Reproduction in Plants
Off-springs of plants are produced through two means
• Sexual reproduction and
• Asexual reproduction

Plant’s self-defence
Plants may appear to be helpless in the face of
hungry, but many plants have evolved interesting
systems of self-defense.
Some of them are:
• Toxins
• Stings
• Blade of coarse grass
• Emission of gases etc
If you think that….
Plants are at the bottom of the food chain for a
reason. Having no brains or feelings or ability
to move or sense of humour, they fit the
definition of "organism" only on a most basic
level.
Which is very very …. wrong
Factors demanding the existence of brain in
plants
• They have structures analogous to neurons in
animals
• They can communicate, respond, fight etc.
• They can even do complex algorithms.
• Ability to memorize things (mimosa).
Mimosa
• Ability to communicate with and alarm other
plants
by chemical signaling.
• They have ability to respond to around 15 to 20
Environmental variables.
• Can they read your mind? (backster experiment).
Plant’s reaction at the imaged intension to burn
• They can produce electrical impulses similar to
impulses produced by neurons in animals(venus fly
