HELP ME !! IS THERE ANY STAGE OF A BLOOD CELL (ERYTROCITE) WHERE THE RED BLOOD CELL HAS ORGANELLES E.X RIBOSOMES,NULEUS,MITOCHONDRIA,ENDOPLASMIC RETICULUM E.T.C

Hey @blues this looks like it might be a question that's up your alley. OP says he's been searching for about four hours and can't find a definite answer one way or the other. So I figured I'd help him out by mentioning you here. :)

http://wiki.answers.com/Q/Describe_the_stages_of_erythropoiesis Hope it will able to help u bit.

OpenStudy (faman39):

u can also post it over another awesome group

OpenStudy (faman39):

here. http://openstudy.com/study#/groups/AngelDreamGurl

OpenStudy (faman39):

if u post there, angeldreamgurl will sure help u when she will be online, she is good at bio.

OpenStudy (faman39):

actually really good at it!

For mammals, it would be the reticulocyte stage.

OpenStudy (anonymous):

soo in the reticulocyte stage , which organelles does it have?

OpenStudy (anonymous):

all of them, including the nucleus

OpenStudy (anonymous):

and in the previous stages it has nothing right?

OpenStudy (anonymous):

? reticulocytes turn into erythrocytes (red blood cells) by losing the nucleus and other organelles. Erythrocytes are the terminal stage. Reticulocytes come from erythropoeitic stem cells which have all organelles as well.

OpenStudy (anonymous):

ooh ook , soo after it looses the nucleus what happens ?

OpenStudy (anonymous):

it becomes a fully functional red blood cell

OpenStudy (anonymous):

which organelles does it have ?

OpenStudy (anonymous):

and what is hammoglobin?

OpenStudy (anonymous):

red blood cells are missing most organelles. They are sacks of hemoglobin, the protein that carries oxygen through the blood and releases oxygen to the cells in your body.

OpenStudy (anonymous):

thanks , but can you explain erythropoiesis please

OpenStudy (anonymous):

?

OpenStudy (anonymous):

What do you want to know about erythropoiesis? How much depth? Whole books have been written on this topic.

OpenStudy (anonymous):

I want to know how it starts and evolves and each steps names.

OpenStudy (anonymous):

Could look it up? Wikipedia is a good source to start.
