Plant Movements: Tropism and Nastic Responses
Covers various types of plant movements including tropisms (phototropism, geotropism, thigmotropism, hydrotropism) and nastic movements (epinasty, nyctinasty, haptonasty), as well as cellular movements like cyclosis and amoeboid movement in plant cells.
