Paramecium & Chlamydomonas Characteristics of Life

PARAMECIUM (heterotroph) CHLAMYDOMONAS (autotroph)

Characteristics of Life – MADE OF CELLS PARAMECIUM CHLAMYDOMONAS • UNICELLULAR

HOMEOSTASIS PARAMECIUM CHLAMYDOMONAS • CONTRACTILE CAVUOLE MOVES OUT WATER BROUGH IN BY OSMOSIS (SIMILAR TO PLANTS) • GETS CARBON DIOXIDE (CO 2) AND RELEASES OXYGEN (O 2) VIA DIFFUSION

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

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

REPRODUCTION PARAMECIUM • ASEXUAL – DIVIDES VIA FISSION • SEXUAL – HORIZONTAL GENE TRANSFER CAN OCCUR VIA CONJUGATION (SEX) CHLAMYDOMONAS • 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.

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

METABOLISM PARAMECIUM • FOOD PARTICLES ARE ENCOLED WITH IN SMALL VACULOES THAT CONTAIN ENZYMES. • ENZYMES ARE USED FOR THE DIGESTION PROCESS. CHLAMYDOMONAS • PHOTOSYNTHESIS – CO 2 IS CONVERTED TO COMPOUNDS NEEDED FOR GROWTH. • ENZYMES IN CYTOPLASM BREAK DOWN FOOD THAT IS CREATED FOR ENERGY.

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