LEVELS OF ORGANISATION Flashcards
WHAT ARE LIVING ORGANISMS MADE UP OF
CELLS
WHAT ARE CELLS
THEY ARE LIKE TINY BUILDING BLOCK OF AN ORGANISM
SOME ORGANISMS ARE (…) THEY CONTAIN LOTS OF CELLS WHICH NEED SOME FORM OF ORGANISATION
MULTICELLULAR
ORGANISMS THAT ARE NOT MULTICELLULAR ARE…
SINGLE CELL
CELLS CAN BE (…) OR (…)
EUKARYOTIC OR PROKARYOTIC
WHAT ARE EUKARYOTIC CELLS
THEY ARE COMPLEX AND THEY INCLUDE ALL ANIMAL AND PLANT CELLS
WHAT ARE PROKARYOTIC CELLS
SMALLER AND SIMPLER CELLS (BACTERIA)
WHAT ARE ORGANELLES
THEY ARE TINY STRUCTURES WITHIN CELLS (CAN ONLY BE SEEN USING A POWERFUL MICROSCOPE)
WHICH ARE THE ORGANELLES FOUND IN A TYPICAL ANIMAL CELL
NUCLEUS
CELL MEMBRANE
CYTOPLASM
MITOCHONDRIA
RIBOSOMES
WHAT IS A NUCLEUS
AN ORGANELLE WHICH CONTAINS THE GENETIC MATERIAL THAT CONTROLS THE CELL’S ACTIVITY
WHAT IS THE NUCLEUS SURROUNDED BY
ITS OWN MEMBRANE
WHAT IS A CELL MEMBRANE
THIS MEMBRANE FORMS THE OUTER SURFACE OF THE CELL AND CONTROLS THE SUBSTANCES THAT GO IN AND OUT
WHAT IS A CYTOPLASM
A GEL-LIKE SUBSTANCE WHERE MIST OF THE CELLS CHEMICAL REACTIONS HAPPEN.
WHAT DOES A CYTOPLASM CONTAIN
AN ENZYME WHICH CONTROL THESE REACTIONS
WHAT ARE A MITOCHONDRIA
SMALL ORGANELLES WHERE MOST OF THE REACTIONS FOR AEROBIC RESPIRATION TAKE PLACE
WHAT ARE RIBOSOMES
SMALL ORGANELLES WHERE PROTEIN ARE MADE IN THE CELL
WHAT OTHER ORGANELLES DOES PLANTS HAVE APPART FROM THE ANIMAL ONES
CHLOROPLASTS
CELL WALL
VACUOLE
WHAT ARE CHLOROPLASTS
CHLOROPLASTS CONTAIN A GREEN SUBSTANCE CALLED CHLOROPHYLL WHICH IS USED IN PHOTOSYNTHESIS
WHAT IS A CELL WALL
A RIGID STRUCTURE MADE OF CELLULOSE, WHICH SURROUNDS THE CELL MEMBRANE.
WHAT DOES A CELL WALL DO
IT SUPPORTS THE CELL AND STRENFTHENS IT
WHAT IS A VACUOLE
A LARGE ORGANELLE THAR CONTAINS CELL SAP (A WEAK SOLUTION OF SUGARS AND SALTS)
WHAT DOES A VACUOLE DO FOR THE CELL
IT HELPS TO SUPPORT THE CELL
WHAT IS A TISSUE
A TISSUE IS A GROUP OF SIMILAR CELLS THAT WORK TOGETHER TO CARRY OUT A PARTICULAR FUNCTION
WHAT DOES THE PLANT (XYLEM TISSUE) DOESS
IT TRANSPORTS WATER AND MINERALS
WHAT CAN A TISSUE CONTAIN
MORE THAN ONE CELL TYPE
WHAT IS AN ORGAN
A GROUP OF DIFFERENT TISSUES THAT WORK TOGETHER TO PERFORM A FUNCTION
ORGANS WORK TOGETHER TO FORM (…)
ORGANS SYSTEMS
WHAT DOES ORGANS SYSTEMS DO
EACH SYSTEM DOES A DIFFERENT JOB
FOR EXAMPLE: IN MAMMALS THE DIGESTIVE SYSTEM IS MADE UP OF ORGANS INCLUDING THE STOMACH, INTESTINES, PANCREAS AND LIVER
