1) The mature parenchyma cell can dedifferentiate and proliferate.

2) Parenchyma cells have a middle lamella and a primary cell wall in their cell walls.

3) In the leaf mesophyll, parenchyma cells do not leave much intercellular space.

4) Shadow leaves show a palisade parenchyma with more parenchyma cell layers than those leaves under direct sunlight.

5) Storage parenchyma cells may contain particulated and disolved substances stored in their cytoplasm.

6) Photosynthetic parenchyma is found in the aerial parts of the plant body.

7) In aquatic plants, there are large intercellular spaces in the parenchyma filled with water.

8) In xerophyte plants, water is stored in large vacuoles.

9) The parenchyma tissue distributes in reduced areas of the body plant, such as the bark, and some cells in the xylem and phloem.

10) Parenchyma tissue can be used to generate new plant clones.
