Skeleton & Body Movements Flashcards
Passive Transport
Requires NO ATP (Energy) objects wove down a concentration gradient (high to low)
A T P
Adenosine Triphosphate
Osmosis
movement of water from high concentration of water to an area of low concentration of water
HypERtonic solution (crenate)
a solution where there is L O W E R water concentration outside the cell
HyPOtonic Solution (lyse)
a solution where there is a H I G H E R water concentration outside the cell
Isotonic Solution
Equal concentration
Diffusion
movement of substance from a high concentration to an area of low concentration
Active Transport
Requiring ATP
Exocytosis
Taking things O U T of the cell (wastes/secretory products) -
Endocytosis
Bringing items I N S I D E the cell
Phagocytosis
“cell E A T I N G” reach out and surrounding an object - bringing into the cell
Pinocytosis
“cell D R I N K I N G” bringing small fluid into the cell
Cell Division
division of the cells from one parent cell to the 2 Daughter cells
Interphase
Cells Grow | DNA Replicates & Carries out regular cell function
G 1
Growth Phase - normal cell functions plus cell growth, organelle duplication, protein synthesis (8+ hours)
S (Synthesis Phase)
Synthesis Phase - DNA replication, synthesis of H I S T O N E S (6-8 Hours)
G 2
Growth Phase - protein & synthesis (2-5 Hours)
Mitosis
division of a single cell producing a pair of daughter cells
Prophase
Visible chromosomes/ condensing Nucleus present
Metaphase
chromosomes L I N E up in the middle of the cell Nucleus Gone
Anaphase
Chromosomes moving A W A Y to opposite sides of the cell
Telophase
chromosomes are at the opposite ends & create new Nuclei to make new cells
Cytokinesis
final separation into 2 cells by splitting the Cytoplasm
C E L L S
Cells are the structural and functional units of ALL living things
Plasma Membrane
outer layer of the cell (regulates what comes in & out)
Nucelus
(Middle Ball) control center of the cell
Nucleoli
Site of Ribisome production
Nuclear Envelope
outside covering of Nucleus
Nuclear Pores
Pores to allow passage to & from nucleus
