Cell structure and diversity

nerve by estherase on flickr

Take some time to click through this site to learn more about cells and their structures.   Here is another good place to learn about cells.   Look through each site and then leave me a comment as to which of them you preferred and WHY

If you find any other sites on this topic that you think would help your classmates learn, please include them in the comments too.

Here is a link to a quiz that you can use to check your understanding of cells.  It is brief – my advice is that you study the structure of prokaryotic and eukaryotic cells, and their functions, and their differences, then see how you go on the quiz.  The answers are on there too, so you can self-assess.

Quiz – cell parts and their functions

What do all cells have in common?

Why do cells differentiate?  Within the same organism, there are differences between cells – why is this?

Here’s what you need to do:-

  1. In your groups, make a list of all the different types of cells you can think of (eg, red blood cell, leaf cell)
  2. Each student chooses ONE cell type to research.  Draw the basic structure, state its function, describe why it is unique, and where it is found.
  3. Share your findings with your group.
  4. Discuss the similarities and differences between the cells you described.  Are cells more alike or more different from one another?  Are some cells more complex than others?  Which ones? 
  5. Try to explain why cells have these similarities and differences.

    I dont mind either one of the sites. they both help. they both have positive points both work in helping me understand.

  2. Asha says:

    I think that the http://www.biology4kids.com/files/cell_main.html is the best website out of the two, as there are no ‘blocks’ of writing, it has good information, and good pictures. Also, the other site is a little ‘kiddie’. Therefore, that site is more useful as it explains everything vey well.

  3. Kate C says:

    I prefer thinkquest.org since it provides several links and detailed explanations. It’s more helpful for adolescents and adults. The other website biology4kids.com is more for kids and has brief explanations. It’s not as informative as the first site I mentioned.

  4. I prefered the biology for kids website better than the other website. The biology4kids website was better than the other because of the easy way to follow along with the information and is not just a full page of just words that can lose my attention and the data is more simple to understand. Also the excell cells looks like there was little effort in design and rushed the project.

    I believe that both sites are equally resourceful.

    The first site, Biology4Kids.com I think was thorough in explaining the different organelles in the cell and the different functions of the cell. On the other hand, the second site “Excell At Cells’ focused more on the actual structures of the cells (using diagrams) and the different individual cells, such as animal and plant cells.

  6. Adilet says:

    I prefer the first site because it contains more information.

  7. Charlotte says:

    I like this site the best: http://library.thinkquest.org/5420/index.htm

    This is because it covers different subtopics of cells and easy to find information. It is concise and clearly understandable. However, the information is in large chunks and unappealing to read. The first site is a little broad and only covers an introduction to the topic, not going into much detail

  8. Joy says:

    I think that the the second website is better, “ExCELL” for Cells. That is because I felt that this website focused on different cells and its components. Furthermore, it elaborated on the job of each components depending on the type of cell.

  9. Varun says:

    I prefer site A because there are more diagrams and they are more explanatory

  10. Amy says:

    I prefer the second site. Because it is entertaining to read and it have a lot of information. It have more pictures and some of them are animated, showing how cell is divided, so it give me a better understanding on how the cell moves and divide themselves.

    But I kinda doubt if the information is trustworthy or not since the ‘about the author’ page stated that it was created by 3 kids from a club.

  11. Kelvin says:

    I would prefer the “Excell at cells” website because it has a bit more info about animal and plant cells, and it gives abit more info about DNA viruses.

    Hi Mrs. Dickinson,

    I looked at both sites and read through them. It was very difficult to choose which one I prefer as they both have excellent information. When I first went to both sites I thought Biology4Kids.com would be better than “Excell At Cells” because it looked more professional and had better drawings. However after giving them a good look, I realized that I prefer “Excell At Cells”. I feel that it gives clearer and deeper explenations, but still in a simply way. I also like the way it includes links to show you different parts of it’s website. Another fun part is inbetween paragraphs they place trivia about the cells. Althought the pictures aren’t as nice, they still are properly labeled. So I feel it is a better choice for research. 🙂

  13. naoto says:

    I prefer “Excell At Cells” better because it talks about the variety of cells and thats what we need for this research.

  14. SrinivasanK says:

    I preferred site ‘Excell at Cells’ site over the ‘Biology4Kids’ site as the language used in that site was beter and more “scientific” in terms of the language used. For example, ‘Biology4Kids’ site described cells as “pieces” and animal cells as “animal-like”, which I feel is too kiddish for a 9th grader. Apart from that, even the diagrams are considerably more detailed in the site than in Biology4Kids site. All in all, i prefer Excell at Cells as it has more appropriate language for a 9th grader.

  15. Wei Hao says:

    The website I prefer is Biology4Kids.com because it presents a a more simpler explanation of cells. It is more clear and easy to understand and I like the diagrams more than the other site. This information would be more useful to me in this task.

  16. soj says:

    http://www.biology4kids.com/

    it think this one’s better beacause it has recognitions from organizations and the other site was made by kids who aren’t thebest reliable source…

  17. Hank says:

    I preferred Biology4Kids.com. This is because Biology4kids goes into more detail, is more organised and is cleaner. Also, Biology4kids gets to the point faster and does not get side tracked.

  18. Cc says:

    I believe that the first site given was better because the individual overview’s descriptions of the cell parts were very informative

  19. If says:

    I thought that Biology4kids was a better site. It explains in great detail and has links to a lot of relevant information. Also, the diagrams are better in Biology4kids. One great advantage is that all the links are their on one page and you can navigate to whichever you want with ease. In excell you have to click on a sub-topic than go back to the main page.

  20. Santiago says:

    I prefer biology4kids.com because it is detailed and simple to understand. The diagrams however, are quite unclear and seem broad. The other website is too simple and the diagrams at all are not clear or helpful.

  21. Harry g says:

    I liked the Biology for kids site because it was much simpler and much more straight forward. I didn’t have to navigate through multiple pages for tidbits of information.

  22. Stuart says:

    I preferred the second website because it had pictures and was more colorful so the links were easier to find while in the first website all the links were on the side so they were hard to find.

  23. Daniel T says:

    I think BIology for Kids is best, because it is the easiest to read and navigate

  24. A.W says:

    I prefer the second page because i like how it is divided into different topics and it has very interesting information, it is easier to navigate in it and also there are many fun activities you can do to learn more about cells.

  25. SweeK says:

    I prefer “Excell at cells” because it consists of more information about cells and it is organized in a way that it’s easy to navigate the information you need.

  26. Bettina says:

    I think Excell at Cells is the better website because it has more information but it is easy to understand the language. Also the website is organized so it’s easy to find what you need.

  27. ChingN says:

    When comparing both websites, I preferred “Excell At Cells” because of the quantity of information given. Compared to Biology4kids, the diagrams were labeled. Every tab in the first website did not show any labels whatsoever.

  28. Annika says:

    I think this http://library.thinkquest.org/5420/index.htm site was better. I described the cells and things concerning them better and more simple. At least I understood better.

  29. Panchalee Perera says:

    I think that both sites are good sources of information about cell but I Prefer this site
    http://library.thinkquest.org/5420/index.htm
    This site is very organized, easy to understand and the topics are well divided. It is easy to find information about certain types of cells. It is also very user friendly.

  30. Husan says:

    I think the Excell at cells is a better site to learn about cells because it has more information and many more categories.

  31. Ramya says:

    I preferred the second site, “Excell At Cells” because the formating of the site is user friendly and it is easier to search for information on a specific topic about cells. The site also has interactive activities like a quiz and crossward puzzles. Overall, I like the information on the site and how the site is layed out or formatted.

  32. Disha says:

    I prefer the excel site http://library.thinkquest.org/5420/index.htm because it has much more information and it is written in a better way. It explains things much more better than the other site.

  33. Yusuke says:

    I prefer Biology4Kids.com more because the language they use is simple, and easy to understand just like my science class. The images are like hand drawn, and easy to figure out the organells. The key words are bold, so its easy to skim through the page and memorize the important points. The hard words such as “mitochondria” are hyper-linked to more detail.

  34. Jamie says:

    I find both websites extremely helpful information wise and age appropriate. Although, I much prefer the second site, “Excell At Cells” because I like the way it is structured and organized by the different types of cells making it more user friendly. Also, the site itself contains general and specific information on cells.

  35. Arshaan says:

    I think the “excell at cells” website is better because its easy to navigate and the level of information is exactly the level for me.

  36. Cathalina says:

    Hello Mrs. Dickensen the web site that I preferred is Biology for kids. Althought both are reliable “Biology for kids” has the same information as “Excell at cell” and has extra information on the subject. although the information in “Excell” is correct and exact, the authors are elementary kids. Both websites have helpful pictures and activities. What I like mostly about Biology for kids is that they have further information about each organelle, its functions and other cells that are unicellular.
