Plants transport organic compounds (like sugars) from sources (leaves) to sinks (flowers, roots). Transport occurs along hydrostatic pressure gradients. Active transport causes high concentrations of solutes in the phloem sieve tubes at the source. This leads to water uptake by osmosis and raised hydrostatic pressure.

A class of related plant hormones that stimulate growth in the stem and leaves, trigger the germination of seeds and breaking of bud dormancy, and stimulate fruit development with auxin. An animal that carries pollen from one plant to another of the same species, enabling plants to reproduce. roots, stems and leaves that a young plant forms when the seed germinated; trigger causes plant to change into the reproductive phase light plays a role in the production of either inhibitors or activators of genes that control flowering 9.4: Reproduction in Plants I give many of my IB Biology resources away, for the benefit of students and teachers around the world.
