Paramecium Functions of Life |
Nutrition - ingest small organisms and digest them through endocytosis Growth - nutrients from digestion are used to provide energy and materials required for growth Excretion - waste products from metabolism are expelled from the cell by diffusing out the membrane Response - the cilia help the cell move around, the paramecium moves toward or away from external stimuli Metabolism - contains enzymes in the cytoplasm which catalyze the metabolic reactions Reproduction - asexual (mitosis) as well as sexual reproduction (meiosis and gametes) Homeostasis - contractile vacuoles in the cell fill up with water and remove this water from the cell by expelling it through the cell membrane, this maintains the water levels in the cell relatively constant |

Chlamydomonas Functions of Life |
Nutrition- contains a chloroplast and thereby produces its own food via photosynthesis Growth - is able to grow through the absorption of minerals and photosynthesis Excretion - waste products such as oxygen deriving from photosynthesis are expelled outside the cell through diffusion Response - has an eyespot that is able to detect the brightest light, the chlamydomonas moves towards the light stimuli Metabolism - contains enzymes in the cytoplasm which catalyze the metabolic reactions Reproduction - asexual (mitosis) as well as sexual reproduction Homeostasis - contractile vacuoles in the cell fill up with water and remove this water from the cell by expelling it through the cell membrane, this maintains the water levels in the cell relatively constant |
