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
Reproduction - asexual (mitosis) as well as sexual reproduction
Unicellular Organisms Carry-Out All Functions of Life
nutrition, growth, response, excretion, metabolism, homeostasis and reproduction
