Let’s Take A Tour Through The Bushey’s Cell!

Our Lovely Cell

Every cell is enclosed in a membrane, a double layer of phospholipids (bilayer). The exposed heads of the bilayer are “hydrophilic” (love water), meaning that they are compatible with the extra cellular fluid (ECF) and cytosol . However, the hidden tails of the phospholipds are “hydrophobic” (hate water) so they face away from the ECF and cytosol. This bilayer makes a protective barrier. The plasma membrane also contains proteins which are busy transmitting info from cell to cell.

Plasma Membrane

The Exterior Walls of Our House

act as the hydrophilic "head" region facing the extracellular fluid (The Rain & Snow).

The Interior Walls of Our Houseact as the hydrophilic "head" region facing the cytoplasm (bath time, leaky

pipes, overflowing sinks, kids in general always find a way to make things wet!)

The Guts of our walls act as the hydrophobic "tail" region, they also contain transmembrane proteins (window transmits chemical messages) and cholesterol (I guess

the insulation, fat keeps us warm?)

Ion Channelsare transmembrane proteins that allow water and dissolved ions to pass through the membrane. Some channels are always open and

some have gates that open and close under different circumstances. The gates respond to 3 different stimuli. Ligand-regulated gates

respond to chemical messages, voltage-regulated gates change with voltage across the plasma membrane, and mechanically regulated

gates respond to physical stress on the membrane.

Our Front Door acts like a Gated Ion Channel, it opens and closes to allow ions through when needed, and

keeps the bad guys out!

Closed Gate Open Gate

Cytoplasm is the liquid inside the cell (cytosol) and all the organelles put

together. It makes up 70% of the cells volume.

The inside of our home is the cytoplasm, but even more comparable would be my kids in

an overflowing bubble bath!

Cytoskeleton Is made up of 3 protein filaments, actin, microtubules, and intermediate. It

provides structure that maintains cell shape, protects the cell, enables cellular motion and plays important roles in intracellular transport.

The Cytoskeleton

The beams give support & shape.The frame work gives structure, and helps organize the contents.

Nucleusit is sometimes referred to as the "control center”, it contains most of the cell's genetic material. The function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell - the nucleus is therefore the control center of the cell. It has a nuclear envelope otherwise known as

nuclear membrane which consists of two cellular membranes, an inner and an outer.

My Husband and Iact as the “Nucleus”

We hold the genetic material known as DNA. We also are the decision makers of the house, we give out orders.

Together our Genes make……well we wont go there today!

Rough Endoplasmic Reticulum (ER)are responsible for protein synthesis and have many ribosomes on its

outer surface.

Eat your protein!my ribosomes chowing down on a chunk of protein (not really)!

Smooth Endoplasmic Reticulum (ER)is responsible for lipid synthesis, detoxification, and calcium storage. It does

not have ribosomes attached to it as the Rough ER does.

Our fridgeacts as the Smooth ER because it holds lipids, and lots of calcium.

Ribosomesare packets of RNA, and Protein. They are

responsible for protein synthesis.

Our Kids act as our little ribosomes because they contain RNA which is very

similar to our DNA. They are always busy running here and there and transferring information (and delivering messes throughout our cell)!

Golgi Complex/VesiclesThese are the “packagers”, the golgi complex collects and then

packages cell products in the golgi vesicles and carries cell products to the surface or turns them into lysosomes.

Our Mud Roomacts like the Golgi Complex/Vesicles because this is where

everything is packaged up before it leaves our cell.

Lysosomesare the cells “garbage disposal system”. They digest dead or unused

proteins and foreign bacteria (or other forms of waste) that invade the cell.

Our Garbage cans and toilets act as Lysosomes, they get rid of

the waste and products no longer needed (sorry guys)!

Peroxisomesare responsible for protecting the cell from its own production of toxic hydrogen peroxide. White blood cells produce hydrogen peroxide to kill of bacteria. The enzymes in peroxisomes break these down into water and

oxygen. Basically they get rid of the bad stuff!

Our Dog Remmie acts as a peroxisome he doesn’t like the bad guys, he chases them out

when they come in!.

Mitochondriaare sometimes described as the "power house" because they generate most of the cell's supply of ATP. Like the nucleus it is surrounded by a double unit membrane.

Our wood stove & Electrical Panel Box acts as the Mitochondria, together they act as the “power house” we couldn’t function

without them.

Centriolesplay a roll in cell division. They are assembled in 9 groups of 3

microtubules fused together. Two centrioles lie perpendicular to each other within a small clear area called the centrosome.

The Twinsact as centrioles because as a zygote the egg divides (yeah I know they are

fraternal, you get what I mean)!

We Hope You Enjoyed The Tour Of “The Bushey’s Cell”

and Learned Lots About Our Forms and Functions!!

Lisa & Her Ribosomes

Bye! We hope you come again!
