Answer 1

The correct answer is Meristem.

Key Points

The meristem cells divide continuously and are found at the tips of plant roots, stem tips, etc.
Its cells can be round, oval, polygonal or rectangular.
These cells are tightly arranged, meaning they have no intercellular spaces between them.
Its cells have a thin cellulose cell wall.
Meristem cells have dense nuclei and cytoplasm.
Small or absent vacuoles.

Additional Information

Xylem:
- It is the main conducting tissue of vascular plants responsible for carrying water with inorganic solutes from the roots to all parts of the plant.
- Old Xylem forms wood and does not participate in transport.
- The age of the tree can be calculated by counting the xylem rings.
Parenchyma:
- There is an intercellular space between them.
- The cell wall is thin, surrounding the cytoplasm containing a small nucleus and a large vacuole.
Sclerenchyma:
- Consists of long, narrow, thick-walled dead cells.
- Thickened cell walls due to lignin deposition.
- Due to excessive thickening of the cell wall, its lumen or cell cavity is virtually absent.
