1. Cell Transport

1.1. Small Particles

1.1.1. Passive Transport=No cell energy, with gradient Diffusion=Movement from area of high concentration to low concentration Osmosis=Diffusion of water across a membrane

1.1.2. Active Transport=Uses cell energy, against gradient

1.2. Large Particles

1.2.1. Active Transport Endocytosis/Enter Exocytosis/Exit

2. Cell Cycle

2.1. Interphase

2.1.1. G1 Phase Cell growth, signal to divide occurs, a cell spends most of its lifetime here

2.1.2. S Phase DNA copied, synthesis

2.1.3. G2 Phase Cell growth, organelles copied

2.2. M Phase

2.2.1. Mitosis Prophase Chromosomes become visible. Chromosomes made up of sister chromatids held together by a centromere. Centrioles move toward opposite poles. Spindle fibers start to form. Metaphase Centrioles are on opposite sides. Spindle fibers stretch across the cell. Chromosomes line up along the center of the cell. Spindle fibers attach to centromeres. Anaphase Sister chromatids separate. Spindle fibers shorten. One chromatid moves to left pole. The other chromatid moves to the right pole. Telophase Membrane pinches to form two daughter cells. Half of cytoplasm and organelles go to one daughter cell. Half of cytoplasm and organells go to the other daughter cell.

2.2.2. Cytokinesis

3. Cell Energy

3.1. Photosynthesis

3.1.1. Carbon Dioxide+Water+Light Energy--Simple Sugar+Oxygen (6CO2+6H2O+Energy--C6H12O6+6O2) Takes place in chloroplast

3.2. Oxidation

3.2.1. Simple Sugar+Oxygen--Carbon Dioxide+Water+Light Energy (C6H12O6+6O2--6CO2+6H2O+Energy) Takes place in mitochondria

3.3. Most of life's energy is in stored in the carbon to carbon links! Oxygen breaks the c to c links and releases energy. The more c to c links gets broken, the more energy the cell/ molecules get. This is why cells need extra oxygen when breaking down molecules.
