baby rats are very fast growing creatures. They can become an adult in a couple of months. When a mother rat has babies, they usually have a litter of three to five. When a rat grows, the tail is ussually the longest thing in their body. When they grow, their tails get longer. We did an expeiment with baby rats. We watched them grow and develop. Thy still had tails longer than their body. They developed faster than I thought they would. I knew that they would reach full maturity.

     My favorite cience experiment has to be the one with paper frogs. That lesson was used to teach us about variables. when I say variables, I don't mean x or z in algebra, I mean the differencesin experiments. What I mean by that, is that we had a hypothesis. Our question was what paper frog could jump farther, paper or card-stock. That was the variable in the experiment. The different thing in the experiment was that one paper frog was card-stock, and the other was just plain paper.


     The way we found out which frog had a longer jump, we had them jump,

     How do you know that your cells are working even though you cannot feel it? Well, your alive, aern't you? If your cells were not working you would be dead. Your cells do all of the work inside your body. They let you breath, they keep your heart going, and they perform all of the chemical activities in your body. Lets take blood for example. In your veins, there is millions of tiny little red blood cells. The red blood cells carry oxtegyn through out your body.

     Lets go with the most basic need of life, air, or oxtegyn. We breath oxtegyn so we can live. When we breath, it's through our lungs. Our lungs have little tiny cells that keep the lungs working correctly. If the cells were to be eliminated, your lungs would not work. If your lungs didn't work, you would die. Our cells keep us alive so that we can live.

     What family traits do I posses? Well, I havent heard about me looking like my parents. I have heard that I looked like my uncle though. I do have a love for football and the sport, and I think I got that from my dad. Also, I'm very smart (I go to Computech) which is probaly from both of my parents. I don't look like my brothers at all. They are both smart, but we don't look anything alike. Pretty much all the time, when I tell people that we're related, they go like "really" or "are you sure?"I don't have a mojor athletic abiltiy, but I don't give up. Even when things get tough, I stay with my head in the game.

      How do you find the volume of an irregular object? Well, how about I tell you then. In order to find the volume of an irregular object you need to multiply lenght times width times hieght. Lets say the lenghth of an object is ten and thwe width is tw, well that would be twenty. But it's not over yet, then you multiply it by its hieght. Lets say the hiefgt is fifteen. Then the product will be250.

     What have we been learning in Science? Well,  we have mainly been learning about the metric system. In class we have been doing experiments with the metric system, such as measuring and volume. On Friday, we used ruler and measuring tapes to measure the leanghth of  different objects lie string and tables. Then, we recorded all of the data on a paper. After that we went over it to see what the right answers were. We also did an experiment with paper and card-stock frogs. The experiment was that we had to make one of each, paper and card-stock, and make them "jump" across a ruler. After that, we recorded the data and checked which frog had the highest data.

        One last experiment we did, was cubic measurment and volume. what we did is that there was five stations and each group had to go to each station once. After that, we got little cubes to esimate how much cubic meters each three dimensional item had. Then we measured leanghth, width, and hight. We got a volume from all of the data, to find the exact amount of cubic centi-meters each object had.
