Eukaryotic Cells Draw, Label and define functions of: (Cell Membrane and organelles) Cell Membrane-The membrane is made up of lipids and cholesterol, but also is composed of proteins. The functions of the cell membrane are to provide receptors for hormones and other biologically active substances, participate in the electrical events that occur in nerve and muscle cells, and aid in the regulation of cell growth and proliferation. Also, helps to control what can enter and leave the cell, which makes it selectively permeable. Nucleus-The nucleus is normally located in the center of the cell. It is enclosed by a nuclear envelope and contains chromatin within. It contains the DNA which is important because that helps to synthesis proteins that must be produced to keep the cell alive. Cytoplasm-Is known as the work space for cell. The main components of the cytoplasm are cytosol-gel like substance. The cytoplasm is about 80% water and usually colorless. The functions of the cytoplasm are to remove waste material, help in cell respiration, and convert glucose into energy. Cytoskeleton-This is responsible for the cell shape, movement and cell as a whole. The function of this is to help move things in and out of the cell. Lysosomes-These are found in the cytoplasm of the cell. This part of the cell helps with the digestive of worn-out cell parts, excess parts, and foreign substances that might enter the cell. Mitochondria-Known as the powerhouse of the cell. It is located in the cytoplasm of the cell. The functions of the mitochondria are to help with cellular respiration, generate ATP, and are key regulators of apoptosis. Golgi apparatus/Complex-This is an organelle found in mostly eukaryotic cells. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus. The functions of this part of the cell are to help sort and package proteins for secretion. It also helps to transport of lipids around the cell and the creation of lysosomes. Peroxisomes-Contains enzymes that are used to help oxidative reactions. Help to breakdown fatty acids, which are ineffectively degraded by mitochondrial enzymes. Found in the cytoplasm of almost all eukaryotic cells. Ribosomes-Ribosomes are located in the cytoplasm but also are bound to the Rough Endoplasmic reticulum. Which is why it is called rough ER. Ribosomes are the cell structure that makes up proteins. Protein is needed for many of the cell functions.
