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: -Euglena move by using a flagellum, a long whip-like structure that functions as a small motor. The flagellum, which is located on the cell’s anterior (front) end, twirls to propel it through the water.

Detailed explanation-3: -Plant-like protists are commonly called algae. Some scientists prefer to classify Page 2 algae in the plant kingdom. Algae, like plants, can make their own food. Some live in the soil, some in the bark of trees, and some in water.

Detailed explanation-4: -Traditionally, Euglenas were classified under Domain Eukarya, Kingdom Protista, and Phylum Euglenozoa (sometimes Euglenophyta). However, it is widely recognized that Protista is not a natural grouping. Currently, Euglena is classified in the Kingdom Excavata.

Detailed explanation-5: -Euglenas create their own food through photosynthesis, the process of absorbing sunlight to synthesize foods from carbon dioxide and water. An eyespot at the front end of the euglena detects light, and its chloroplasts (structures that contain chlorophyll) trap the sunlight, allowing photosynthesis to occur.
