Saprophytic protists are:
| 1. | Slime moulds | 2. | Dinoflagellates |
| 3. | Chrysophytes | 4. | Protozoans |
Identify the incorrectly matched pair:
1. Diatoms: Chief producers in oceans
2. Dinoflagellates: Red tides
3. Slime moulds: Spores dispersed by water
4. Euglenoids: Protein rich pellicle
Match each item in Column I with one in Column II and select your answer from the codes given below:
| Column I | Column II | ||
| A. | Diatoms | a. | Protein-rich layer of pellicle |
| B. | Dinoflagellates | b. | Cell wall embedded with silica |
| C. | Euglenoids | c. | Spores with true walls |
| D. | Slime moulds | d. | Cellulose plates in the cell wall |
Codes:
| A | B | C | D | |
| 1. | b | a | c | d |
| 2. | b | d | a | c |
| 3. | b | c | a | d |
| 4. | b | a | d | c |
Slime moulds aren't/haven't
1. Extremely resistant
2. Having spores which are dispersed by air currents
3. An aggregation called as plasmodium
4. Photoautotrophs
The thalloid body of a slime mould (Myxomycetes) is known as:
1. protonema
2. Plasmodium
3. fruiting body
4. mycelium
Select incorrect statement with respect to the following group
of organisms and their characteristics
1. Chrysophyte – Includes diatoms and
desmids, Planktonic
organism.
2. Dinoflagellate – Mostly marine and
photosynthetic, cell wall has
stiff cellulosic plate
on outer surface.
3. Euglenoids – Majority of them are fresh
water, cell wall is absent.
4. Slime mould – Saprophytic motile spores
with true walls
Choose the odd one out with respect to slime moulds
| 1. | Spores possess true cellulosic walls |
| 2. | The body moves along decaying twigs and leaves engulfing organic material |
| 3. | Can grow and spread over several feets |
| 4. | Spores are dispersed by water currents |
