Euglena, one of the most common flagellated protozoa, has a red despot which is important for a. detecting colors. b. being able to see food sources. c. detecting light for photosynthesis.

C. Detecting light for photosynthesis.

Explanation:

An Euglena is a protozoan. It has an single cell which makes it a unicellular organism. It is also has a well defined nucleus with membrane bound organelles which makes the Euglena eukaryotic in nature.

An Euglena possesses both human and plant like traits. Its human trait is that an Euglena moves with the aid of a flagella. Its plant like trait is that an Euglena has chloroplast present as one of its membrane bound organelles which its uses for photosynthesis.

Due to the presence of animal and plant like traits in an Euglena, and Euglena is both autotrophic and heterotrophic in nature.

One of the organelles present in the Euglena is its eyespot. This is a very important organelle because the Euglena uses the eyespot to detect sunlight for the process of photosynthesis. The chloroplast then traps this detected light for photosynthesis.

c. would be the answer : )

explanation:

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
