Q. No.
Mode of nutrition in euglenoids is:
1. Photosynthetic
2. Heterotrophic
3. Chemosynthetic
4. Both 1. & 2.
Euglenoids do not possess this feature-
(1) Always photosynthetic
(2) Pigments like higher plants
(3) Pellicle provides flexibility
(4) Found in stagnant water
Which of the following have pigment similar to higher
plants?
1. Group which causes red tide.
2. Group which is chief producer of ocean.
3. Group when deprived of light behaves as heterotroph.
4. Group where spore have cellulosic cell wall
Which of the following statements regarding Euglenoids is not true?
| 1. | Instead of a cell wall, they have a lipid rich pellicle |
| 2. | They have two flagella, a short and a long one |
| 3. | They are photosynthetic in the presence of sunlight but behave like a heterotroph when deprived of sunlight |
| 4. | Pigments of Euglenoids are identical to those present in higher plants |
…….of dinoflagellates have …..flagella …..lie in a furrow between wall plates
(1) All, 2, both
(2) Many, 3, trasverse falgella
(3) Most, 2, both
(4) All, 3, longitudinal flagella
Euglenoids can be/have
(1) Predator
(2) With cell wall
