Answer 2

Hey Newbie :)

Answer 3

One will be ribosome !

Answer 4

Can u guess one more ?

Answer 5

One more will be centriole

Answer 6

Well you have ribosome, cytoskeleton, flagellum, centriole, microtubule-organising centre. But yeah I agree with Abhisar, commonly the major one is ribosome.

Answer 7

Cytoskeleton ????

Answer 8

yeah.....

Answer 9

I didn't knew there is an organelle named cytoskeleton !

Answer 10

.....

Answer 11

are u talking about endoplasmic reticulum ?

Answer 12

Cytoskeleton of a cell is not an individual thing...It is collectively formed by many organelles like E.R, microtubules etc.

Answer 13

@PRAETORIAN.10

Answer 14

this is the definition copied and pasted: a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.

Answer 16

all these people agree that its an organell

Answer 17

@Abhisar

Answer 18

@PRAETORIAN.10 see on each reply there is a thumbs down. They themselves say 'contains microtubules and microfilaments.'

Answer 19

Don't just go by yahoo answers they are not reliable source.

Answer 21

@PRAETORIAN.10

Answer 22

all science is incomplete. doesnt have to be incorrect.

Answer 23

Dear @PRAETORIAN.10 Cytoskeleton is a compound word made from Cyto + Skeleton which represents the supportive structures inside the cell. these include, E.R, microtubules, microfilaments etc.

Answer 24

yeah, well done.

Answer 25

Yeah, cytoplasm is not an organelle.

Answer 26

A ribosome is also not a cell nor an organelle - it's a ribonucleoprotein, sometimes called ribozyme.

Answer 27

go ahead and rub it in some more........

Answer 28

jeez

Answer 29

lol sorry, thats the first answer i read and i had to point it out.

Answer 30

why does it say "cells" in the question and you're all listing organelles? because of common sense? ^^

if we're listing organelles that are not bound to a the cell membrane, then practically everything works. chloroplasts, mitochondria, the golgi...are all not attached to the cell membrane.

if we're talking cells that swim freely throughout the body, then all kinds of blood cells fit as answer, because they are not bound to any tissue by interaction of the ECM.

Answer 31

@aaronq The whole "ribosome is an organelle/is not an organelle" is just a matter of opinion. It does get called a non-membrane bound organelle by some. Many prefer leave it out, keeping more in the etymology of organelle.

Answer 32

@schleifspur You have a serious misconception about cellular components. When we say "membrane bound" we do not mean attached or partially inside the cell membrane. We mean that the organelle has a completely separate lipid bilayer. Do you know the theory of endosymbiosis? If you read that you will find out all of this and why it is thought that these organelles are in Eukaryotes.

Answer 33

I don't think I do :)

and I also think that we all got confused by the way the question was phrased.

'name 2 membrane NOT bounded CELLS'

I've stated before that it says "cells" in the question. If you're talking organelles, then the question makes no sense at all:
If I go by your definition of membrane-bound, then every organelle is membrane-bound since it's the nature of innercellular borders to consist of membranes. and even if you consider microtubules and centrioles als organelles (which is very debatable), then you will find that they are also mostly membrane-anchored.
And if I go by my definition of membrane-bound, then you could choose between every classical organelle (nucleus/vesicle/mito/chloroplast/ER/golgi/lysosome).

either way, IT SAYS CELL. and I think we got trolled here, guys. :-)
