Nucleus
Question: Fat cell Answer: Cell that stores nutrients Question: Macrophage
Answer: cell extends long psedopods to crawl tissue to reach infection sites. the many lysosome within the cell digest the infectious microorganisms it takes up Question: Answer: Cell that fights
Question: Nerve cell Answer: ER, Nucleus
Question: cellAnswer: Cell that gathers and controls body
functions
Question: Answer: Question: Cell of Answer: Question: SpermAnswer: , Flagellum
Question: SolutionAnswer: homogeneous mixture of two or more Question: SolventAnswer: dissolving medium; typically water in the Question: fluidAnswer: and cytosol Question: Interstitial Answer: fluid on the exterior of the Question: PermeabilityAnswer: The plasma membrane allows some materials to pass while excluding .
This permeability influences movement both into and out of the cell.
Question: Membrane Transport: Two basic methods of Answer: processes & Active processes
Question: Passive Answer: No is required Question: Active Answer: Cell must provide metabolic (ATP) Question: Answer: Particles tend to distribute themselves evenly within a solution
Movement is from high concentration to low , or down a concentration gradient
Question: Passive Types of diffusion
Answer: Simple diffusion, Osmosis, Facilitated diffusion, Processes, Active Processes,
Question: Simple Answer: An unassisted process
Solutes are -soluble materials or small enough to pass through membrane pores
Question: Answer: simple diffusion of water
Highly polar water molecules cross the plasma membrane through aquaporins Question: diffusion
Answer: Substances require a protein carrier for passive lipid-insoluble and large substances Question: ProcessesAnswer: Water and solutes are forced through a membrane by , or hydrostatic pressure
A pressure gradient must exist
Solute-containing fluid is pushed from a high-pressure area to a lower pressure area
Question: Active : Substances are transported that are unable to pass by diffusionAnswer: Substances may be too lg,
Substances may not be able to in the fat core of the membrane, Substances may have to move against a concentration gradient
Question: Active Processes, Two forms of active transport
Answer: transport (solute pumping)
Vesicular transport
Exocytosis
Endocytosis
Phagocytosis
Pinocytosis
Question: ProcessesAnswer: ATP is used for Question: Epithelium that consist of layers of a cellAnswer: Question: The organelle that consist enzymes produced by and packaged by the golgi apparatus is theAnswer: Question: the portion of the cells life cycle that does not cell division is known as Answer: Interphase Question: Which type of tissue electrochemical impulsesAnswer: Tissue Question: the molecule that carries an amino acid to the for incorporation into a protein isAnswer: RNA (tRNA) Question: Fat is best as Answer: tissue Question: bonds withAnswer: Question: Glands, such as the thyroid, that secrete their products directly into the rather than through ducts are classified as Answer: Endocrine Question: bonds withAnswer: Cytosine Question: The type of muscle found in the walls of organs, such as the stomach and the walls of blood vessels isAnswer: Smooth Question: A single layer of flatten cell best be described asAnswer: Squamous Question: Type of active process in the cell secrets vesiclesAnswer: Question: Organelle that captures to produce ATPAnswer: MItochondria Question: The type of muscle found in the heart movement is involuntary and cells possess Answer: Question: Organelle that package substances for from cellAnswer: apparatus Question: Aide SynthesisAnswer: Question: Type of process in which water is moved through aquapororinsAnswer: Question: list the 4 major tissue Answer: Epithelial, Connective, and Nervous tissue Question: the phases of in orderAnswer: Prophase, , Anaphase and Telophase Question: Rough Answer: Has all material for building in the cell and assembles it it is considered the factory of the cell Question: Answer: elaborated network of protein structures extends throughout the cytoplasm; acts like bones and for cell shape and support of organelles |
