Transcript of Cell
A Journey Through The Cell
By: Bailee Shiring, Grace Collins, Chase Ollenburger, Trinity Tang, and Sarah King
First we encounter the cell membrane
Sarah notices while we approach that the outermost layer, the cell membrane, is
controlling the movement of materials
and that it is the
of the cell. From Trinity's previous studies, she mentioned that the membrane helps
and is for
from outside forces.
Also with Trinity's extensive studies she adds that the membrane has a double layer of
phospholipids with proteins
, so we can breach the membrane with some ease.
We almost immediately run into this
clear, thick, jelly-like
inside the membrane
expanding so far through the cell that from where we are we could not see the end.
Grace notices the small fiber-like objects floating around. Bailee points out that those small fiber-like objects are the
Bailee identifies that the cytoplasm is for
We slow down in the cytoplasm
Chase, the pilot, now points out that we are passing a humongous highway-like organelle that is called the endoplasmic reticulum (ER).
He sees one type of ER that appears rough and he does not know why.
Sarah comments that the rough ER is "rough" because
there are ribosomes
that attaches to it.
Sarah continues, saying that the ER
makes proteins because it is a network of tubes and membranes.
It is hard getting through the ribosome-filled rough ER, but now there is another form of ER. It is very similar, but
with no ribosomes.
Chase slows our speed while we approach the nuclear envelope, also known as the nuclear membrane.
The first thing we notice when we emerge through the nuclear envelope in to the nucleus is that the
large, oval shaped
contains multiple nucleoli and DNA.
Venturing deep into the nucleus, we find numerous microscopic nucleoli.
As soon as we entered the cell we notice we are being followed, but do not know by what. Chase just now recognizes the organelle as a lysosome!
We are lost in what seems like a maze in the center of a mitochondria in the
inner folded cristae
organelle is difficult to get through, but manageable.
In the mitochondria, with the
inner surface area
aerobic cellular respiration
and all the reactions of
breaking sugar down to useable energy,
we have a little trouble getting through.
The smooth ER has an
extensive network of tubes and membrane
, the exact same as rough ER.
This form of ER still
carries material throughout the cell
, but does not make proteins.
Knowing this will be the hardest part of the cell to bypass because the membrane controls
movement of materials in and out of the nucleus,
Trinity presses the button that will change our metal ship into a form of RNA.
We do this because the membrane is
protecting and surrounding the nucleus.
This organelle, explained Sarah,
controls all cell activities
much like a brain in our bodies and
contains all of the hereditary information of the cell.
Science, not knowing much about these organelles, says these tiny organelles,
in the nucleus, make proteins.
disappear during cell division
, but reappear in both cells when split.
Bailee, hungry because she missed breakfast, points out that the Golgi body, identified by Trinity, looks like
on top of each other.
Bailee also explains that the pancake-looking organelle
brings in and modifies, repackages, and ships out proteins.
Chase, the driver he is, runs in to one of the few vacuoles in the cell!
fluid filled sacs
food, water, metabolic toxic wastes, and store materials
need for out cells to function.
Through our search for teams missing peer, we keep seeing ribosomes in various places and wondered what the organelle does.
So Grace radios in to the base asking what these organelles do and why we keep seeing?
Base mentions that ribosomes
are made of proteins and RNA
. Also, located in two different places across the cell. They first are located
around in the cytoplasm.
But if ribosomes are not in the cytoplasm, then they are
attached to ER
making the ER rough.
This means the small, round organelle is out to get us. The lysosme wants to maintain homeostasis, and to do that we can not be here.
This organelles other "jobs" are to
break down larger food molecules into smaller ones
digest old cell parts that are of no use anymore.
The single membrane lysosome is also a protein marker and receptor, but worse of all it is out to get us!
traces of the missing scientist!
Where are you???
We are being
by the lysosome
But who do we see at the far edge of the organelle?
Our missing student!
The lysosome is trying to capture us to
and do its job as
"the clean up crew"
We are being consumed by the lysosome!
But what do we see on the far edge...
Only the missing scientist!
But now how do we get out???
