Euglena reproduce asexually through binary fission, a form of cell division. Reproduction begins with the mitosis of the cell nucleus, followed by the division of the cell itself. Euglena divide longitudinally, beginning at the front end of the cell, with the duplication of flagellar processes, gullet and stigma.
Modern evolutionary studies have discovered that these organisms represent the earliest diverging lineages of eukaryotes. We collectively call this artificial assemblage protists. The protists are diverse. This chapter focuses on the photosynthetic protists, informally called algae.
- Euglena are unicellular protists that can be classified in the Kingdom Protista and Phylum Euglenophyta. - They contain chloroplasts that allow them to photosynthesize but can also absorb nutrients, making them both autotrophic and heterotrophic.
Ex: Euglena, Ceratium, Noctiluca Class 2: Zoomastigophora (Gr. Zoon=animal; Mastix=whip; phoros=bearing) These organisms do not have chlorophyll bearing chromatophores. These are mostly parasitic. The nutrition in these organisms is holozoic or saprozoic. The reserved food is glycogen. They may have one to many flagella.
Euglena are protists that have both animal-like and plant-like characteristics. Based on your observations, list at least one characteristic that euglenas have in common with animals and one characteristic they have in common with plants.
27 mar 2024 · What are Protists? What is the Structure of the Euglena? The Euglena has a spindle-shaped body with a pellicle for support, a single nucleus, chloroplasts for photosynthesis, and a red eyespot for light detection. What is Euglena Shaped like?
