Science project: Creating a cell Cell membrane The cell membrane in the plant controls what comes into the cell. If something is needed the membrane lets the cell get past. In a plant, the membrane is surrounding the cytoplasm and the cell itself. The main function: The cell membrane has the important job to support the cell membrane and cytoskeleton inside of it. The membrane does the same job to the cytoplasm as it does to the cell. It lets some proteins in and keeps others out. In a plant, the membrane also serves an attachment to the cytoplasm. This means the membrane supports the cell and keeps it in shape. The membrane is made up of two parts, the internal and outer membrane. The outer membrane controls what comes in of the cell and how much of it is needed. The inner membrane supports the cell and controls the exchange of organelles from its cell to another. However, membranes are semi-permeable. This means that they allow very small molecules in even if not needed. Like oxygen and carbon molecules. The cell transport proteins to other cells that keeps the cell healthier. Other parts that help the membrane transport organelles are transmembrane proteins. These proteins are spread around the whole membrane. There are four types of transme mbrane proteins transporters, receptors, anchor and enzyme. Transporters carry one molecule to another. The enzyme transforms a molecule to a different form. An anchor protein can connect an outer molecule with an inner molecule. What are they made of; Cell membranes are made up of a phospholipids bilayer. The bilayer is made of many phospholipids side by side. The phospholipids has one glycerol two fatty acids and one phosphate heads. This compares to a †¦ Laser alarm: ... ...reate a chemical reaction to make NADPH and ATP. Now the dark reaction. The ATP from the light reaction is used to make carbohydrates from hydrogen. The carbohydrates posses and energy that are given by the ATP and NADPH. This carbohydrate has the chemical energy to make glucose (sugar) that is the main source of their food. The chloroplast’s ability to do the process photosynthesis is not only helpful to plant but to animals that eat plants. This because a plant cannot live without food and an animal’s food is a plant. What is it made of: A chloroplast is made up of lipids and protein membranes that are folded in a complex way. This compares to a: Solar panel: Similarities: †¢ Converts sun light to energy †¢ Just like the chloroplast, the solar panel stores the energy from the day so they can use it for the night too. †¢
