Cell - The Basic Unit of Life -- Blog 4
Everything that is alive starts with a single cell. Cells have a life cycle - they grow (G1), they synthesize and dublicate its chromosomos (S), continue growing and getS ready for division (G2), and finally enterS mitosis (cell division). Visite the following link and play the THE CONTROL OF THE CELL CYCLE GAME. As you play the game take notes and summarize each mayor cell activity that is happening. Write a 3 paragraph summary. Be sure to answer the following in your summary: Analyze the life cycle of cells, explain cellular division, and the cell event that can cause a tumor (cancer). Important: Take notes while you play the cell cycle game and use these notes to help you write your comment. PLEASE CHECK YOUR SPELLING.

Anaphase: Here we go! The separation begins. Half of the chromosomes are pulled to one side of the cell; half go the other way. When the chromosomes get to the side of the cell, it's time to move on to cellophane.
ReplyDeleteTelophase: Now the division is finishing up. This is the time when the cell membrane closes in and splits the cell into two pieces. You have two separate cells each with half of the original DNA.
Interphase: This is the normal state of a cell. We suppose that when it comes to cell division, you could call this the resting state. It's just going about its daily business of surviving and making sure it has all of the nutrients and energy it needs. It is also getting ready for another division that will happen one day. It is duplicating its nucleic acids, so when it's time for pro phase again, all the pieces are there.
I like how you put the word and wrote about it. Never forget, it is important to learn things now, and think ahead, so you won't fall behind in high school or college. It sounds like they're far away but they're right next door. Keep up the great work.

ReplyDeleteI don't understand the game. It hard
ReplyDeleteI PASSED THE GAME--only after about 5 tries. HARD, very hard. In fact, I was scared that something might happen to my cells, but I read that it is very rare for that to happen. I'm very interested in this, but we need to take it a step-by-step so I won't get confused with the chromosomes and G2 and stuff like that. When I saw the clip of the separation, my body was shaking of how nasty that looks. Good thing it is very microscopic in our bodies so I won't have to see the disguistingness.
ReplyDeleteOk Zoule, good vocabulary and no source-Ok, I see. Watch how I get you back with my eukaryotic cells and gametes and amoeba. 3. . .2. . . .1. . .Test me.
A cell division is by which a process of a parent cell divides into two or more daughter cells. Though, there are two types of cell divisions: a vegetative division, where each daughter cell is IDENTICAL to the parent cell (so called MITOSIS). The second is called a reductive cell division, where the number of chromosomes in the daughter cell are reduced by half to produce haploid GAMETES (renamed MEIOSIS). Meiosis comes when four HAPLOID daughter cells undergo in one round of DNA replication followed by two divisions: HOMOLOGOUS CHROMOSOMES are separated on their way in the first division, and on the second are sister CHROMATIDS. Both of these division cycles follow in sexually reproducing organisms at some point in their cell life. And both division processes are to be believed to be present in the last EUKARYOTIC common ancestor.
PROKARYOTES also go after a vegetative cell division so called, BINARY FISSION. This is where their generic material is segregated equally into two daughter cells. For simple unicellular organisms such as AMOEBA, one is equal to reproduction. In which an entire new organism is created. OK OK I WONT GO ANY FAR BECAUSE I"M NOT EVEN UNDERSTANDING, ok maybe 80%. On the bottom is definitions for the CAPS LOCKED WORDS.
Definitions and source:
Source: Wiki
Definitions:
MITOSIS: a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.
GAMETES: a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
MEIOSIS: a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell.
HAPLOID: having a single set of unpaired chromosomes.
HOMOLOGOUS CHROMOSOMES: two chromosomes that are identical in appearance and pair during meiosis.
CHROMATIDS: each of the two threadlike strands into which a chromosome divides longitudinally during cell division.
EUKARYOTIC: having cells with `good' or membrane-bound nuclei.
PROKARYOTES: a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles.
BINARY FISSION: fission is the subdivision of a cell into two or more parts and the regeneration of those parts into separate cells. Binary fission produces two separate cells, populations, species, etc.
AMOEBA: a single-celled animal that catches food and moves about by extending fingerlike projections of protoplasm. Amebas are either free-living in damp environments or parasitic.
ZOULE, CHALLENGE THAT.
I like your post Abdul. It includes everything that Mr.Rosado asked and more. The only problem I have is that you used a source that wasn't the game. I recommend just using the game as a source instead of using wiki. The wiki itself is extremely not accurate as people can change whatever they want. In addition, the game you played earlier was more accurate than the wiki itself so might as well use that. Other than that, your post was awesome. Keep it up man!

The life cycle of cells is pretty amazing. It all starts with one cell, and that cell needs do many things before it starts dividing. What I found interesting about this is that even though hundreds of cells are dividing at once, the cells that divide grow too. This makes the cell cycle faster. In addition, think about all the cells doing this, instead they do it multiple times in a day.
ReplyDeleteAt the last stage of the cell cycle is the cell division. What happens here is unique. Since different cells divide differently, this opens up a whole world of variety when it comes to cell division. What basically happens is that it under goes a stage called chromosome separation. It's when the cell dividing literally divides itself in half and recovers from it quickly, being able to do it again. What I find interesting about this is that I wonder how cells are able to do this on a daily basis and not get tired and or die from doing this too much.
Now in the cell division, every cell needs to have the same amount of protein. If one cell gets too much, it won't be able to progress like the other cells. This would make it a stand alone cell. Since no other cells have the same protein as that cell in the vicinity, the cell gets infected from not being used to the place it's in because it ended up being so different from the others for such a long time.Then that cell has it's own cell division process, infecting other cells in the process of it's own cell division. This ends up becoming a cancerous cell, and if smaller just the common cold.
I don't really have any sources except the Cell Division Game itself, so I'll just put the link to that.

Thanks Brian for the reply, it really helped. I loved it and maybe I'll use what you said. After all, you hooked me up with "The life cycle of cells is pretty amazing". To admit, your was more easier to read than mine. Good Job and keep your brain healthy with math and science.
ReplyDeletei finished the game yay!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! i was mad because i didint get some right but then i kept going and got some right. :) xd
ReplyDeleteI finish the game!! yea !! The first time I played it, I was angry because i'll get the questions wrong and try again. But, on my second try I finish it at last!
ReplyDeleteDefinitions:
Lysosome: are the cells waste disposal system
Mitosis: is the process by which a cell, previously replicated each of its chromosomes
homologous chromosome: set of one material chromosome and paternal chromosome that is pair up with each other in the cell during meiosis
Meiosis: is a type of cell division for sexual reproduction in eukaryotes
Eukaryotes: is in any organism that contains a nucleus and other structures
I wasn't able to finish the game but I'm going to try to respond to the blog to the best of my ablity. I understand that the first part of the game explained that different cells die at different rates. Some very often and others once in a life time. The other part wanted me to answer questions. Like what's happens after a cell dies?
ReplyDeleteAfter a cell die the one near it takes its left overs so it can grow. The cell's membrane checks to see if the cell is good enough to grow. It checks the insides first. Then the outside later. After the cell grows it duplicates to fill the spot the old cell left. Like the check it duplicates the inside first and then the outside.
The game was exstrodinary is was very cool. The game was very difficult... Well at first then I understood the consept of the game. I was amazed what they could do. This game isn't for everyone. OK so if I was todiscribe this in a summary I would say this is an educational game. This is a game that trains you and your understanding of science.
ReplyDeleteIt was a great game. The cells and how it happens is facinating. It is so cool how they multiply. I did a little reaseaerch on cells and they multiply to stick together to make things like soil. It also makes the things inside your body. The cell are what some say the building blocks of life. It is
In conclusion the game was for intelegent people. It also teaches. Itid educational. Its fun. Its interesting for those wh choose it to be. The game made me look at science in a different way. In connection to my first. Hi Mr rosodo
ReplyDeleteGreat work guys!
