Question

water sample from a local pond. one sample contains euglenas. euglenas are unicellular organisms that live in fresh water. a euglena has a flagellum to help it move through the water. it also has a red spot that detects light as its chloroplasts need the suns energy for photosynthesis. object visible to the naked eye cells are visible under a microscope absorbs water moves in the wind grass yes yes yes yes onion plant yes yes yes yes rock yes no yes no soil yes no yes yes 3 the other sample contains a freshwater plant known as anacharis. the anacharis plant has bright green leaves, arranged around a stem, that carry out photosynthesis. the organisms in both samples produce food and oxygen for organisms in the water. the table compares the appearance of each organism with the naked eye, using a hand lens, and under a microscope. which best describes why the euglena is considered a unicellular organism?

Explanation:

Unicellular organisms are made up of one cell that performs all life - sustaining functions. Euglena is single - celled and its single cell has structures like flagellum for movement, eye spot for light detection and chloroplasts for photosynthesis, enabling it to perform all necessary functions for survival.

Answer:

It performs all of the functions for survival
