Question

role of ecophysiology in plant distribution

Answer 1

A species can be evolved on a particular location, introduced (either naturally or by human aids) or it can get extint. All these distributions are closely associated with echophysiology which studies how plants respond to the environmental conditions.

Plant get distributed into biome like grass land (where dominent species is grass) forest (dominent species : trees) this distributions are clearly based on the peculiarity of the location (like elivation, geographical position, temperature etc). A grass species from a tropical grassland may not survive in an evergreen forest, because of low sunlight. But their are plant species that are adapted to grow under thick canopies. These type of ecological factore leads to accumulation of favourable adaptations and cause speciation and unfavourable cause extinction.

Plants are phentypically plastic (cannot move) so they have a huge set of genes for adapting unfavourable conditions. Some plants has even let animals carry their seeds so that they get dispersed. Seeds are some time carried by water, wind etc.

With this we can conclude that plant distribution is verymuch associated with ecophysiology
