2. Cell wall: function and biosynthesis of primary and secondary cell wall. Surface protection.
3. Water balance in plants: uptake, movement from the root to the atmosphere. Water potential of plant cell, plant water status, root pressure, transpiration, guttation.
4. Solute transport across membranes. Mineral nutrition: uptake and translocation of mineral nutrients, nutritional needs of plants.
5. Assimilation of nitrogen, sulfur, phosphate, oxygen and cations. Biological nitrogen fixation. Mycorrhizae.

7. Carbon reactions of photosynthesis (the Calvin cycle), synthesis of starch and sucrose. Photorespiration. C3-, C4- and CAM plants. Control and regulation of photosynthesis.
8. Physiological and ecological considerations of photosynthesis. Translocation in the phloem. Parasitic and carnivorous plants.
9. Respiration process and its specificities in plant cell: glycolysis, pentose phosphate pathway, citric acid cycle, mitochondrial electron transport and ATP synthesis, control and regulation of respiration. Respiration of intact plants and tissues. Starch and lipid metabolism in germinating seeds.
10. Secondary metabolites in plants: role and distribution in plant species, structure, biosynthetic pathways.
11. Plant growth regulators: auxins, gibberellins (structure, biosynthesis, translocation, physiological effects).
