1.3 functions of unicellular organisms Flashcards
paramecium cell structure
eukaryotic
paramecium metabolism
cytoplasm contains dissolved enzymes that catalyze metabolic reactions
-ie digestion and synthesis of cellular structures
paramecium reproduction
nucleus divides via mitosis to make another nucleus before asexual reproduction.
two paramecium can fuse before division for sexual reproduction
paramecium sensitivity and response
controls beating cilia to move in different directions in response to environmental changes
paramecium energy and matter
heterotroph, uses the oral groove
paramecium homeostasis
expels excess water within the cell via the contractile vacuole
paramecium excretion
waste products from digestion are excreted via the anal pore
paramecium growth + development
the cell continues to grow until it reaches a maximum surface area-to-volume ratio, when it will divide.
adapt and evolve
all structures and behavior of the organism are the result of evolutionary processes, resulting in organisms that are adapted to the environment that they live in
chlamydomonas cell structure
eukaryotic
chlamydomonas metabolism
cytoplasm and chloroplast contain dissolved enzymes that catalyze metabolic reactions
chlamydomonas reproduction
nucleus divides via mitosis to make another nucleus before asexual reproduction.
two chlamydmonas can fuse before division for sexual reproduction
chlamydomonas sensitivity and response
light-sensitive eye-spot allows it to sense and move towards light. the flagella swim towards the light.
chlamydomonas energy and matter
autotroph (photosynthesis), uses chloroplasts
chlamydomonas homeostasis
contractile vacuoles expel excess water within the cell
