Answer-D
Correct Matching:
| List-I | List-II | Explanation |
|---|---|---|
| (A) Chrysophytes | (III) Diatom | 🟢 Diatoms are chrysophytes. Their cell walls contain silica, forming beautiful microscopic shells. |
| (B) Dinoflagellates | (I) Gonyaulax | 🟢 Gonyaulax is a dinoflagellate. Some species cause red tides. |
| (C) Euglenoids | (II) Euglena | 🟢 Euglena is a typical euglenoid. It is photosynthetic in sunlight but can behave heterotrophically in the absence of sunlight. |
| (D) Slime moulds | (IV) Plasmodium | 🟢 Plasmodium is the multinucleate, wall-less feeding stage of slime moulds. |
⭐ Important: Plasmodium
Here, plasmodium ≠ malaria parasite.
Slime mould → plasmodial stage → fruiting bodies → spores
The plasmodium is a multinucleate mass of protoplasm that feeds on decaying organic matter.
⚠️ NEET confusion:
- 🟢 Plasmodium (slime mould stage) → multinucleate feeding stage
- 🔴 Plasmodium (protozoan) → parasite causing malaria
✅ Final Answer
A → III B → I C → II D → IV
🧠 Quick Revision: Diatom → Chrysophyte | Gonyaulax → Dinoflagellate | Euglena → Euglenoid | Plasmodium → Slime mould stage
