Q. No.Mycoplasma are similar to Euglenoids in that both:
1. are obligate aerobes
2. are heterotrophs
3. lack a cell wall
4. cause harmful blooms in water bodies
The cell surface of Euglena is unique amongst eukaryotes. It is called
1. Pellicle
2. Tunica
3. Cuticle
4. Exodermis

Majority of Euglenoids are freshwater organisms found in stagnant water. Instead of cell wall, they
have a protein rich layer called _____(a)________which makes their body flexible. They have
_____(b)______flagella; (a) & (b) are respectively.
1. (a) Pellicle (b) One
2. (a) Pellicle, (b) Three
3. (a) Gelatinous sheath, (b) Two
4. (a)Pellicle (b) Two
What is absent in Euglenoids?
| 1. | Two flagella, a short and a long one. |
| 2. | Pellicle, a protein-rich layer. |
| 3. | Pigments identical to those present in higher plants. |
| 4. | Cell wall with stiff cellulose plates. |
