L i f e B e g i n s W i t h C e l l s If the nucleus were the si ze of a penny, the cell would be the size of a football field. The Cell Theory 1. A l l l i v i n g t h i n g s are made of cells. 2. C e l l s a r e t h e b a s i c units of life. 3. C e l l s c o m e o n l y from other cells. The Basic Parts nucleus cytoplasm cell membrane s Nucleus and DNA Membrane Structure C Cell Introduction End Cell Cycle Mitosis DNA is duplicated then divided into two identical sets. Interphase normal cell activity Prophase chromatin condenses i n to chromosomes nuclear membrane disappears Metaphase chromosomes line up at the cell equator Anaphase chromosomes move to opposite ends of the cell Telophase chromosomes disappear nuclear membrane reforms cell begins to divide End Cell Cycle Cellular Respiration Remember! Glucose stores the sun’s energy in chemical form. Remember! Adenosine TriphosphateATP - is the molecule most organisms can actually use for energy. Remember! Respiration requires oxygen to efficiently change glucose i n t o A T P. End Cellular Respiration
