Eukaryotic alga are the organism in which photosynthesis occurs in the chloroplast and cellular respiration takes place in the mitochondria. Thus, to monitor both photosynthesis and cellular respiration, EUKARYOTIC ALGA should be used.
Eukaryotic algal cells are good idea to study photosynthesis and cellular respiration because these cells have both cell organelles chloroplast and mitochondria. Algal cells grow faster and require less space for their growth. These require sunlight for photosynthesis and temperature plays an important role in the growth of these cells.
