Today, Daniel and I finished our cell song project in school. We started off listening to songs of different style and narrowed the list down to 3 songs: Candy by Robbie Williams, Starships by Nicki Minaj, and Domino by Jessie J. We chose Candy in the end, because neither of us knows how to rap and this song is rather catchy. We try to write 2 - 3 lines (1 for structure and 1 for function) for every organelles and a chorus devoted to cell membrane because we spend an significant amount of class time on cell membranes.

After an entire afternoon of hard work, here is our final product.

Candy – Robbie Williams 
Cells are smallest unit
Nucleolus holds the center
And it makes ribosomes
And it holds DNA
Rough ER makes the protein
Ribosomes are on it
It has a lot of membrane
It connects the nucleus
Golgi body labels proteins
Exports them
It looks like flattened sacs
Smooth ER is like the rough ER
Makes the lipid
And it is smooth
-------------------
Mito mitochondria
It does the respiration
It looks just like a peanut
It has a double membrane
Cyto Cytoskeleton
Made of microfilament 
It gives the shape of support
It helps to move the organelles
Vesicles do transportation
They are small
But the vacuoles do the storage
Small in animals
They’re enormous in plant
And there’s chloroplast
It does photosynthesis
------------------------------------------
Centrioles are in animal’s cells 
They are near the nucleus
It separates the chromosome pairs
Cytoplasm
Is a bloody liquid
And it is everywhere
Protects organelles
Supports organelles
Protects organelles
Supports organelles
What are we doing this for?
What are we doing this for?
'Cause we love cells
'Cause we love Mr. C
'Cause we love you
-------------------------
(----- Represents the chorus)

Chorus
Hey ho cell membrane
I’m phospholipid 
I’m phospholipid 
I protect the cell and make things flow
Cells can’t do without me
Hey ho hers a cell
Either a little too big or a little too small
There’s a plant cell and an animal cell
And we think they taste like CANDY!

Important Misconceptions:
I personally think that this project is extremely helpful. It helps me revised and able to remember functions and structures organelles. Singing this song again and again, I know nearly all the basic information about cells already.

Today, we start to talk about homeostasis and how our body work 

• what is homeostasis
• the ability to maintain stability of the internal system to respond to external disturbance 
• from Greek: ὅμοιος, hómoios, “similar” and στάσις, stásis, “standing still”
• How is homeostasis maintained?
• organ coordinate
• How complex is human body
• organelle to cell to tissue to organ to organ system to whole organism

Cell

• most basic form of life

Tissue

• a group of similar cells and cell product that arise from the same region of the embryo and work together to perform a specific structural or physiological role in an organ
• these tissue differ from each other in the types and function of their cels, the characteristics of the matrix (extracellular material) that surround the cell and the relative amount of space occurred by cell versus matrix.

Organ

• An organ consists of several tissues that together perform a specific task

Organism

• Different organ systems work together, contributing to the successful function of the whole organism.

What we’re going to learn:
1. Levels of organization
2. Systems of the body
3. Body’s control mechanisms
4. Human system disruption and imbalance of homeostasis
5. Different cells, structures, and functions.


Important Misconception
Although I've heard the concept of homeostasis before in The BigBang Theory, it is a new topic for me. The cells, tissues, organs and systems work together to maintain homeostasis.

The focus of the lesson on Friday was on transfer of molecules in and out of the cell membrane. What I learnt was that plasma membrane allow what the cell needs come through and block what it does not need. 

• plasma membrane
• genetic function
• protection
• in and out
• specific
• transporter
• enzyme
• intercellular jointing
• • phospholipid bilayer
  • The lipid bilayer acts as a barrier that water cannot cross
  • The hydrophobic tails of phospholipid molecules are sandwiched between two layers of hydrophilic heads
  • Cell membranes consist primarily of lipid bilayers
• tails
• non polar = none charged
• hydrophilic
• heads
• polar
• hydrophobic
• cell needs:
• O2
• Sugar
• Na
• H2O
• out of the cell
• protein
• lipids
• H2O
• Cl-
• amino acid
• pass through 
• (Because the concentration difference between in and out have to be balanced)
• Diffusion 
• O2
• CO2
• N2
• Ethanol
• Glycerol
• dont pass through
• Glucose
• H
• Na
• Ca
• Cl
• Amino acid

Misconception: Something confuses me. Mr. C wrote on the board the things a cell needs, such as Na and Sugar, but some of these things don't pass through the cell membrane. I don't quite understand.
