Term
MICROGRAPH
Definition
image produced by a microscope
Term

Definition
  • USES 2 LENSES
  • LIGHT BULB IN BASE SHINES LIGHT THROUGH THE SPECIMEN
  • KIND OF MICROSCOPE WE USE IN CLASS
  • OCULAR LENS OF 10x
  • 3 OBJECTIVE LENSES

 

Term
CELL THEORY
Definition

1 - ALL LIVING THINGS ARE MADE OF 1 OR MORE CELLS


2 - CELLS ARE THE BASIC UNITS OF STRUCTURE & FUNCTION IN ORGANSIMS


3 - ALL CELLS ARISE FROM EXISTING CELLS

Term

ANTON

VON LEEUWENHOEK

Definition
1675 DISCOVERED SINGLE CELLED ORGANISMS
Term
PROKARYOTES
Definition
  • SINGLE CELLED ORGANISN THAT LACKS A NUCLEUS & OTHER INTERNAL COMPARTMENTS
  • CANNOT CARRY OUT MANY SPECIALIZED FUNCTIONS
  • BACTERIA
  • SINGLE LOOP OF DNA IN THE CENTER


Term
CELL WALL
Definition

RIGID STRUCTURE THAT SURROUNDS THE CELL MEMBRANE & PROVIDES SUPPORT TO THE CELL; STRANDS OF POLYSACCHARIDES

  • BACTERIA
  • FUNGI
  • PLANTS

 

Term
MAGNIFICATION
Definition
QUALITY OF MAKING AN IMAGE APPEAR LARGER THAN ITS ACTUAL SIZE
Term
RESOLUTION
Definition
MEASURES THE CLARITY OF AN IMAGE; ELECTRON MICROSCOPES HAVE HIGHER MAGNIFYING & RESOLVING POWERS THAN LIGHT MICROSCOPES
Term
FLAGELLA
Definition
LONG HAIRLIKE (THREADLIKE) STRUCTURE THAT GROWS OUT OF A CELL & ENABLES THE CELL TO MOVE
Term
EUKARYOTE
Definition

CELL THAT HAS A NUCLEUS ENCLOSED MEMBRANE, MULTIPLE CHROMOSOMES & A MITOTIC CYCLE

  • ANIMALS
  • PLANTS
  • FUNGI
Term
NUCLEUS
Definition
MEMBRANE BOUND ORGANELLE THAT CONTAINS THE CELLS DNA & THAT HAS A ROLE IN PROCESSES SUCH AS GROWTH, METABOLISM & REPRODUCTION
Term
ORGANELLE
Definition
ONE OF THE SMALL BODIES THAT ARE FOUND IN THE CYTOPLASM OF A CELL & THAT ARE SPECIALIZED TO PERFORM A SPECIFIC FUNCTION
Term
CILIA
Definition
HAIRLIKE STRUCTURES ARRANGED IN TIGHTLY PACKED ROWS THAT PROJECT FROM THE SURFACE OF SOME CELLS
Term
CELL MEMBRANE
Definition
SEMI-PERMIABLE MEMBRANE; PHOSPHOLIPID LAYER THAT COVERS A CELL'S SURFACE & ACTS AS A BARRIER BETWEEN THE INSIDE OF A CELL & THE CELLS ENVIRONMENT
Term
CYTOPLASM
Definition
REGION OF THE CELL WITHIN THE MEMBRANE THAT INCLUDES THE FLUID, CYTOSKELTON & ALL OF THE ORGANELLES EXCEPT THE NUCLEUS
Term
CYTOSKELETON
Definition
PROVIDES INTERIOR FRAMEWORK; KEEPS MEMBRANE FROM COLLAPSING
Term
RIBOSOME
Definition
CELL ORGANELLE COMPOSED OF RNA & PROTEIN; SITE OF PROTEIN SYNTHESIS
Term
ROUGH (ER) ENDOPLASMIC RETICULUM
Definition
ER WITH RIBOSOMES ATTACHED; HELPS TRANSPORT PROTEINS MADE BY THE RIBOSOMES
Term
SMOOTH (ER) ENDOPLAMIC RETICULUM
Definition
MAKES LIPIDS & BREAKS DOWN TOXIC SUBSTANCES
Term
VESICLE
Definition
SMALL, MEMBRANE-BOUND SAC THAT TRANSPORTS SUBSTANCES IN CELLS
Term
GOLGI APPARATUS

CELL ORGANELLE THAT HELPS MAKE & PACKAGE MATERIALS TO BE TRANSPORTED OUT OF THE CELL
Term
LYSOSOMES
Definition
CELL ORGANELLE THAT CONTAINS DIGESTIVE ENZYMES; TRASHMEN  OF CELL
Term
MITOCHONDRIA
Definition
CELL ORGANELLE THAT IS SURRONDED BY 2 MEMBRANES & THAT IS THE SITE OF CELLULAR RESPIRATION WHICH PRODUCES ATP
Term
CHLOROPLASTS
Definition
ORGANELLE FOUND IN PLANT & ALGAE CELLS WHERE PHOTOSYNTHESIS OCCURS; USES LIGHT ENERGY TO MAKE CARBOHYDRATES FROM CO2 & H2O
Term
CENTRAL VACUOLE
Definition

LARGE MEMBRANE-BOUND SAC; STORES WATER & CAN CONTAIN IONS, NUTRIENTS & WASTES

  • WHEN FULL, CELL IS RIGID & PLANT STANDS UPRIGHT
