Leaf disks photosynthesis lab
WebThis SAPS teaching resource provides a fun way for students to get hands-on when investigating photosynthesis, using an easily quantifiable and reliable procedure. Students punch out small discs from leaves, and float them in a syringe of sodium hydrogen carbonate solution. Once gas is evolved by photosynthesis, the leaf discs rise and fall. WebWhen the leaves go through the process of a light-dependent reaction by being placed in water, oxygen is created through photosynthesis and is released into the interior of the leaf. This causes the leaf to rise. However, since cellular respiration is happening at the same time, the oxygen is also being used up. This means that the leaves must
