| BUILDING BLOCKS OF LIFE | BY SHAAKIRA ABDIRAHMAN |
| WHEN AND WHO MADE THE FIRST MICROSCOPE? | ZACHARIAS JANSSEN, AROUND 1950 |
| HOW DID HE MAKE THE FIRST MICROSCOPE ? | HE WAS EXPERIMENTING WITH LENSES AND PLACED TWO LENSES INSIDE A TUBE. |
| HOW DID ROBERT HOOKE DISCOVER CELLS? | HE WAS USING A MICROSCOPE TO INVESTIGATE A CORK WHEN HE SAW THAT THE THIN SLICES OF CORK RESEMBLED HONEYCOMB AND CONTAINED LITTLE BOXES OR CELLS |
| WHO WAS ANTONIE VAN LEEUWENHOEK? | HE WAS AN EXPERT MICROSCOPE BUILDER. HE BUILT MICROSCOPES THAT WERE ABLE TO MAGNIFY UP TO X250. |
| HOW DID HE DISCOVER MIRO-ORGANISMS? | A FEW YEARS AFTER HOOKE'S DISCOVERY, HE USED ONE OF HIS OWN MICROSCOPES TO LOOK AT POND WATER. WHAT HE WAS SEEING WERE TINY, SINGLE-CELLED LIVING THINGS |
| WHAT DID HE CALL MICRO-ORGANISMS? | |
| WHO DISCOVERED THAT PLANT CELLS WERE NOT JUST EMPTY BOXES? | SCOTTISH BOTANIST ROBERT BROWN, HE DISCOVERED THEY HAD EVEN SMALLER STRUCTURES INSIDE THEM. |
| WHAT DOES THE CELL THEORY EXPLAIN? | THE CELL THEORY EXPLAINS THE RELATIONSHIP BETWEEN CELLS AND LIVING THINGS |
| WHAT IS THE RELATIONSHIP BETWEEN CELLS AND LIVING THINGS? | 1. ALL LIVING THINGS ARE MADE UP OF ONE OR MORE CELLS 2. CELLS ARE THE BASIC BUILDING BLOCKS OF ALL LIVING THINGS 3. NEW CELLS ARE PRODUCED FROM EXISTING CELLS |
| WHAT ARE ORGANELLES? | LITTLE ORGANS INSIDE CELLS |
| NAME SOME ORGANELLES THAT ARE ONLY SEEN WITH A ELECTRONIC MICROSCOPE. | 1. MITOCHONDRIA 2. LYSOSOMES 3. ENDOPLASMIC RETICULUM |
| MITOCHONDRIA | THE POWERHOUSES OF THE CELL THAT RELEASE ENERGY FROM FOOD |
| LYSOSOMES | THE GARBAGE DISPOSAL UNITS THAT GET RID OF WASTES FROM THE CELL |
| ENDOPLASMIC RETICULUM | FORMS PATHWAYS THAT ALLOW MATERIALS TO MOVE QUICKLY AND EASILY THROUGH THE CELL |
| NUCLEUS | THE CONTROL CENTER OF A CELL |
| CYTOPLASM | CYTOPLASM IS A WATERY, JELLY-LIKE MIXTURE THAT CONTAINS MANY SMALLER PARTS, WHERE THE WORK OF THE CECLL TAKES PLACE |
| CELL MEMBRANE | THE 'SKIN' THAT HOLDS THE CELL TOGETHER; IT CONTROLS WHAT COMES INTO AND OUT OF THE CELL |
| VACUOLE | A SMALL STRUCTURE IN THE ANIMAL CELLS THAT MAY CONTAIN WASTE OR CHEMICALS, OR A LARGE SAP-FILLED STRUCTURE IN PLANT CELLS THAT STORES WATER, WASTE AND NUTRIENTS |
| CELL WALL | A RIGID LAYER ON THE OUTSIDE OF A PLANT CELL; PROVIDES THE SKELETON OF A PLANT |
| CHLOROPLAST | AN ORGANELLE WITHIN THE CELL WHERE PHOTOSYNTHESIS TAKES PLACE |
| RIBOSOMES | STRUCTURE THAT PRODUCE PROTEIN |
| PHOTOSYENTHESIS | THE PROCESS USED BY PLANTS TO MAKE FOOD FROM WATER AND CARBON DIOXIDE USING ANY ENERGY FROM THE SUN |
| MITOSIS | CELL DIVISION THAT PRODUCES TWO IDENTICAL CELLS |
| WHY IS MITOSIS IMPORTANT? | FOR REPAIRING DAMAGED CELLS AND REPRODUCING |
| HOW DOES FUNGI OBTAIN THEIR OWN FOOD? | THEY PRODUCE AND RELEASE CHEMICALS THAT DIGEST THE MATERIAL THEY ARE GROWING ON. ABSORBS THE DIGESTED MATERIAL INTO THEIR CELLS |
| DESCRIBES THE CELLS OF A FUNGI? | THEY HAVE THE SAME STRUCTURE OF AN ANIMAL CELL AND A CELL WALL LIKE A PLANT CELL. |
