1. Cell Transport

1.1. Small Particles

1.1.1. Passive Transport=No cell energy, with gradient

1.1.1.1. Diffusion=Movement from area of high concentration to low concentration

1.1.1.1.1. 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

1.2.1.1. Endocytosis/Enter

1.2.1.2. Exocytosis/Exit

2. Cell Cycle

2.1. Interphase

2.1.1. G1 Phase

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

2.1.2. S Phase

2.1.2.1. DNA copied, synthesis

2.1.3. G2 Phase

2.1.3.1. Cell growth, organelles copied

2.2. M Phase

2.2.1. Mitosis

2.2.1.1. Prophase

2.2.1.1.1. Chromosomes become visible. Chromosomes made up of sister chromatids held together by a centromere. Centrioles move toward opposite poles. Spindle fibers start to form.

2.2.1.2. Metaphase

2.2.1.2.1. 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.

2.2.1.3. Anaphase

2.2.1.3.1. Sister chromatids separate. Spindle fibers shorten. One chromatid moves to left pole. The other chromatid moves to the right pole.

2.2.1.4. Telophase

2.2.1.4.1. 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)

3.1.1.1. Takes place in chloroplast

3.2. Oxidation

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

3.2.1.1. 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.
