Answer 1

Answer:

Plants. Plants have evolved by using special structures within their cells to harness energy directly from sunlight. ... Parenchyma cells in plants provide mechanical support when they become lignified and thick‑walled.

Or

Parenchyma forms the bulk of plant ground tissue, where they may be specialised to function in photosynthesis, storage, or transport. Parenchyma is integral to vascular tissue, where it provides a route of exchange for materials within and between the xylem and the phloem.
