  2. Plasma membrane Arrange to form Is a type of phospholipid molecule Working together make to form describes Surround contents of Covalent bond cell Fluid mosaic model Combine using Cell nucleus containing Talks about Atom prokaryote Cell theory organelle With opposite charges form Not found in Directs processes in Located in explains Are called Ionic bond Atomic nucleus organization eukaryote

  3. Definitions • Atom – smallest particle of an element that has the characteristics of that element; basic building block of all matter. • Atomic nucleus- positively charged center of an atom composed of neutrons and positively charged protons, and surrounded by negatively charged electrons. • Covalent bond - chemical bond formed when two atoms share electrons. • Ionic bond – chemical bond formed by the attractive forces between two ions of opposite charge. • Molecule – Group of atoms held together by covalent bonds. • Organization – orderly structure of cells in an organism. • Cell – basic unit of all organisms, all living things are composed of cells. • Cell theory – the theory that (1) all organisms are composed of one or more cells, (2) the cell is the basic unit of structure and organization of organisms, (3) al cells come from preexisting cells. • Organelle – membrane bound structures with particular functions within eukaryotic cells. • Prokaryote – unicellular organisms such as bacteria that lack membrane bound organelles. • Eukaryote – unicellular or multicellular organisms that contain a true cell nucleus and membrane bound organelles. • Cell nucleus – the central organelle in eukaryotic cells that manages cell functions and contains DNA. • Fluid mosaic model – structural model of the plasma membrane where molecules are free to move sideways within a lipid bilayer. • Phospholipid – lipids with an attached phosphate group; plasma membranes are composed of phospholipid bilayer with embedded proteins. • Plasma membrane – flexible boundary between the cell and its environment; allows materials such as water and nutrients to enter and waste products to leave.

  4. Connections explainedDirections: use the concept map to fill in the blanks of the explanations. • The positively charged ______________which is made up of subatomic particles called protons (which have a positive charge) and neutrons (which have no charge) is located in the center of an _______. • An ______can combine with other atoms using ______________to form ____________. • __________of different types with different functions working together make up living ____. • A _______containing __________sare called ____________s. • A _______________is an organelle that directs cell processes in an ____________cell. • ___________are not found in ______________cells. • A _____________is a type of ___________which because of its hydrophilic and hydrophobic parts will arrange to form lipid bilayer forming a __________________. • The ____________________describes the parts and movement of the ________________. • The ________________which is selectivity permeable surrounds the contents of a ___to help maintain homeostasis. • The ___________talks about ____sbeing the central unit of life and how all cells must come from pre-existing cells therefore explains the hierarchal _____________of living things. • ______that gain or lose electrons turn into positive or negative ions which have opposite charges that attract each other to form ____________.

  5. Picture choices explainedDirections: Fill in the blanks and use the explanation for using each picture to figure out and match the picture (slides 9 through 12) in the VTN. • For _____________I chose a picture showing a pulled out close up view of the atomic core composed of protons and neutrons. This is a picture representation of the definition of the term. • For _____I chose a picture showing a model of a Beryllium ____with two protons and two neutrons in its atomic nucleus and 2 electrons orbiting around the nucleus. This is computer generated 3D version of the Bohr model which is what I think of when I hear or read the term. The picture matches the definition of the term. • For ____________I chose a picture of methane molecule sharing electrons between the four hydrogen atoms and the carbon atom in order to fill the valence shells. This picture demonstrates an example of the term. • For _________I chose a picture of a water molecule sharing valence electrons between the oxygen atom and the two hydrogen atoms. This picture is a common representation of the term.

  6. I think of the compound sodium chloride salt when I think of _________so chose a picture showing sodium cations bonding with chlorine anions. • For ___________ I chose a picture showing the most common features of most prokaryotes which does not include organelles but does include characteristics such as a plasma membrane, cell wall, cytosol (cytoplasm), long circular DNA located in the central nucleoid region, ribosomes, and small easily transferable pieces of DNA called plasmids. • When I think of the term ____ the typical animal type pops into my head so I picked a picture of one which a person knows to be the animal type due to the fact it has a cell nucleus, mitochondria, lysosomes, Golgi apparatus, rough and smooth endoplasmic reticulum and does not contain a cell wall or chloroplasts. • For ___________I picked a picture depicting the features of one which include a porous double plasma membrane, DNA packaged in chromosomes, chromatin, and a central dense region called the nucleolus. • For _________ I chose a picker of a mitochondria because is one of the main types I think about when I think the term because it is the “power house” of the cell found in every type of eukaryote.

  7. When I think of __________ other than an animal cell I think of a plant cell because it contains all the other organelles and animal cell does plus chloroplasts which it uses to convert light energy into stored chemical energy which complex life on our planet depends on. • When I think about a ____________ the type of picture I chose comes to mind showing two long hydrophobic fatty acid tails connected via a triglyceride to a polar hydrophilic phosphate group. • I chose the picture for _______________because it clearly shows a phospholipid bilayer (separated at one end to show the hydrophobic middle part along with embedded proteins). • For __________________I chose a picture of a plasma membrane showing some trans-membrane proteins anchored to internal scaffolding and glycoproteins on the cell surface. The picture shows the plasma membrane in a wave which makes me think of it flowing. • For __________I combined four pictures to represent the 3 statements of it. A single cell prokaryote, a colony of single celled eukaryotes, a close up view of a multicellular eukaryote, and a cell in the process of dividing into two daughter cells. This is a picture representation of 1. The cell is the basic unit of life. 2. All living thins are made up of one or more cells. And 3. All cells come from pre-existing cells.

  8. For ______________ I chose a picture that came the closest to representing the term as I think about it in the context of biology. An atom making a molecule, which goes on to make cells, cells make tissue, tissue make organs, organs make organ systems, organ systems make organisms, organisms make populations, populations make communities, and the communities combine to make up the whole ecosystem.
