monocot
Monocotyledons , commonly referred to as monocots, are flowering plants whose seeds typically contain only one embryonic leaf, or cotyledon
gravitropism
Gravitropism is a turning or growth movement by a plant or fungus in response to gravity
phototropism
Phototropism is the growth of an organism which responds to a light stimulus
plant physiology
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants
thigmotropism
Thigmotropism is a directional growth movement of curvature which occurs in response to stimulus of contact
Chemoreceptors
A chemoreceptor, also known as chemosensor, is a sensory receptor that transduces a chemical signal into an action potential
stimulus
In physiology, a stimulus is a detectable change in the internal or external environment
Nastic
Nastic movements are non-directional responses to stimuli , and are usually associated with plants
life cycle
In biology, a life cycle is a series of changes in form that an organism undergoes, returning to the starting state
seed
A seed is an embryonic plant enclosed in a protective outer covering
dicot
The dicotyledons, also known as dicots , were one of the two groups into which all the flowering plants or angiosperms were formerly divided
auxin
Auxins are a class of plant hormones with some morphogen-like characteristics
circadian rhythms
A circadian rhythm /sÉœË?rˈkeɪdiÉ™n/ is any biological process that displays an endogenous, entrainable oscillation of about 24 hours
