cell model

[nikcola]

come on all you arty people

i need to make a model of a cell (well 2 models one bacterial and one animal ???) any ideas as what i could do im racking my brains i was thinking as using jelly for the nucleus(sP) but cant think of anything else

p.s it doesnt have to be food btw!!!

how big does it need to be?

i doesnt say anything about size but the ones from last year where no bigger than shoe box size

Plasticine?

Coat hangers bent into different shape and paper machee (I'm sorry I have no idea how to spell machee -!?!)- maybe lumps of plasticine to be the electrons and protons ??

im just looking at my physiology work..... yes use jelly as the nucleus, brown smarties for ribosomes, ribbon for smooth endoplasmic reticulum and mohair wool for rough ER. um... cooked spaghetti pasta shaped to look like a golgi apparatus? how does that sound?

sounds good then i can eat it !!!!!! ill let you no how i get on any ideas about the aniaml one

Plant cell:

grey plasticene ball (or blu tak or similar) for the nucleus.

Put this in a see through plastic food bag (wich will be the membrane), add wall paper paste, jelly, gelatine or something similar for the cytoplasm.

pop a smaller bag of water done up tightly in with the jelly etc for the vacuole, and some green bits of plasticene for the chloroplasts.

Put the whole thing into a food box or luch box or margarine tub for the cell wall.

Oops you said animal and bacteria. Well, for the animal, you just need the nucleus, cytoplasm and and membrane as described as well.

Bacteria have a nucleus, cytoplasm, membrane and a cell wall, I think.

HTH.

Right,

The animal cell (eukaryotic)

Get a large clear platic bag and fill with wallpaper paste. Use a black ping pong ball for the nucleus, use smaller balls for mitochondria, glitter for the chemical reactions taking place in the cytoplasm.

The bacterial cell, same deal re plastic bag and paste, black wool for the main mass of the dns (no nucleus), you can have small pasmids of loops of wool. Put the lot in a carboard box (cell wall) which can have flaggela made of pipe cleaners.

Do you need to go into detail og golgi etc is it for collage or kids, if the latter, what age?

Ooh yes, hmb. Shame on me... my bacteria attempt was rubbish!

brilliant ideas no we dont have to go into that much detail

i hope

You could be very cool and try to get the relative scale right....that would impress. make the animal cell 1000 x bigger! It is the one thing that the kids never seem to 'get'. The box is important as it does make the cell wall explicit. I would also steer away from an 'on a plate' model as it is the 3d-ness (IYSWIM) that these models helps to get over

Aw hmb - I was just going to say you've all forgotten the mitochondria but you remembered!!

Great idea by the way!!

has anyone got a pic of the two cells eukaryotic and the other one ermmm the one that begins with p my minds gone blank

prokaryotic (without Nucleus)

have a look at

A lot I know but woth the cut and paste

very helpfull thank you xxxxxxxxxxxx

im so stuck with this is driving me nutts my biology book is rubish,

does the prokaryotic cell not have a cell wall too

and witch is the animal cell and witch is the bacterila cell and is the animal same as a human cell m having a bad day

its for biology for my next assignmnet due in next tuesday im really struggling with it i have to make a eukaryotic and a prokaryotic cell and write a hand book with eacj cell to explain all about the organells and loads of other stuff too but i just cant get my head round it

Sorry we x posted.

A Eukaryoteic cell is anything with a nucleus. there are two main types animal cells and plant cells. Human cells are animal eukaryotic cells. Animal cells have, Plasma membrane, Rough and smooth ER, golgi apparatus, mitochondria, small vesicles (which may be full of enzymes), a nuclear membrane with DNA withing which will also have a nucleolus (or darker bit), they also have centrioles (involved in cell division). Plant cells have all the above except centrioles. Plany cells also have a cell wall, a large sap filled vacuole and chloroplasts containing chlorophyll.

Prokaryotes don't have a 'formal' nucleus, and are mostly bacteria. They are a thousant times smaller than a eukaryotic cell.

HTH.......you do realise that I have marking to do, and I'm putting it off

And that should read Peptidoglycan

Could I just butt in and tell you that my friend made me a toy chlamydomonas when we were doing A level biology?

There's a post you don't read every day on MN....

LMAO!!!!!!!!

Fab! have you still got it??????

I have, although it might take me a while to put my hands on it... She made all the organelles out of felt and stuffed them then suspended them inside the body. She even embroidered chromosomes on the nucleus. What a star

Ah, Chromosome, was it undergoing cell division then???? (having just taught this to the sixthfrom and it took about 10 minutes to get it through to them about condenstation of the DNA into chromosomes in prphase....please don't tell me that this is all a load of toffee....I know you know your genetics!)
