Nastic movements are non-directional responsesto stimuli (e.g. temperature, humidity, light irradiance), and are usually associated with plants. The movement can be due to changes in turgor or changes in growth . Nastic movements differ from tropic movements in that the direction of tropic responses depends on the direction of the stimulus, whereas the direction of nastic movements is independent of the stimulus's position. The tropic movement is growth movement but nastic movement may or may not be growth movement. The rate or frequency of these responses increases as intensity of the stimulus increases. An example of such a response is the opening and closing of flowers (photonastic response), movement of euglena, chlamydomonas towards the source of light. They are named with the suffix "-nasty" and have prefixes that depend on the stimuli:
Epinasty: downward-bending from growth at the top, for example, the bending down of a heavy flower.[1]
Hyponasty
Photonasty: response to light
Nyctinasty: movements at night or in the dark
Chemonasty: response to chemicals or nutrients
Hydronasty: response to water
Thermonasty: response to temperature[2]
Geonasty/gravinasty: response to gravity
Thigmonasty/seismonasty/haptonasty: response to contact
The suffix may come from Greek νάσσω = "I press", ναστός = "pressed", ἐπιναστια = "the condition of being pressed upon".

Turgor movement is the reversal change in the position of a plant due to the turgor pressure on plant cells.
I think there is no type of turgor movement.
Hope that this helps you.
