Control of plant growth Flashcards
What is the communication pathway in plants?
Environment -> Sensory input -> Cell signalling -> Output
Where is plant division limited to?
Meristems
What is the main meristem?
The shoot apical meristem for primary growth
What is the main meristem found?
The top of the stem
What is the main growing root?
The root apical meristem for primary growth
Where is the main growing root found?
The tip of the roots
What is found in the meristem?
A zone of elongation and then division
What is the lateral meristem?
Allows with of shoots and roots to increase (cambium) for secondary growth
Where is the lateral meristem?
Outside of shoots and roots
What is primary growth?
Getting longer
What is secondary growth?
Getting wider
What is the intercalary meristem?
Increases the distance between leaves
Where is the intercalary meristem?
Between nodes
What are the main meristem?
Shoot apical, root apical, lateral and intercalary
What controls plant growth?
Tropism, apical dominance and stem elongation
