The amoeba, euglena, and paramecium all have different means of locomotion. How are they different,? Are there any similarities?

The amoeba uses pseudopods, which it creates by deforming its body and streaming its cytoplasm. The euglena whips a flagellum to move. The only similarity between the amoeba and euglena in that the euglena can deform its body in an almost earthworm-type motion. This is something like the amoeba's motion and is used to supplement the euglena's flagellum when it wants to move quickly.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
