SECTION 2.1 Diffusion- is the movement of particles from an area where thier concentration is high to an are where thier concentration is low. Osmosis- the diffusion of water across a cell membrane Passive Transport- the diffusion of particles through protiens in the cell membrane from areas where the concentration of particles is high to areas where concentration of particles is low Active Transport- the movement of particles through protiens in the cell membrane against the directionof diffusion; requires cells to use energy Endocytosis- the proccess in which a cell membrane surrounds a particle and encloses it is a vesicle to bring it into the cell Exocytosis- the proccess used to remove large particles from a cell during exocytosis a vesicle containing the particles uses with the cell membrane

SECTION 2.2 Photosynthesis- The process of capturing light, energy and changing it into food. Cellular respiration- The process of making and storing energy using oxygen. Fermentation- The process of making and storing energy without using oxygen.

SECTION 2.3 **Cell Cycle: ** The life cycle of a cell. **Chromosome: ** The DNA of a cell organized into structures. **Binary Fission: ** Splitting into two parts. **Homologous: **Pairs made up of similar chromosomes. **Chromatids: **The two copies of duplicated chromosomes. **Centromere: ** Chromatids held together at a region. **Mitosis: ** The complicated process of chromosome separation. **Cytokenisis: ** Once mitosis is completed the cytoplasm splits in two.
