GCSE Biology · key term
A region of plant tissue containing unspecialised cells that divide to produce new cells.
Used by AQA, Edexcel and OCR
Specification 4.1.2.3 · Paper 1
Plant tissue containing stem cells that can divide and differentiate into any type of plant cell throughout the plant's life.
Revise: Types and Functions of Stem CellsIn plants, stem cells occur in regions called meristems. Meristem tissue is found at growing regions such as the tips of roots and shoots. Its cells divide to make more cells; these cells can then enlarge and differentiate as the root or shoot grows.
Specification 2.5, 2.8 · Paper 1
In a comparison, use the correct range: embryonic stem cells can form most human cell types; adult bone-marrow stem cells can form many cell types, including blood cells; plant meristem cells can form any type of plant cell.
A plant meristem is a region of dividing, undifferentiated cells, not simply any cell found in a plant stem.
Keep the three sources distinct: embryonic stem cells can form essentially any body-cell type; adult stem cells usually form a limited range of related cells; meristems produce specialised plant cells.

A region of a plant containing cells that divide rapidly, found in growing areas such as root and shoot tips.
Cell division produces new cells by mitosis in regions called meristems, found at or just behind the tips of roots and shoots.
A region of unspecialised, actively dividing cells in a plant that produces cells for growth and differentiation.
Specification B2.1d, B2.1e · Paper 1 (Foundation), Paper 3 (Higher)
A region of plant tissue containing actively dividing, undifferentiated cells; examples occur at the growing tips of roots and shoots.
Revise: Presence of stem cellsPlants also contain stem cells. They are found in regions of tissue called meristems. Meristems occur at growing regions, including the tips of roots and shoots.
A region of plant tissue containing unspecialised cells that divide and differentiate to produce new growth.

Revise: Cell Cycle and MitosisAn onion root tip contains a meristem, a region that produces new cells as the root grows. A stained root-tip preparation is useful because staining makes the chromosomes easier to distinguish. A microscope slide captures many cells at one moment, so different cells may show different points in the cell cycle.
A region of a plant, such as a root or shoot tip, where cells divide to produce unspecialised cells that can become any type of plant cell.
