1BUILDING BLOCKS OF LIFEBY SHAAKIRA ABDIRAHMAN
2WHEN AND WHO MADE THE FIRST MICROSCOPE?ZACHARIAS JANSSEN, AROUND 1950
3HOW DID HE MAKE THE FIRST MICROSCOPE ?HE WAS EXPERIMENTING WITH LENSES AND PLACED TWO LENSES INSIDE A TUBE.
4HOW 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
5WHO WAS ANTONIE VAN LEEUWENHOEK?HE WAS AN EXPERT MICROSCOPE BUILDER. HE BUILT MICROSCOPES THAT WERE ABLE TO MAGNIFY UP TO X250.
6HOW 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
7WHAT DID HE CALL MICRO-ORGANISMS?
8WHO DISCOVERED THAT PLANT CELLS WERE NOT JUST EMPTY BOXES?SCOTTISH BOTANIST ROBERT BROWN, HE DISCOVERED THEY HAD EVEN SMALLER STRUCTURES INSIDE THEM.
9WHAT DOES THE CELL THEORY EXPLAIN?THE CELL THEORY EXPLAINS THE RELATIONSHIP BETWEEN CELLS AND LIVING THINGS
10WHAT 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
11WHAT ARE ORGANELLES?LITTLE ORGANS INSIDE CELLS
12NAME SOME ORGANELLES THAT ARE ONLY SEEN WITH A ELECTRONIC MICROSCOPE.1. MITOCHONDRIA
2. LYSOSOMES
3. ENDOPLASMIC RETICULUM
13MITOCHONDRIATHE POWERHOUSES OF THE CELL THAT RELEASE ENERGY FROM FOOD
14LYSOSOMESTHE GARBAGE DISPOSAL UNITS THAT GET RID OF WASTES FROM THE CELL
15ENDOPLASMIC RETICULUMFORMS PATHWAYS THAT ALLOW MATERIALS TO MOVE QUICKLY AND EASILY THROUGH THE CELL
16NUCLEUSTHE CONTROL CENTER OF A CELL
17CYTOPLASMCYTOPLASM IS A WATERY, JELLY-LIKE MIXTURE THAT CONTAINS MANY SMALLER PARTS, WHERE THE WORK OF THE CECLL TAKES PLACE
18CELL MEMBRANETHE 'SKIN' THAT HOLDS THE CELL TOGETHER; IT CONTROLS WHAT COMES INTO AND OUT OF THE CELL
19VACUOLEA 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
20CELL WALLA RIGID LAYER ON THE OUTSIDE OF A PLANT CELL; PROVIDES THE SKELETON OF A PLANT
21CHLOROPLASTAN ORGANELLE WITHIN THE CELL WHERE PHOTOSYNTHESIS TAKES PLACE
22RIBOSOMESSTRUCTURE THAT PRODUCE PROTEIN
23PHOTOSYENTHESISTHE PROCESS USED BY PLANTS TO MAKE FOOD FROM WATER AND CARBON DIOXIDE USING ANY ENERGY FROM THE SUN
24MITOSISCELL DIVISION THAT PRODUCES TWO IDENTICAL CELLS
25WHY IS MITOSIS IMPORTANT?FOR REPAIRING DAMAGED CELLS AND REPRODUCING
26HOW 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
27DESCRIBES THE CELLS OF A FUNGI?THEY HAVE THE SAME STRUCTURE OF AN ANIMAL CELL AND A CELL WALL LIKE A PLANT CELL.
