Distribute the products of photosynthesis around the plant
phloem
The plant would wilt and die as it would not be able to receive water from the roots. For this reason cut flowers are placed in water to extend their life. If a vascular plant is subjected to cut its phloem in the stem region (leaving its xylem tissue intact), this plant will die of starvation because transportation of water and menerals is done by xylem and phloem transports the prepared food material to different plant parts. In a situation where phloem is dis-connected to the roots, the food supply to the roots will be stopped. Thus roots in the absence of nourishment will not be able to absorb water and minerals and the plant will die ultimately.
phloem
Without xylem cells, a plant would be unable to transport water and nutrients from the roots to the rest of the plant. This would result in wilting, stunted growth, and ultimately lead to the plant's death. Xylem cells are crucial for water uptake and support within the plant.
The cells would be unable to photosynthesise, and no glucose would be made. Therefore the plant would not be able to sustain itself and would simply die.
If all the xylem and phloem were not destroyed parts of the plant may survive but others would die, but eventually the whole plant would die because of lack of nutrients. If the xylem and phloem were all destroyed when the plant would die as it would receive no water or nutrients it needs.

It is the phloem. The stem connects all the plant parts. And in the stem are two kinds of tubes: the xylem and the phloem. The xylem transports water and mineral salts from the roots to the rest of the plant. The phloem transports food from the leaves to the rest of the plant. Sugar is considered to be food for plants and therefore the answer is the phloem. If you need not specific details, the stem would be an okay answer.

Depends on your plant and its size. In dicots, the xylem in the interior of the stem becomes "heartwood" as the plant gets bigger, and in this state helps hold up the tree. Reversing xylem and phloem in this situation would give you a plant without heartwood and therefore not able to grow to a large size. In monocots, no problem. Monocots have "vascular bundles" which have both xylem and phloem; these occur throughout the stem.

phloem
Sugars, amino acids, and hormones are substances typically found in phloem sap but not in xylem sap. These substances are transported in the phloem to various parts of the plant for growth and energy production.
The glucose (simplest form of sugar) made by the leaves through photosynthesis (process at which plants make food) got "stuck" as the phloem (food-carrying tube) is cut away and glucose could not be transported to below the part which the phloem was cut. Water from the roots would still flow to all plant parts as the xylem (water-carrying tubes) were not cut away. Hope this is useful! =)
The pathway that the toxins would most likely follow on first entering the plant is PHLOEM.
Then the pollen would not be able to reach the ovule therefore it will not be able to make a seed
