that is stupid. All of the following are absolutely necessary for an eukaryotic cell: Nucleus, ribosomes, lysosome, golgi, cytoskeleton, cytosol, SER, RER, nucleolus. Without these, there can be no cell

Agreed, stupid question….

stupid teacher 😆

stupid Que 😆
Is your teacher OK?
It is like…."What are the non-essential features of house?"
1.Walls
2.Door
3.Window
4.floor
5.Roof
6.Funiture………. 😆

But then also I will answer that…

1.Nucleus……… Includes Nucleolus and centroil factor.

2.Cell wall……….Essential to maintain osmotic pressure.

3.Mitochondria……… Ofcourse; energy House.

4.RER………… Includes ER; Ribosome; part of cytoskeleton.

5.Cytosol……… All other parts are included in this.

So give this answer to your teacher….

He/She will get a Shock 😆

For a cell, everything is essential. Perhaps your teacher should rather ask what are the most well-known organelles ?

cell wall esential for maintaining osmotic pressure?

ei sachin… maybe ur referring to cytoplasm? cytosol and cytoplasm are different terms, remember… 😀

Indeed, two different things. Although my teacher is firmly convinced they are the same. But I don’t belive him – he doesn’t know that much…….

I hate stupid teachers, lol. I had one of those the past few years.

Ok then;

5.Cytosol ………Essential to keep organells working..

still. why did you include the cell wall?

Cell membrane is more important than cell wall ??

aah.. yes. think of it: do you know any cells without a cell wall? yes. How about without a cell membrane? No

lol; there is no option of "cell wall" in initial post…….. 😮

I have thought of that before popsting my answer…lol…. 🙄

Go and see first post carefully…. 😯

maybe you should get your eyes checked :p
There is cell wall in the initial post

Oh sorry typing mistake……… 😳

Not "cell wall"…….. I want to say "cell membrane"……….. 😮

That was the matter of issue……… 😉

My eyes are well yet…….. No spects since.. 🙄

Now say………. what you were saying?…. 😮

Exactly ! So cell mebrane IS more important.

I know its important ………. but there was no option of cell membrane but cell wall……. so I selected that……….

Please for give me…. 😥

yeah… im wondering why cell wall is on the list but not the cell membrane… 🙄

Check the organelles in the genus Mycoplamas. Simplest free living organism. Other than terminal organelle will probably be close

he meant Mycoplasma. And they are parasytes from what i know, not free living.
By the way, how many ribosomes does a mycoplasma have? cause it says in campbell that one of those little buggers is only 5 times as big as a ribosome. where do the DNA, ribosomes, enzymes and everything fit in that small space?

Easy..ya…all organel realy need..well more importantly is Nucleus,RER,membrane,mitocondria and Centrioles..rite..well,about ribosome.RER hv ribosome already..if doing an essay question can write more about any organel..

Moderator…He asked for pick the organel,this is main thing he want to it..perhaps need explaination

centrioles? Buy new books buddy. Centrioles are not absolutely necessary for any cell. Plant cells don’t have them at all. And if you distroy them in an animal cell, the cell still divides by mitosis.

Ooic…well,i thought centrioles is important…*shy*

Erm..today i ask my lecturer..he noticed about the centrioles..if dun hv at plant cell stil can divide by mitosis but in animal muz hv centrioles.Its that correct?

NO. experimental procedures have shown that if you use a laser to distroy the centrioles of an animal cell it will still divide.
Actually, according to Molecular Biology of the Cell a spindle can form with no problems even without centrosomes. It is called a bipolar spindle, and it has provided evidence that chromosomes play an active role in spindle formation…

OOh i see…thanks for ur information.Now i more know about it
