Answers:Use foam and colored glue and toothpicks or pins to label things so they can come out and go back in. i have to do the same project except with an animal cell or a plant cell. good luck and i hope you get an A!
Answers:use play dough or flour. You can get them from staples or an art store. Differenciate the membrane, cytoplasm and nucles with different colors.Those are important. . It's best to mold the cell with a ventral view in mind. so that the organelles can be seen from the top and the external features seen from the top and by lifting it up.
Answers:The muscle cell would be the easiest to construct.... depending upon how particular the model has to be. To score a high mark, I would suggest making a model of the cell when it is relaxed and when it is contracted. I would suggest getting the book Gray's Anatomy. While it is a book primarily focused on the surgical anatomy of the human body, the first chapter has an in depth explanation of plant and animal cells. For 3-D construction, I would suggest using 3-D rendering software. This way you could have an exact model with a relatively easy creation process (in addition, there would be no cost if you downloaded Google SketchUp). With this, you could also, potentially repeat the cell to show an entire muscle, and with a little extra work, have an animation that zooms to a particular cell... feel free to e-mail me if you need any help. If you want to do a 2-D model, I would also suggest using the computer, to eliminate human error.
Answers:DNA - is the genetic code which ensures that daughter cells inherit the same characteristics as the parent cells, it is the code from which all protein is synthesized. Cytoplasm - The cytoplasm plays a mechanical role, eg: to maintain the shape, the consistency of the cell and to provide suspension to the organelles. Nucleus - The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. The nucleus provides a site for genetic transcription that is segregated from the location of translation in the cytoplasm. cell membrane - The cell membrane surrounds the protoplasm of a cell and in animal cells physically separates the intracellular components from the extracellular environment. Fungi, bacteria and plants also have the cell wall which provides a mechanical support for the cell and precludes passage of the larger molecules. The cell membrane also plays a role in anchoring the cytoskeleton to provide shape to the cell, and in attaching to the extracellular matrix and other cells to help group cells together to form tissues. The barrier is differentially permeable and able to regulate what enters and exits the cell, thus facilitating the transport of materials needed for survival. as for the nerve cells that is allot of info your asking for so I suggest that you look it up your self text books are best but here are some links that should help. http://www.google.de/imgres?imgurl=http://www.naturalhealthschool.com/img/nervecell.gif&imgrefurl=http://www.naturalhealthschool.com/9_2.html&h=354&w=400&sz=10&tbnid=2Kyol9XJCQ-t_M:&tbnh=110&tbnw=124&prev=/images%3Fq%3Dnerve%2Bcells&zoom=1&q=nerve+cells&hl=de&usg=__Hf6EFzSlp1CJj68JKU6BZ0D0zIY=&sa=X&ei=wyTwTKzfIIHssgbXxOT3Cg&ved=0CCgQ9QEwAg http://hyperphysics.phy-astr.gsu.edu/hbase/biology/nervecell.html hope this helps
