Statement I: | Dinoflagellates are mostly marine and photosynthetic. |
Statement II: | Majority of Euglenoids are fresh water organisms. |
1. | Statement I is correct; Statement II is correct |
2. | Statement I is correct; Statement II is incorrect |
3. | Statement I is incorrect; Statement II is correct |
4. | Statement I is incorrect; Statement II is incorrect |
I. | most dinoflagellates |
II. | euglenoids |
The body of Euglenoids is flexible because of presence of:
1. | a cell wall made up of pseudopeptidoglycan |
2. | a protein rich pellicle and absence of cell wall |
3. | a phosphate ether bonding in phospholipids in cell membrane |
4. | lipopolysaccharide layer in the outer cell wall |
Identify the incorrect statement regarding Euglenoids:
1. | Majority are found in fresh stagnant water |
2. | Presence of two flagella |
3. | Behave as heterotrophs when deprived of sunlight |
4. | Pigments entirely different from those found in higher plants |
I: | The majority of them are freshwater organisms found in stagnant water. |
II: | Instead of a cell wall, they have a protein rich layer called pellicle which makes their body flexible. |
III: | They have more than two flagella, on all sides of their body. |
IV: | The pigments of euglenoids are identical to those present in higher plants. |
Statement I: | When deprived of sunlight, euglenoids behave like heterotrophs. |
Statement II: | During unfavorable conditions, slime moulds form plasmodium. |
