Ch-08: Plant Physiology

 Ch-08: Plant Physiology

This chapter covers mineral nutrition, categorizing nutrients into macro and micro-nutrients, and highlighting the roles of nitrogen and magnesium. It explains transport needs and the structure of roots and root hairs for water and mineral absorption (active and passive). Transpiration is described, linking it to stomatal function and environmental factors. Food translocation via the pressure-flow mechanism is explained, alongside gaseous exchange, homeostasis, and adaptations for excretion and osmotic adjustment.
