Euglena, Amoeba and paramecium are unicellular organisms. Euglena moves by flagellates, Amoeba by pseudopods and paramecium moves using cilia.

Unicellular organisms are lower level organisms having only one cell and an undeveloped nucleus. Most of them are aquatic lives and moves using some special organelles.

Amoeba moves by an arm-like structure emerging from its body and contains microtubules within the arms. Euglena is flagellated microorganism moving by flagella.

Paramecium is an aquatic unicellular microorganism having special whip like structure called cilia which moves it in back forth. Ciliary bodies are like oars to move in a direction.

Therefore, amoeba moves by pseudopodium, euglena moves by flagella's and paramecium moves by cilia.

Then give the ruler (or similar object) a harder downward pull, and see if there is a difference in sound. Describe what you hear and explain the difference using the terms “energy,” “amplitude,” “intensity,” and “decibel.”


2. Take some time to listen to sounds in your environment. Make a list of ten sounds, ranking them from the highest pitch to the lowest. Write a couple of sentences describing whether this was easy or difficult and why. (Some of the sounds can come from tapping objects that vibrate or playing musical notes on an instrument.)
