The correct Answer is:
To solve the question regarding the life cycle of acellular slime molds, we will analyze each statement provided and determine which ones are correct. ### Step-by-Step Solution: 1. **Statement A: Haploid vegetative stage is myxamoebae.** - This statement is **incorrect**. Myxamoebae are not the vegetative stage; they are the spores released from the slime mold. 2. **Statement B: Diploid vegetative stage is plasmodium.** - This statement is **correct**. The vegetative stage of acellular slime molds is indeed the plasmodium, which is a multinucleate structure containing diploid nuclei. 3. **Statement C: Capillitium.** - This statement is **correct**. Capillitium refers to a mass of sterile fibers found within the fruiting body of slime molds, which is a characteristic feature. 4. **Statement D: Photosynthetic protists.** - This statement is **incorrect**. Acellular slime molds do not perform photosynthesis; they feed on organic matter. 5. **Statement E: Sporic meiosis.** - This statement is **correct**. Acellular slime molds undergo sporic meiosis, which is a type of reductional division. 6. **Statement F: Isogamous sexual reproduction.** - This statement is **correct**. Isogamous reproduction means that the male and female gametes are similar in appearance, which is true for acellular slime molds. 7. **Statement G: Anisogamous sexual reproduction with zygotic meiosis.** - This statement is **incorrect**. Acellular slime molds exhibit isogamous reproduction, not anisogamous, and they undergo sporic meiosis, not zygotic meiosis. ### Conclusion: The correct set of features regarding the life cycle of acellular slime molds includes: - B (Diploid vegetative stage as plasmodium) - C (Capillitium) - E (Sporic meiosis) - F (Isogamous sexual reproduction) Thus, the correct answer is **B, C, E, and F**.
