Euglena is a genus of microscopic, one-celled organisms in the Protista kingdom. There are about 150 species of euglenas. They live in fresh water, and are especially common in warm seasons when they may form a green scum on the surfaces of small ponds or drainage ditches. Euglenas have spindle-shaped bodies, and range in size from 1/1000 to 1/100 of an inch (0.025 to 0.254 millimeter) long.

Why is a sensory structure so important to the euglena?

A sensory structure, called a stigma, is crucial for the euglena to detect light intensity and direction, allowing it to move towards light for photosynthesis. This phototaxis behavior helps the euglena optimize its energy production.


What is the locomotory organ in euglena?

Are euglena free living or parasitic?

What function might the stigma of the Euglena serve?

The students are planning to write labels for their diagram, explaining how each part contributes to the function of the euglena. Which label would be most appropriate for the chloroplast? Responses "This structure helps the euglena obtain minerals from its environment so that it can perform life functions."

Is a euglena sexual or asexual?

Asexually. Many protozoans, such as Euglena or Amoeba, undergo binary fission, whereby a single-celled organism divides evenly into two identical cells. actually, if i remember right they are both.
