                                         SCIENCE – THE CELL
     What are the processes of photosynthesis and respiration and how are they related to one another?
 (i.e. The WHO, WHAT, HOW, WHY, WHERE, and WHEN of CELLS “CAPTURING”, “STORING”
                                       AND “USING” ENERGY?)
                                                                                Cell Energy Notes

INTRODUCTION: The cell is the building block of _________________. Hence, the cell is ALIVE and, since, it’s

alive, it must perform certain processes in order for it to meet the criteria for being alive. It’s got to

_____________, _____________________, ________________________, ________________ _____ ________________,

________________, and _____________________ (i.e. the processes of living things!). AND, in order to meet this

criteria and be able to do the aforementioned processes, it' gotta “capture”, “store”, and “use”

____________________ through the main life process of _______________________! HOW does it do all this…well,

this note-taking organizational chart will be your guide in finding out the answers to this problem…this

problem of HOW DO CELLS “CAPTURE”, “STORE” AND “USE” ENERGY?

                                            IT ALL STARTS WITH WHAT TYPE OF “EATER” YOU ARE AND WHAT KINGDOM YOU

WOULD BE CLASSIFIED IN…
