Difference between Shoot apical meristem and Root apical meristem
Difference between Shoot apical meristem and Root apical meristem are in tabular form below –
No. |
Shoot apical meristem |
Root apical meristem |
Definition |
||
1. | A meristem which is the site of most of the embryogenesis in flowering plant and contains four distinct cell groups is referred as shoot apical meristem. | A small region which is present at the tip of root and the cells are dividing cells, this cells form all the root’s cells, and this is referred to as root apical meristem. |
Shape and length |
||
2. | This apical meristem is dome-shaped and is long when compared to root apical meristem. | This apical meristem is cup-shaped and is comparatively short. |
Protection |
||
3. | A crown of young leaves helps to protect this meristem. | A root cap helps to protect this meristem. |
Positive/Negative phototrophic and geotropic |
||
4. | This is positively phototrophic but negatively geotropic. | This is negatively phototrophic but positively geotropic. |
Formation |
||
5. | Shoot apical meristem forms organs like the flowers and leaves. | For future root growth, root apical meristem form cells. |
Primordia |
||
6. | In the shoot apical meristem, leaf primordia is present. | In the root apical meristem, leaf primordia is not present. |
