Aims • Definition of protoplasmic streaming • Formulate if the protoplasmic streaming is random• Effect of NaCl solutions on protoplasmic streaming • Speed of plasmolysis by osmosis • Prove of toxicity in the plant cells (CuSO4 ∙ 5H2O)
• Speed of chloroplasts on the cytoplasmic filaments • Space reconstruction of the elodea cell

Methods
• Preparing different sections • Microcinematography techniques • Microscope techniques (optical microscope, fluorescent
microscope) • Analysis in softwares (NIS elements, ImageJ, IC capture,
Obtahovač) • Statistical analysis (MS Excel)

Conclusions
• Streaming in protoplasma is random movement• Movement is slower on cytoplasmatic filaments • Hypotonic and hypertonic solutions influence sizes of
the chloroplasts• Experimental verification of the theoretical model• mastery of methods and microcinematography
