<p>Amoeba proteus moves using pseudopodia, which are 'false feet' that create a leg on the fly. This movement method allows Amoeba proteus to capture and engulf its prey, such as algae, bacteria, unicellular eukaryotes, rotifers, and other microscopic organisms through phagocytosis.</p> Signup and view all the answers

<p>The contractile vacuole in Amoeba proteus serves as an organelle for osmoregulation, expelling excess water from the cell by releasing a clear bubble. This process is vital for maintaining the cell's internal balance and preventing it from bursting due to osmotic pressure.</p> Signup and view all the answers

<p>Phylum Euglenozoa is known for its unique feature of having a flagellum, which is essential for movement and navigation in its environment. This characteristic distinguishes Euglenozoa from other unicellular eukaryotes and contributes to its ecological adaptation.</p> Signup and view all the answers
