I am taking biology for the first time. Would someone explain to me what the term organelle means and how it is identified in cells?
March 18, 2006 at 10:03 am #43644asutoshsahuParticipant
Small organ in a cell which is responsible for certain activity of the cell
For eg. Mitochondri is an organell which is responsible for storage of energy.
similarly Nucleus for controlling all cellular activity.
I think it will help you

actually mithocondria doesn’t store anything. It just releases energy stored in organic bonds.

When somebody says organelles they are talking about Eukaryotic cells, Because Prokaryotic cells have no organelles. But if you want to know more about them just search the internet!

i thought prokaryotic cells only doesn’t contain membrane-bond organelles. actually. is there organelle that is non-membrane bond even in eukaryotic cells?

That is a good question to which I don’t know the answer to. I’m sorry I really wish I did know that answer to that.

Hi there…I teach anatomy and physiology…amongst other things. I basically tell my students that organelles are the mini-organs for the cell. Just like our body has a brain, a stomach and an immune system…our cells have the same….these organelles.
For instance, the nucleus is the "brain"…it stores information, the lysosomes are the "stomach" that breaks down proteins and carbs…and the golgi aparatus is the "immune system" that engulfs or packages up all the bad stuff…(inclusion bodies).
I hope that makes some sense to you. 😀

Non-membrane bound organelles? Sure. Ribosoms. The centrosome(although it too is absent from the prokaryotic cell).
The golgi=immune system? Hmm…Immune system secrets substances and i didn’t know? 😉
March 20, 2006 at 7:06 pm #43811
I was kind of aiming more towards the general "getting rid of stuff that doesn’t belong" LOL!
March 20, 2006 at 7:17 pm #43816
Hmm.. I would say lisosoms do that more. The golgi apparatus does get rid of stuff that doesn;t belong there, but the main difference is it sends them somewhere else while the immune system distroies them… But it would be a shame to distroy things that were meant to be secreted… 😆
March 20, 2006 at 9:15 pm #43827
But the golgi packages them up…like "sealing their fate" so to speak….
I always bring up inclusion bodies to help explain it better….

Organalles are tiny cell structures within the cytoplasm that are specialized to carry out a function.
March 29, 2006 at 3:30 am #44503kiekyonParticipant
organelle=specific, usually subcellular, particles of membrane-bound organised living substances present in practically all eukaryotic cells, including mitochondria, the golgi complex, endoplasmic reticulum, lysosomes, centrioles and the cell centre, as well as the plastids of plant cells. Includes also the minute organs of protozoa concerned with such functions as locomotion and metabolism.

Ooops My mistake sorry. Mised the first page of the question And was wondering what this message was about.
