Paramecium and Chlamydomonas Flashcards
Paramecium; Homeostasis
Contractile vacuoles remove water from the cell to keep the water content in the cell within a reasonable limit.
Paramecium; Made of one or more cells
Paramecium is a unicellular organism with nuclei and many other organelles
Chlamydomonas; Made of one or more cells
Chlamydomonas are unicellular organisms with nuclei and many other organelles
Paramecium; response to environment
Control beating of cilia to move in different directions in response to changes in the environment
Paramecium; Grow and/or Develop
Cell will enlarge until a maximum size, at which it will divide
Paramecium; Reproduce
Nucleus of cell divides via mitosis to make extra nuclei needed for cell to reproduce (usually asexual)
Paramecium; Nutrition
Paramecium consumes smaller organisms (because it is a heterotroph) that are packaged into food vacuoles.
“Food” is gradually digested and absorbed into cytoplasm
Paramecium; Excretion
Waste products are excreted through anal pore
Chlamydomonas; Homeostasis
Contractile vacuoles remove water from the cell to keep the water content in the cell within a reasonable limit.
Chlamydomonas; response to environment
light sensitive “eyespot” can sense bright light and swim to it using its flagella
Chlamydomonas; reproduce
Nucleus of cell divides via mitosis to make extra nuclei needed for cell to reproduce (usually asexual)
Chlamydomonas; grow and/or develop
Photosynthesis happens inside the cytoplasm
(CO2 is converted to compounds needed for growth)
(Autotroph)
Chlamydomonas; metabolism
Cytoplasm contains enzymes that break down substances to release energy
Paramecium; metabolism
Cytoplasm contains enzymes that break down substances to release energy
Chlamydomonas; excrete
Excretes O2 through cell membrane
