Hey! I’m Plasmy, the Endoplasmic Reticulum!
I’m a very important organelle found in all eukaryotic organisms
including you.
That’s right. I’m INSIDE you right now, keeping you alive.
Cool right?
I’m a network of sacs and thin tubes that are found all
over your cell. I make up about 10% of every one of
your cells.
That’s all great and all but your probably wondering
what I do…
I’m responsible for the production, processing and transportation of proteins, lipids and I even transport
some carbohydrates.
How do I manage all of this work?
I actually have a buddy who helps me with all of this
work…
I’m SMOOTH ER!
and I’m rough er…
Before we go on, your probably wondering why we keep changing appearances.
why is my bubble so
much smaller…
It’s because ER looks different in each type of cell depending
on the cells function.
and why am I on the
bottom…
Moving on… lets take a closer look at ourselves!
oh no… I look terrible in this
picture…
That’s me right there… the layers of squished sacs…the yellow speckles
give me my name…
I’m the smooth wiggly tubes on the left!
That’s where my name
comes from too!
Smooth ER
Rough ER
Nucleic Membrane
Rough ER
Ribosomes are the green dots
Smooth ER in orange
Did you see the resemblance?
obviously not…
We’ll both talk about ourselves and tell you about
what we do. Take it away rough ER…
fine…
hmm… lots of space up here… anyways, those
yellow speckles you saw on me in the picture are
called ribosomes…
nom nom nom…
ribosomes help me create and synthesize
proteins from RNA, copies of DNA…
nom nom nom…
with the help of ribosomes, I synthesize and package proteins so they’re ready to be used
by cells…
yummy…
This is where smooth ER comes into the picture
Oh my turn!
I take the newly synthesized proteins and ship them around the cell where they’re needed
♩ ♩ ♪♫♬♫ ♪♫ ♪
I can also ship them through the cell membrane to other
cells.
♩ ♩ ♪♫♬♫ ♪♫ ♪
Not only do I ship proteins around, but I also produce
lipids and metabolize carbohydrates sand steroids.
no need to brag…
In addition to that, I also detoxify cells from drugs and
poisons!
how modest…
I guess you can think of me like a postal service…
and me as a factory…
I deliver everything where it needs to go
and you would have nothing to
deliver if not for me…
Well, that’s about it! Nice to meet you! Bye!
actually, we still know
nothing about you…
