When toxins enter a plant, they most likely travel through the apoplastic pathway, which involves movement through the spaces between cells and cell walls. This pathway allows for relatively unrestricted flow, enabling toxins to quickly spread throughout the plant tissues. Alternatively, toxins can also enter through the symplastic pathway, moving from cell to cell via plasmodesmata, but the apoplastic route is generally the first line of transport. Ultimately, the specific pathway may depend on the type of toxin and the plant's response mechanisms.
The pathway that the toxins would most likely follow on first entering the plant is PHLOEM.

These structures are called stomata, which are small pores present on the surface of plant leaves. Stomata open to allow carbon dioxide to enter the plant for photosynthesis and close to prevent excessive water loss. Oxygen produced during photosynthesis exits the plant through these stomata as well.
