The phospholipids make the basic bag. The proteins are found around the holes and help move molecules in and out of the cell. Cytoplasm This is a fluid that contains a simple mixture of chemicals and nutrients that are the basic living materials for the cell. All organelles are suspended within this. It moves materials around within the cell.
Rough ER transports these proteins to the regions in the cell where it is needed. | Ribosomes | A ribosome is composed of two parts known as the large and small subunits. Each of these is a combination of protein and a type of RNA known as rRNA. | the main thing they do is that they arrange the strands of the amino acids for use of the other parts of the cell and ultimately the body. | Goigi Apparatus | The main function of the Golgi apparatus is to be responsible for handling the macromolecules that are required for proper cell functioning | It packages and ships molecules made in the ER.
stores proteins and alot of exporting (sending stuff out of the cell) 3. In which part of the cell would you expect to find nucleotides? building block for DNA, DNA found in the nucleus 4. Name the two organelles involved in energy conversion.chloroplast and mitochondria 5. What are the basic functions of the organelles in chapter 4?
Information will always start with DNA then it will travel to the RNA and then the protein. This information flow will also be followed through the cell as it travels from the DNA in the nucleus, and the Cytoplasm, then to the Ribosomes and the Endoplasmic Reticulum, and finally to the Golgi
| | | A) | provides a location for DNA production | | | B) | helps decrease surface area | | | C) | allows selective permeability of cell membrane | | | D) | facilitates breakdown of chemical bonds | | | | | | Feedback: The pleats and folds of the endoplasmic reticulum provides a large surface area where cellular functions, such as breaking chemical bonds, can take place. |

P1- Describe the microstructure of a typical animal cell and the functions of the main cell components. The microstructure of a typical animal cell consists of a plasma membrane which is made up of two phospholid molecules, proteins and cholesterol. They form a lipid bilayer which is semi-permeable allowing only certain molecules to diffuse across the membrance. Cholesterol helps ‘to stiffen plasma membranes and is not found in the membranes of plant cells.’ Bailey, About.com. The nucleus regulates all cell activity and is bounded by a double membrane called the nuclear envelope, this membrane separates the contents of the nucleus from the cytoplasm.
Golgi body: The Golgi body is an organelle found in most eukaryotic cells. The Golgi body has numerous functions, such as sorting and progressing protein. While present in the Golgi body, they are processed and sent throughout the cell. The Golgi body is also responsible for deciding which proteins are to be transported outside the cell. Cytoplasm: Cytoplasm is a jelly-like liquid which is made up mostly of water and salt.
The plasma membrane acts as a selective barrier between the cell and its environment, and is a structure that you will study in detail throughout the year. The nucleus consists of a limiting double bilayer nuclear envelope containing nuclear pores enclosing the nucleoplasm. Small, irregular particles scattered throughout the nucleus or accumulated adjacent to the nuclear envelope are clumps of condensed chromatin known as heterochromatin. They consist of protein and DNA and stain with basic dyes. When the chromatin is dispersed and not readily stainable, it is known as euchromatin.
| The word Ribosomes remind me of Ribs. Then I think of protein which leads me to the definition. | Endoplasmic Reticulum | The Endoplasmic Reticulum is a bunch of membranes inside of a cells. It's function is mainly manufacturing and packing. | | Golgi Apparatus | Golgi Apparatus creates lysosomes which helps with digestion.
