The cells of the xylem and phloem have distinct differences in their structure and function. Here’s a comparison:
- Cell Wall Thickness: Xylem cells have thick cell walls, which provide structural support to the plant. In contrast, phloem cells have thinner cell walls.
- Cell Size: Xylem cells are generally larger in size compared to phloem cells. This is because xylem cells are responsible for transporting water and minerals from the roots to the rest of the plant, requiring a larger volume.
- Presence of Chloroplasts: Xylem cells do not contain chloroplasts, as their primary function is not photosynthesis. Phloem cells, on the other hand, may contain chloroplasts, especially in the companion cells, which assist in the transport of sugars produced during photosynthesis.
These differences highlight the specialized roles that xylem and phloem cells play in the overall function and health of the plant.
