this ppt contain almost all the information about movements in different plants . lots of description about each n every topic with pics

1. Movements in plants

3. HYGROSCOPIC MOVEMENT:
• This is the movement of part of plant that is
caused by the influence of the change of the
water level from its cells so happens non-
homogeneous wrinkling.
• Example: the breaking of dried
Kalanchoe Pinnata fruit.
• The opening of sporangium in fern
as the cause of wrinkling annulus cells.

5. Endogenous movement
(autonomic)
• It is movements that is not known yet it causes
suddenly but predicted that this motion is
caused by stimulus that comes from the body
of plant itself.
• Example:
The flowing movement of cytoplasm in cell.
The blending movement of leaf bid because of
difference of growth velocity.

6. Exogenous movement:
etionom/esionom
It is plant movement that is
caused by external stimulus.
External stimulus such as:
Light, gravity, water, touch and
chemical substances .

7. The various kind of exogenous movement in plants:
Tropism movement
Nastic movement
Taxis movement

9. Phototropism :
• It is tropism movement that is
caused by stimulus of light.
• Examples
the tip of plant that
lie in the room will
bend to the direction
of incident of light.

10. Geotropism :
• It is tropism movement that follows earth
gravitational force.
• Positive geotropism: geotropism movement
that its direction is downwards.
• Negative geotropism: geotropism movement
that its direction is upwards.

12. Chemotropism
• Tropism movement that is caused by chemical
substances stimulus.
• Example:
the movement of roots toward the
fertilizer in the soil.

13. Thigmotropism:
• It is tropism movement that is caused by
stimulus of touch to the harder thing.
• Example:
 Tendril of plant movement.

14. Hydrotropism:
• It is the movement of the pant root that is
influenced by reservation of soil water.

15. Nastic movement:
• It is plant movement to stimulus, that its direction
is not determined by stimulus but by plant itself.
• Kinds if nastic movements:
1. Photonasty
2. Nictinasty
3. Thigmonasty
4. Thermonasty
5. Complex nasty.

16. Photonastic:
• Nasty movement caused by stimulus of light.
• Example:
• the opening of Mirabilis Jalapa flower
at certain time.

17. Nictinasty:
• Nasty movement that is caused by dark
condition.
• Example:
the closing of compound leaves of
Leucaena Leucocephala at night.

18. THIGHMONASTY / SEISMONASTY
• Nasty movement that is caused by stimulus of
touch.
• example:
the closing of Mimosa Pudica when touched

19. THERMONASTY:
• Nasty movement that is caused by temperature
stimulus.
• Example:
tulip flower will bloom if the temperature
rises.

20. COMPLEX NASTY:
• Nasty movement caused by several factors all
together.
• Example:
• the opening and closing of stomata is
influenced by light , chemical substances , and
water.

22. TAXIS MOVEMENT:
• Transfer movement of all parts of plants to
stimulus that its direction is determined by
stimulus.
• Kinds of taxis movements
• Photo taxis
• chemo taxis

23. Photo taxis:
• Taxis movement that is caused by stimulus of
light.
• Example :
• the movement of the chlorophyll to the
surface of the leaves to get the light.

24. CHEMO TAXIS:
• Taxis movement that is caused by chemical
substance stimulus.
• Example:
• movement of spermatozoid of moss
and fern to ovum that is found in
archeogonium attached to the sugar or protein
that is produced by archeogonium .
