Bio.1.1: Relationship Between Structures and Functions of Cells and Organelles
Bio 1.1.1: Structure and Function of Organelles In Eukaryotics
All of these organelles work together in the function of the cell:
Nucleus: Controls all the activities of the cell since it contains the genetic material of the cell.; Plant and Animal
Plasma Membrane: Keeps the organelles and intracellular fluid from.the surrounding extracellular environment; Animal
Cell Wall: Structural support and protection to the cell; Plant
Mitochondria: Acts as the digestive system in the cell; Plant and Animal
Vacuoles: Stores food and other nutrients; Plant
Chloroplasts: Produce glucose from carbon dioxide and water; Plant
Ribosomes: Where proteins are produced; Plant and Animal
Nucleolus: Non-membrane bound structure that contains proteins and nucleic acids found within the nucleus; Plant and Animal
Lysosome: Digests and recycles used cell components; Plant and Animal

Bio 1.1.2: Compare Prokaryotic and Eukaryotic Cells
Prokaryotic Cells- Do not have a nucleus, has one chromosome but not a true one they have plasmids, unicellular cell type though some bacteria are multicellular, no true membrane bound nucleus, Bacteria and Archaea are an example of prokaryotes, undirectional transfers of DNA, no lysosomes, no E.R., no mitochondria, no cytoskeleton, multiple proteins act together to fold and condense prokaryotic DNA, small ribosomes, no golgi apparatus, no chlorosplasts the chlorphyll is scattered throughout the cell, chemically complexed cell wall, and has vacuoles
Eukaryotic Cells- Has a nucleus, more than one chromosomes, usually multicellular cell type, present membrane bound nucleus, animals and plants are an example of eukaryotes, meiosis, has lysosomes, has E.R., has mitochondria, has cytoskeleton, wrap DNA around proteins, larger ribosomes, has golgi appratus, has chloroplasts in plants, has cell wall in plants, and has vacuoles

Bio 1.1.3 Instuctions in DNA Lead To Cell Differentiation
- During differentiation only specific parts of the DNA is activated; the activated parts determine the function and specialized structure of the cell
- All cells contain the same DNA, so that means all cells have the potential to become any type of cell; differentiation cannot be reversed
- Almost all of the cells of a multicellular organisim have the same chromosomes and DNA
- Different parts of the genetic instructions are used in different cells , influenced by the environment and the cell's past history
- Chemical signs can be released by one cell to influence the development and activity of another
- Embryonic cells that haven't differentiated are called embryonic stem cells
- Stem cells found in organisims are called adult stem cells
- Stem cells differentiate into specialized cells
