A
When something gets longer (such as a cell in a plant root or shoot before it differentiates into a specialised cell).
3
Q
Meristem
A
A small area of undifferentiated cells in a plant, such as near the shoot tips and root tips, where cells are dividing rapidly by mitosis.
4
Q
Root hair cell
A
Cell found on the surface of plant roots that has a large surface area to absorb water and dissolved mineral salts quickly from the soil.
5
Q
Xylem cell
A
Cell that joins with other xylem cells to form long, thick-walled vessels after they die. The vessels carry water and dissolved mineral salts through the plant.
