Transport of Molecules in Plant Questions

Plant gas exchange — By what physical process do CO2 and O2 normally enter and leave plant tissues through stomata?

Phloem transport — What is the widely accepted mechanism explaining long-distance movement of sugars in the phloem of vascular plants?

Mineral nutrition — The uptake of most mineral ions, including potassium (K+), into root cells occurs primarily by which mechanism?

Water relations — By which process does water primarily move from soil into the root cells of plants across the plasma membrane?

Stomatal physiology — What happens to stomatal aperture when guard cells swell (become turgid)?

Xylem transport — The cohesion–tension theory primarily explains water movement through which conducting tissue in vascular plants?

Leaf water loss — The process describing evaporation of water from plant leaves (primarily through stomata) is called what?

Phloem anatomy — Which cell types make up the functional conducting tissue of phloem in angiosperms?
