Question

Name the starting points and destinations of each substances that stem transports.

Answer 1

The substances which are transported - mineral salts (ions) from the soil, and the products of photosynthesis from ... These vessels form a continuous "pipe" from the root to the stem and leaves

Answer 2

The phloem is towards the centre, outside the xylem. In the stem, the transport tissues of the xylem and phloem are grouped into vascular bundles . Any green part of a plant above ground, where it is exposed to light, can photosynthesise. But a plant's leaves are the main organ of photosynthesis.
