Our body is made up of cells. Cells consist of 3 major parts namely the cell membrane, nucleus and the cytoplasm. The cell membrane is semipermeable which is selective to what substances can enter the cell. It is composed of a phospholipid bilayer, proteins, and carbohydrates. The Nucleus which is coined as the control center of the cells. The nucleus contains the genetic material necessary for replication. The cytoplasm has organelles that are embedded at the cytosol. Organelles are double membraned and perform specific functions. Organelles include the Mitochondrium, lysosome, Golgi apparatus, and the like. The Mitochondrium, a sausage-shaped

organelle, is the powerhouse of the cell in which cell respiration takes place. The lysosome is responsible for digesting foreign and dead materials for it possess enzymes. The Golgi apparatus is the packaging center of the cell in which it prepares the materials to be transported in the form of vesicles. The cytoskeleton is responsible for the shape of the cell. Centrioles aid in cell division. Ribosomes, non-membranous organelle, is responsible for protein synthesis. The rough endoplasmic reticulum synthesizes proteins due to the presence of ribosomes in it. The smooth endoplasmic reticulum synthesizes steroids and breaks down fats.
