NEET BIOLOGY

Detailed explanation-1: -Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyta. All euglena have chloroplasts and can make their own food by photosynthesis. They are not completely autotrophic though, euglena can also absorb food from their environment.

Detailed explanation-2: -Euglenids have many unique cellular structures, some of which include their flagella, eyespot, contractile vacuole, and chloroplasts. The eyespot helps the organism to detect light sources in order to photosynthesize.

Detailed explanation-3: -Euglena have two flagella rooted in basal bodies located in a small reservoir at the front of the cell. Typically, one flagellum is very short, and does not protrude from the cell, while the other is long enough to be seen with light microscopy.

Detailed explanation-4: -Euglena is autotrophic and heterotrophic both.

Detailed explanation-5: -As photosynthetic protists, Euglena have a taxonomy that is somewhat contentious, and the genus is usually placed in the phylum Euglenozoa. Previous classifications placed the genus in the algal phylum Euglenophyta.
