Plants have a hierachical organisation consisting of:
- Organs
- Tissue
- Cells
- Organs
-
The basic vascular plant organs:
- Roots (roots system)
- Stems (shoot system)
- Leaves (shoot system)
- Roots (roots system)
-
Above ground (shoot system), the plant takes up:
CO2 and light -
On what do the roots and shoots rely on?
-Roots rely on sugar produced by photosynthesis in the shootsystem
-shoots rely on water and minerals absorbed by the rootsystem -
What is the connection between shoot and root system?
Vascular tissue -
Where is the apical bud located?
At the top of the plant, primary growing point -
Where is the axillary bud located?
In the upper angle/axil of a leaf -
Taproot system (dicot):
A taproot system consists of one main vertical root, that gives rise to lateral roots, or branch roots -
Fibrous root system (monocot):
Seedless vascular plants and monocots have a fibrous root system, characterized by thin laternal roots with no main roots. -
What does the apical bud do?
It causes elongation of a young shoot
