What is life????

 A living thing!!

 All living things are made of CELLS:  a) unicellular  b) multicellular  Organized:  tissues = group of cells ex: muscle  organ – group of tissues ex: skin  system = group of organs ex: circulatory system

 Organism obtains materials from its environment & prepares it for use  Ingestion:  Digestion  Egestion:

**

 Includes absorption of materials into the organism and distribution of the materials within the organism.

 Osmosis/diffusion

 Chemical processes by which an organism obtains energy from food materials in order to maintain its life functions.

 Removal of waste products produced within the organism as a result of metabolic activities.  Ex: sweating  urine  exhaling CO 2

!!

 Includes the chemical activities by which an organism builds large molecules from smaller ones.

 Is the control and coordination of the various activities of an organism, including response to stimuli

 The use of the products of synthesis to increase the cell size and/or the number of cells of an organism.

 Production of new individuals. Reproduction is necessary for the survival of the type of organism, or species.  Asexual = one parent (identical)  Sexual = two parents (not identical)  SORRY NO PICTURES !!!

 Asexual – tuber (underground stem swollen with food)

 Sexual – SORRY NO PICTURES!!!

 Maintenance a stable internal environment by means of the control & regulation of its metabolic activities.

 The sum total of all the chemical processes by which an organism carries on its life functions.

 VERY SLOWWW METABOLISM!

 Two baby Sloth Bears rescued from Traders

 Bear cubs are purchased for use as Dancing Bears and trained by using brutally and cruel techniques such as thrusting a red hot needle through their muzzle to insert a coarse rope through it to make them dance and entertain tourists.
