Can plants also use locomotion

Are there moving plants?

It depends on how you do that Locomotion define.

If you assume you will move from one place to another then almost all plants do this at some point during their life cycle. Primarily, seeds and pollen move, and generally they either use natural forces like wind and rain, or manipulate animals to do the leg work, e.g.

  • by recruiting pollinating insects
  • by barbs that get caught on the fur of passing mammals
  • By producing tasty fruit, monkeys will eat them, including seeds, and put them elsewhere with a dash of manure

If you understand it like you do move under their own drive then some plants do so. The example that comes to mind is the gametophyte generation of ferns:

The prothallus (i.e. the gametophyte) has rhizoids on the underside and uses them to slide around and find some space to start the next generation. I've seen this happen when fern spores germinate on agar - when they reach the tiny prothallus stage they slide around to avoid overlapping. I can't find any references for this, but I'll keep looking.

Another example of self-directed locomotion in plants is the motile sperm of bryophytes. The male sex cells have flagella with which they move through water to the female sex cells (review by Renzaglia & Garbary 2001).
