General principles of regulation of plant growth and morphogenesis
Review questions and tasks

1. Name the systems regulating plant morphogenesis at the cellular and whole-Organism levels.

2. Characterize the metabolic, membrane, and genetic regulatory systems.

3. What is morphogenetic RNA?

4. Explain how coordinated Gene activation is achieved. What is The basis of positional information?

5. What are the features of Trophic regulation?

6. What is The Significance of the hormonal regulatory system for multicellular plant organisms?

7. What are phytohormones? Which phytohormones do you know? Is there a clear boundary between growth-stimulating and growth-inhibiting Hormones?

8. What was THE CONTRIBUTION OF N.G. Kholodny to The Development of phytohormonology?

9. What is the Chemical Nature of phytohormones? Which types of hormones share similar steps in their Biosynthesis? What is the physiological significance of this?

10. Name the main manifestations of the physiological action of Auxins, Gibberellins, Cytokinins, as well as Abscisic acid and Ethylene.

11. How does The transport of auxins take place?

12. Why did Evolutionary Processes establish the pattern whereby morphogenic processes are regulated not by a single hormone, but by their ratio?

13. Explain the Basic principles of Electrophysiological regulation.

14. How is the Integration of regulatory mechanisms accomplished at the level of the whole plant?
