Shoot architechture and light capture Flashcards
How the length of the stem and the branching patterns are deigned ?
for what purpose?
To capture maximum light.
Why plants grow tall?
To avoid shading from neighbouring plants.
Adaptation of stems to obtain maximum light?
growing taller, vines
- Most tall plants have thick stem with strong mechanical support.
- woody plants undergo secondary growth thereby make there tall stem stronger
- vines rely on other objects to reach higher levels to capture more light.
what is gained by thick stem ?
strong mechanical support to tall plants.
what growth make tall stem stronger?
what plants undergo thta growth ?
Secondary growth
woody perennial including all gymnosperms and many dicots.
vines rely on what?
on other objects
vines rely on other objects for what?
to reach higher levels
why vines reach higher levels?
to capture more light.
What happen secondary growth of woody plants?
Make tall stem stronger
Do all plants have the same branching pattern?
NO
There is a variety of branching pattern.
Are there unbranched plants?
YEs both unbranched and well branched plants occur.
what is the importance of having variation i branching pattern?
enable plants to absorb maximum light in the ecological niche it occupies
Size of the leaves vary based on what?
Base on the place where the plant grows.
Where the plants with largest leaves are present?
In rain forests.
Plants inhabiting which environments have small leaves?
DRY OR VERY COLD ENVIRONMENTS
