Q2(B)
The advantage of having a cell wall in an animal cell is that the cell wall will be able to protect the cell from physical damages, since the cell membrane is not strong enough to withstand any damage done to it and also to support the cell. The cell wall also prevents expansion when water enters the cell and hence the cell does not burst unlike the animal cell.
But having cell walls in animal cells also have several disadvantages to the body as well. As the cell wall provides rigidity to the cell for structural and mechanical support, this will hinder our movements and we will find it virtually impossible to move.

Q1.Cell Analogy
In the Yolkel Restaurant, leaflets are pasted all over the restaurant indicating the job requirements. Manager Boon follows this and employs several cooks. The cooks whip up some good food and pass the food to the delivery men in styrofoam boxes. The delivery men is instructed by Mr Chong the supervisor who tells them where they should go. Sometimes if the food tastes revolting, it is thrown into the the dustbin. The door is watched by Mr Chua the security guard and he only allows certain people to go in or out such as the delivery men. The Yolkel Restaurant is powered by circuit breakers where electricity is channeled through from a SIMLIAN Power Station a few streets away from the restaurant.
The restaurant is the nucleus as it houses the manager and contains important instructions(leaflets) for chemical reactions. Manager Boon is the nucleolus as he "produces" the cooks, who are also the ribosomes, as they are in charge of making food(proteins). The food is then passed to the delivery men, who are also the rough endoplasmic reticulum, and they work together with supervisor Chong,the golgi apparatus, to deliver the food to their rightful destinations. Spoilt food is thrown into the dustbin,which serves the same function as the lysosomes as the food is broken up by bacteria in the dustbin. Mr Chua the security man acts as the plasma membrane, allowing only certain people to pass through. Lastly, the circuit breakers act as the mitochondria, converting electricity(food substances) into energy to be used by the restaurant.

1 Interesting Fact About Biology

Welcome to my first bio-blog post.
The interesting fact that I discovered about Biology is about the structures of life:cells. There are different types of studies regarding varying types of cells. They are molecular biology, cell biology, genetics and development biology.
Molecular biology is the study at a molecular level, and is basically about understanding the interactions between the various systems of a cell, including the interrelationship of DNA, RNA, and protein synthesis and learning how these interactions are regulated. Cell biology studies the "characteristics" of the cells, and also their interaction with other cells. The scientists study these cells by microscopic and molecular means. Our genes, heredity and the variation of organisms all come under "Genetics". Genetics serve as important tools in the investigation of the function of a particular gene. Genetic information is carried in chromosomes which is represented by DNA molecules. Genes are important as they synthesize proteins which will determine what an organism would look. The final study of our life structures is the development biology, which studies the processes by which organisms grow and develop.developmental biology studies the genetic control of cell growth, differentiation and morphogenesis which is the process where by the organs, tissues and anatomy are formed.
These are the four different types of studies on cells that I researched on the internet, which I found very interesting to read and know about.
