The cell membrane is a structure that controls what enters and leaves the cell. In a basketball stadium, the security guards are like the cell membrane. They can say who comes in if they don’t cause any problems and are following the rules and they can reject them and make them leave if they have something they aren’t supposed to or they are doing something wrong. This is how security guards are like a plant cell’s cell membrane because the security guards control what enters and leaves the stadium like the membrane controls what enters and leaves 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

In a basketball stadium, the stadium walls are like the cell walls. The stadium wall surrounds the stadium and helps support the structure. This is how the cell wall and the stadium wall are alike because they both provide support to the structure and they both surround their structure.
Chloroplasts are and organelle that contains chlorophyll, and is the place where photosynthesis takes place. In a basketball stadium, the concession stands are like chloroplasts. The concession stands is like chloroplast because it makes food for everyone at the game. This is how chloroplasts and the concession stands are alike because they both make food.
Cytoplasm is a jelly-like fluid inside the cell in which the organelles are suspended. All life activities except reproduction happen here. In a basketball stadium the fans are like cytoplasm in a plant cell. The fans are like cytoplasm because they are all over the stadium like cytoplasm is all over the plant cell. This is how cytoplasm is like the fans because they both are all around the
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
to construct and or maintain the cell membrane. In a microscopic view of the cell membrane we can
parts, and each part has its own job. The nucleus of a cell is very similar
This cell membrane plays an important part in Diffusion. Cell membrane and Diffusion Diffusion is the movement of the molecules of gas or liquids from a higher concentrated region to a lower concentration through the partially permeable cell membrane along a concentraion gradient. This explanation is in the diagram shown below: [IMAGE] Turgor When a plant cell is placed in a dilute solution or a less concentrated solution then the water particles pass through the partially permeable membrane and fill the cell up with water. The cell then becomes Turgor or hard. An example of this is a strong well-watered plant.
In the most general terms, the nucleus is the command center of a eukaryotic cell. Although the origin of the organelle is unclear, it is believed that it is derived from a symbiosis relationship between a bacterium and an archaea (Martin W. 2005). Being the main hub for the inner workings of a cell involves different functions overall. These nucleic functions are determined by the genes within the DNA of the cell. Functions of the cell are also regulate by soluble proteins that come in and out of the cell via the membranes and specific channels or the nuclear pore complexes. The overall objectives of the nucleus include; gene expression, compartmentalization, and processing pre-mRNA. The functions of the organelles and sub-regions
The Cell or plasma membrane is not a solid structure, but made up of proteins that form channels and pores. In addition, carbohydrate molecules serve as recognition of cells and cholesterol molecules contribute to the stability of the membrane. The structure consists mostly of phospholipid molecules. The membrane separates the interior of all cells from the outside environment.
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 contains genetic material that controls all the activities within a cell. A nucleus is made up of D...
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.
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.
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 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.
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.
Their main purpose is to survive and their functions allow them to do so. All cells have common features whether they are eukaryotic or prokaryotic cells. The common features include a plasma membrane, cytoplasm, ribosomes, and DNA. A plasma membrane which is also known as a cellular membrane, surrounds all cells and its primary function is to protect them. Plasma membrane is made up of two layers of phospholipids which are a class of lipids and has many proteins embedded in it. The proteins have a function of providing support and shape to a cell. There are three different proteins in cell membranes (see appendix 1). The plasma membrane also regulates the entry and exit of the cell, as many molecules cross the cell membrane by osmosis and
