1. Paramecium & Chlamydomonas Characteristics of Life

2. PARAMECIUM (heterotroph)
CHLAMYDOMONAS (autotroph)

3. Characteristics of Life – MADE OF CELLS
PARAMECIUM
CHLAMYDOMONAS
UNICELLULAR
UNICELLULAR

4. HOMEOSTASIS
PARAMECIUM
CHLAMYDOMONAS
CONTRACTILE CAVUOLE MOVES OUT WATER BROUGH IN BY OSMOSIS (SIMILAR TO PLANTS)
GETS CARBON DIOXIDE (CO2) AND RELEASES OXYGEN (O2) VIA DIFFUSION

5. RESPONDS TO ENVIRONMENT
PARAMECIUM
CHLAMYDOMONAS
RESPONDS TO CHEMICAL IN FOOD
RESPONDS TO ELECTRICAL CURRENTS
USES CILIA TO MOVE
SENSITIVITY TO LIGHT – REGIONS NEAR FLAGELLA REACTS TO LIGHT CAUSING A “TURNING” MOTION FOR THE CELL.

6. GROWTH & DEVELOPMENT
PARAMECIUM
CHLAMYDOMONAS
FOOD BROUGHT IN TO CYTOPLASM IS ABSORBED AND USED IN METABOLIC PROCESSES.
PHOTOSYNTHESIS IS USED TO HELP GROW / MAKE OWN FOOD.

7. REPRODUCTION ASEXUAL – DIVIDES VIA FISSION
PARAMECIUM
CHLAMYDOMONAS
ASEXUAL – DIVIDES VIA FISSION
SEXUAL – HORIZONTAL GENE TRANSFER CAN OCCUR VIA CONJUGATION (SEX)
ASEXUAL – DIVIDES VIA FISSION; CELLS PRODUCED THIS WAY HAVE NO CELL WALL
SEXUAL – SOME CELLS THAT WERE CREATED ASEXUALLY WILL PAIR AND FUSE WITH EACH OTHER TO FORM A SINGLE UNIT AND CREATE A CELL WALL.

8. NUTRITION TAKES IN FOOD VIA ORAL GROOVE (CYTOSOME).
PARAMECIUM
CHLAMYDOMONAS
TAKES IN FOOD VIA ORAL GROOVE (CYTOSOME).
TAKES IN LIQUIDS VIA VACUOLE (LIKE PLANTS)
PHOTOSYNTHESIS – MAKES IT’S OWN FOOD.

9. METABOLISM
PARAMECIUM
CHLAMYDOMONAS
FOOD PARTICLES ARE ENCOLED WITH IN SMALL VACULOES THAT CONTAIN ENZYMES.
ENZYMES ARE USED FOR THE DIGESTION PROCESS.
PHOTOSYNTHESIS – CO2 IS CONVERTED TO COMPOUNDS NEEDED FOR GROWTH.
ENZYMES IN CYTOPLASM BREAK DOWN FOOD THAT IS CREATED FOR ENERGY.

10. EXCRETION SOLID WASTE – REMOVED VIA ANAL PORE
PARAMECIUM
CHLAMYDOMONAS
SOLID WASTE – REMOVED VIA ANAL PORE
LIQUID WASTE – REMOVED BY CONTRACTILE VACUOLE
DIFFUSION OF GASSES
CONTRACTILE VACUOLE FOR REMOVAL OF LIQUIDS
