1
INTRODUCTORY INFORMATION CELL STRUCTURE & FUNCTION
2
HE MADE A “MICROSCOPE” A SINGLE POWERFUL LENS LOOKED AT A DROP OF POND WATER AND SAW “ANIMALCULES” (PROTISTS)
3
CREDITED WITH DISCOVERING AND NAMING THE CELL USED ONE OF THE FIRST LIGHT MICROSCOPES VIEWED A SLICE OF CORK – SAW THE CELL WALLS OF CORK TISSUE; ITS STRUCTURE REMINDED HIM OF A MONASTERY’S TINY ROOMS CALLED CELLS
4
I could exceedingly plainly perceive it to be all perforated and porous, much like a Honey-comb, but that the pores of it were not regular.... these pores, or cells,... were indeed the first microscopical pores I ever saw, and perhaps, that were ever seen, for I had not met with any Writer or Person, that had made any mention of them before this...
5
GERMAN BOTANIST CONCLUDED THAT ALL PLANTS ARE MADE OF CELLS
6
GERMAN ZOOLOGIST CONCLUDED THAT ALL ANIMALS ARE MADE OF CELLS
7
GERMAN PHYSICIAN STUDIED CELL REPRODUCTION CONCLUDED “WHERE A CELL EXISTS, THERE MUST HAVE BEEN A PREEXISTING CELL”
8
ALL LIVING THINGS ARE MADE OF CELLS. CELLS ARE THE BASIC UNITS OF STRUCTURE AND FUNCTION IN LIVING THINGS NEW CELLS ARE PRODUCED FROM EXISTING CELLS
9
PROKARYOTIC – “NO TRUE NUCLEUS” OR CELLS THAT DO NOT HAVE MEMBRANE-BOUND ORGANELLES EUKARYOTIC – “TRUE NUCLEUS” OR CELLS THAT DO CONTAIN MEMBRANE-BOUND ORGANELLES
10
ORGANELLES ARE: CELL WALL CELL MEMBRANE RIBOSOMES CYTOPLASM
11
THE ONLY PROKARYOTIC ORGANISMS ARE THE BACTERIA REPRODUCE BY BINARY FISSION REPRODUCE EXPONENTIALLY REVIEW QUESTION: WHERE IS DNA FOUND IN A BACTERIAL CELL?
12
CONTAIN MEMBRANE-BOUND ORGANELLES SPECIALIZED STRUCTURES THAT PERFORM SPECIFIC CELLULAR FUNCTIONS PLANTS, ANIMALS, FUNGI AND PROTISTS ARE ALL EUKARYOTES
13
ALL CELLS CONTAIN DNA – A NUCLEIC ACID; DNA IS NOT AN ORGANELLE; ALL CELLS HAVE A CELL MEMBRANE; NOT ALL CELLS HAVE A CELL WALL; ANIMAL CELLS NEVER HAVE A CELL WALL;
14
CHAPTER 7 PAGE 169 SECTION 7-2 PAGES 173 – 183 MAKE A TWO-COLUMN CHART OF THE CELL ORGANELLES, GIVING THE ORGANELLE NAME AND FUNCTION
