| Autonomic Movements |
|
| Locomotion movement |
| It is the movement of the protoplasm. These are limited to aquatic plants and are free and spontaneous movements. |
| |
| Examples: Streaming of cytoplasm (cylosis), movement of cilia or flagella, motility of zoospores. |

| Protoplasmic movements |
| (a) ciliary (b) amoeboid (c) cyclosis (d) gliding |
| |
| Growth and curvature movements |
| Higher plants and most other plants remain attached to one place and do not move from place to place like animals. They can only change the direction of their organs by means of curvature. |
| |
| These movements take place due to the difference in the ratio of growth of different parts. It can be further classified as nutational or nastic movements. |
| |
| i) Nutation |
| |
| Movements as seen in twiners and climbers. This results in curvature and helps in twinning around the support. |

| |
| ii) Nastic Movements |
| |
| These movements are due to differences in the rate of growth on two opposite sides. |
| |
| Example: opening of the petals and circinately coiled leaves. |
| |
| iii) Movement of Variation |
| |
| Movement which takes place due to changes in the turgidity of cells. |
| |
| Example: Desmodium gyrans or the telegraph plant. The elliptical up and down movement of the 2 lateral leaflets is due to change in the turgidity of the cell. |
