OBJECTIVESOBJECTIVESTo define Plant Ecology.
To determine the connection of plant reproduction,
biological interaction and distribution to plant ecology.
To differentiate the scene of the past, present and future
of plant diversity.
PLANT PLANT ECOLOGYECOLOGY
Plant Plant EcologyEcology
It is a sub-discipline of ecology which studies the distribution and abundance of plants, the
interactions among and between members of plant
species, and their interactions with their
environment.
includes the study of plants and their environment.
can include the study of entire ecosystems.
Plant Plant ReproductionReproductionPlant reproduction is the
production of new individuals or offspring in
plants, which can be accomplished by sexual
or asexual means.
Biological Biological InteractionsInteractions
In the natural world no organism exists in absolute
isolation.
It can involve individuals of the same species or
individuals of different species .
Biological Biological InteractionsInteractions
Competition
Facilitation
Herbivory
DistributionDistribution
Plant communities are broadly distributed into
biomes based on the structure of dominant
plant species.

PRESENTPRESENT
As we study the plant ecology, people can focus on
topics like climate change and its effect on plants,
plant evolution, how plants disseminate themselves in
nature, symbiotic relationships between plant species, plant diseases, and
so forth.
