P1: Outline the functions of the main cell compounds
What is a cell?
Cells are the basic building blocks of all living things. The human body is made of millions and billions of these tiny little cells. These tiny little cells which doesn’t look like it can do much plays a big role in our bodies, It is what helps provide a good structure to our bodies, aids in converting nutrients from the food we eat into energy, and all have their own individual functions. There are many different types of cells such as human body cells, animal cells and plant cells, each with their own role. In this essay i will be assessing the components of an animal cell and will be evaluating each component in further detail to get a detailed understanding of it all. The animal cell contains the following components.
Animal cell
Nucleus
The nucleus is the largest structure in a cell; however some cells may have more than one nucleus such as red blood cell whilst cells such as bacteria cells have no nucleus. The nucleus being one of the most important parts of a cell is found in the middle of the cell containing DNA; the DNA is like the control room of each cell, giving orders to the cell; telling the cell to grow, die etc. The nucleus is then covered by a nucleus envelope; this envelope gives protection to the DNA which is inside the nucleus, the nucleus envelope also disconnects the nucleus from the rest of the cell. The nucleus in the animal cell also controls the animal’s cell growth, reproduction and metabolism.
Vacuole
Vacuoles are sac-like substances found in cells, they are found in both plant and animal cells but mainly in plant cells. These sacs are food storages for the cell, not only do they store food but at times hold in the waste produc...

Cell membrane
The cell membrane is likened to a door of a house; it is there to keep everything within the cell safe and kept protected from any unwanted substances such as bacteria, there are also holes which allow the fluid and cell pieces inside and prevents any unwanted things from entering, the holes are there to allow certain things in and out of the cell.
Cytoplasm
Cytoplasm is a substance that fills the inner space of the cell. Cytoplasm holds a firm structure for the inner cell; it contains protein filaments known as cytoskeleton which also assist in maintaining the shape and consistency of the cell. Apart from storing nutrient, cellular reactions take place within the cytoplasm such as protein synthesis.
The building of the grocery store is like the cell membrane, because it gives it structure and keeps everything inside safe. The security guard of the front door in the grocery store is like the cell membrane, because it says what can come in and out of the cell. The boss of the store is like the nucleus, because they tell the employes what to do and what needs to be done. The floors of the grocery store is like the cytoplasm, because it hold everything in it place, where it need to be. The illes in the store is
Question 1: Briefly describe, in 500 words or less, the normal structure and function of your chosen cell type. In your answer, discuss specific features in your chosen cell type, including cell organelles.

parts, and each part has its own job. The nucleus of a cell is very similar
The most important and largest cellular organelle is the nucleus, which houses most of the eukaryotic cell’s DNA and is surrounded by a double membrane. The nucleus contains most of the cells genetic material. The nucleus is the control center of the cell.

The nucleus is a organelle that controls all life activities, especially reproduction. In a basketball stadium, the head coach is like the nucleus. The head coach controls everything that happens especially what his team does. This is how the
The nucleus is the CEO of the cell. It controls all cell activity, It regulates movement, reproduction, and eating in the cell. The nucleus contains the of the cell's genetic information. This information is organized as deoxyribonucleic acid molecules, in conjunction with a spread of proteins, to create chromosomes.
to construct and or maintain the cell membrane. In a microscopic view of the cell membrane we can
Cells are able to grow and reproduce. Cells reproduce by splitting and passing on their genes (hereditary information) to Daughter cells. The nucleus always divides before the rest of the cell divides. Therefore each daughter cell contains their own nucleus. The nucleus controls the cells activities through the genetic material DNA. The cells in a body are all the same except the gametes they were all made from one cell, the Zygote. This is the cell that was formed when two gametes from your parents fused.
The membrane surrounding the nucleus in eukaryotic cells, separate the nucleus from the cytoplasm. Most of the cells we used in the experiments held, were multicellular or consisting of more than one cell. A variety of cells were used in completing the experiments. We used union cells, cheek cells, potato cells, and Elodeo cells. We also used Planaria which is a unicellular organism.
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. But it also contains highly organized physical structures which are called intracellular organelles. These organelles are important for cellular function. For instance Mitochondria is the one of most important organelle of the cell. Without Mitochondria more than 95% of the cell’s energy, which release from nutrients would cease immediately [Guyton et al. 2007].
The nucleus is often the largest organelle found in a Eukaryotic cell with a size of 10-20 un. It is surrounded by two membrane layers which can be identified on the diagram below. Within the nucleus structure are small pores with a size of 100un in diameter. These pores together make up around one third of the nuclear membrane surface area.
The Animal Cell is a little bit different than the Plant Cell for only a couple of reasons. One is how the Plant Cell has a cell wall and the Animal Cell doesn’t. The cell wall protects and gives structure to the cell. Then there is the Nucleus, which serves as a control center for the cell. Inside the Nucleus there are one or more Nucleoli. They are dense, granular bodies that disappear at the beginning of cell division and reappear at the end. Then you have the Cytoplasm. This is the watery material lying within the cell between the cell membrane and the nucleus. The Cytoplasm also contains organelles, which have specific functions in the cell metabolism. Then there are the Golgi Bodies, which serve as processing, packaging, and storage for the cell. These organelles package and ship things out. Another parts of the cell, a very important one in fact, are the Lysosomes. These organelles are used to break things down and contain enzymes.
