Botany - Biological Classification Question with Solution | TestHub
The given statements describe a group of organisms.
(i) Instead of a cell wall they have a protein rich pellicle making their body flexible.
(ii) They have 2 flagella, a short and a long one.
(iii) They show mixotrophic nutrition.
(iv) They are connecting links between plants and animals.
Which of the following groups is referred here?
Options:
Answer:
Solution:
Euglenoids are unicellular aquatic alga that belongs to the kingdom Protista. Many of these organisms exhibit characteristics of both plants and animals. In this many of them have 2 flagella that emerges out of the cytostome through cytopharynx and are motile. Out of the two flagella, one is short and the other one is a long one. Instead of cell walls, they have a protein-rich pellicle that helps in maintaining the definite shape of the body. Nutrition in Euglena is accomplished by holophytic (able to synthesize organic compounds by photosynthesis) or saprophytic (those organisms get its nourishment from dead organisms) or both so they show the mixotrophic mode of nutrition.
