LAB- CELL MODEL- PARTS


PARTS OF THE CELL


My cell model is composed inside of a styro ball, the outer portion signifying the cell membrane. The right picture is my completed version. Below I will show different pictures relating to the functions and different parts of the cell as I pieced it together. A cell is a master piece; the tiny living cells reproduce numerous times, little messengers scurry around to process information to make replication of a new cell possible. I will also explain the process of mitosis and DNA replication.



The pink yarn represents the Goligi Apparatus: The structure is like an operation stand, it obeserves different objects received such as proteins and lipids, and adjusts/modifys them.




The pinks beads and the green styro are formed to make a mitochondria: This structure is like an Energizer Bunny. It coverts the energy of glucose into a chemical energy of ATP. It is also known for its function of cellular respiration, since the mitochondria drains up all the oxygen and is forced to release carbon dioxide.

The staples make up the endoplasmic reticulum and the beads represent ribosomes (with beads is the rough/without is smooth). The function of ER is to help transport molecules to different parts of the cell: the neighboring golgi apparatus. The rough ER synthesize proteins and form a vesicle and the smooth ER, synthesize lipids.
Pink yarn/ball make up the nucleus, an important part of a cell, which stores the genetic information. The microscopic parts inside of the nucleus are important for functioning and transporting. Later, I will discuss the process of DNA replication which involves the protein and messengers.



The black pipe cleaner represents the cilia. Which is like a watch dog for the cell, it has a sweeping motion which helps protect foreign particles from entering the cell. The green beads are vesicles and lysosomes. Vesicles travel around the cell, and drop off contents they collected from the golgi apparatus. The lysosomes are scattered around the cell, but are abundunt in WBC, where they eat(engulf) disease micro-molecules.
