Term
CELL
Definition
COLLECTION OF LIVING MATTER ENCLOSED BY A BARRIER THAT SEPARATES THE CELL FROM ITS SURROUNDINGS; BASIC UNIT OF ALL LIFE FORMS
Term
CELL THEORY
Definition
A FUNDAMENTAL CONCEPT OF BIOLOGY
Term
NUCLEUS
Definition
A LARGE MEMBRANE-ENCLOSED STRUCTURE THAT CONTAINS THE CELL'S GENERIC MATERIAL IN THE FORM OF DNA

THREADLIKE STRUCTURES CONTAIN THE GENETIC INFORMATION THAT IS PASSED FROM ONE GENERATION OF CELLS TO THE NEXT
Term
NUCLEOLUS
Definition
WHERE THE ASSEMBLY OF RIBOSOMES BEGINS
Term
NUCLEOLUS
Definition
WHERE THE ASSEMBLY OF RIBOSOMES BEGINS
Term
RIBOSOMES
Definition
SMALL PARTICLES OF RNA AND PROTEIN FOUND THROUGHOUT THE CYTOPLASM
Term
ENDOPLASMIC RETICULUM
Definition
THE SITE WHERE LIPIDS COMPONENTS OF THE CELL MEMBRANE ARE ASSEMBLED,ALONG WITH PROTEINS AND OTHER MATERIALS THAT ARE EXPORTED FROM THE CELL
Term
CHROPLAST
Definition
CHROPLAST ARE ORGANELLS THAT CAPTURE THE ENERGY FORM SUNLIGHT AND CONVERT IT INTO CHEMICAL ENERGY IN A PROCESS CALLED PHOTOSYNTHESIS
Term
CYTOSKELETON
Definition
THAT HELPS SUPPORT THE CELL
Term
CENTRIOLES
Definition
LOCATED NEAR THE NECLEUS AND HELP TO ORGANIZE CELL DIVISION
Term
CELL MEMBRANE
Definition
ALL SELLS ARE SURROUNDED BY A THIN FLEXIBLE BARRIER
Term
CELL WALL
Definition
MANY CELLS ALSO PRODUCE A STRONG SUPPORTING LAYER AROUND THE MEMBRANE
Term
LIPID BILAYER
Definition
THE COMPOSITION OF NEARLY ALL CELL MEMBERS IS A DOUBLE-LAYERED SHEET
Term
CONCENTRATION
Definition
A SOLUTION IS THE MASS OF SOLUTE IN A GIVEN VOLUME OF SOLUTION, OR MASS/VOLUME.
Term
DIFFUSION
Definition
THE PATTICLES TEND TO MOVE FROM AN AREA WHERE THEY ARE LESS CONCENTRATED
Term
EQUILIBRIUM
Definition
WHEN THE CONCENTRATION OF THE SOLUTE IS THE SAME THROUGHOUT A SYSTEM
Term
OSMOSIS
Definition
THE DIFFUSION OF WATER THROUGH A SELECTIVELY PERMEABLE MEMBRANE
Term
ISTONIC
Definition
THE TWO SOLUTIONS WILL BE THE SAME STRENGTH
Term
HYPERTONIC
Definition
"ABOVE STRENGHT" AS COMPARED TO THE DILUTE SUGAR SOLUTION
Term
HYPOTONIC
Definition
"BELOW STRENGTH"
Term
FACILITATED DIFFUSION
Definition
MOLECULES THAT CANNOT DIFFUSE ACROSS THE CELL MEMBRANE'S LIPID BILAYER ON THEIR OWN MOVE THROUGH PROTIEN CHANNELS
Term
ACTIVE TRANSPORT
Definition
CELLS SOMETIMES MUST MOVE MATERIALS IN THE OPPOSITE DIRECTION--AGAINST A CONCENTRATION DIFFERENCE
Term
ENDOCYTOSIS
Definition
THE PROCESS OF TAKING MATERIAL INTO THE CELL BY MEANSOF INFOLDINGS, OR POCKETS,OF THE CELL MEMBRANE
Term
PHAGOCYTOSIS
Definition
EXTENSIONS OF CYTOPLASM SURROUND A PARTICLE AND PACKAGE IT WITHIN A FOOD VACULE
Term
EXOCYTOSIS
Definition
THE MEMBRANE OF THE CELL VALUOLE SURROUNDING THE MATERIAL FUSES WITH THE CELL MEMBRANE,FORCING CONTENTS OUT OF THE CELL
Term
CELL SPECIALIZATION
Definition
CELLS THROUGH OUT AN ORGANISM CAN DEVELOPE IN DIFFRENT WAYS TO PREFORM DIFFRENT TASKS
Term
TISSUE
Definition
A GROUP OF SIMILAR CELLS THAT PREFORM A PARTICULAR FUNCTION
Term
ORGAN
Definition
MANY GROUPS OF TISSUES WORK TOGETHER
Term
ORGAN SYSTEM
Definition
A GROUP THAT WORK TOGETHER TO PERFORM A SPECIFIC FUNCTION
