CELL ANALOGY THE ANIMAL CELL IS BEING COMPARED TO A FOOTBALL TEAM. BY: MYA FREAKIN BROWN AND CALEB FREAKIN MILLER ANIMAL CELL=FOOTBALL TEAM A CELL IS LIKENED TO A FOOTBALL TEAM BECAUSE‚ LIKE A CELL‚ A FOOTBALL TEAM HAS MANY PARTS TO IT WITH DIFFERENT FUNCTIONS. CELL MEMBRANE=OFFENSIVE LINE THE CELL MEMBRANE IS A SELECTIVE BARRIER FOR THE CELL. IT DETERMINES WHAT CAN ENTER OR LEAVE THE CELL‚ SO IT PROTECTS THE CELL FROM ITS SURROUNDINGS.

History of Cell Theory As we all probably know today‚ every single living being is made up by cells the building blocks of life. As much as we would like to take this fact for granted‚ we cannot help but acknowledge and remember the works and discoveries of earlier scientists which all contributed to our today’s understanding of the cell theory. The cell theory being; all living things are composed of one or more cells‚ cells are organisms’ basic units of structure and function‚ and cells only come

Cell division consists of two processes: mitosis and cytokinesis. Mitosis— division of the nucleus and its chromosomes— is divided into five phases:prophase‚ prometaphase‚ metaphase‚ anaphase‚ and telophase. Mitosis is followed by cytokinesis‚ when the cytoplasm splits to form two separate daughter cells. The cytoplasm of a cell in late interphase contains two centrosomes‚ each of which may contain a pair of centrioles. In the nucleus‚ the chromosomeshave been replicated during S phase‚ but are

The Cell Cycle Brittany Jameson Vista College Abstract The cell cycle is made up of five steps. These steps are interphase‚ mitosis‚ cytoplasmic division‚ cell differentiation‚ and cell death. During mitosis there is a series of four stages. The Cell Cycle To start the cell cycle the cells first go through a step called interphase. During this step the cell grows and synthesizes new molecules and organelles. In the S phase the DNA of the cell is replicated in preparation for cell division

The nucleus acts as the control center for a cell because it contains the genes‚ which control cellular structure and most cellular activities The cell is the basic‚ living
