Question

Match the following:
\begin{tabular}{|c|c|} \hline Table - I & Table - II
\hline A) Diplointic & I) Spirogyra
B) Diplo-bionic & II) Laminaria
C) Haplo-diplontic & III) Polysiphonia
D) Haplontic & IV) Fucus
\hline \end{tabular}
The correct answer is

• A. A-IV, B-I, C-II, D-III
• B. A-III, B-IV, C-II, D-I
• C. A-IV, B-III, C-II, D-I
• D. A-II, B-III, C-IV, D-I

Hint:

When matching life cycles with organisms, always remember the basic classifications of plant life cycles. Diplointic corresponds to those organisms with a dominant diploid phase (like Fucus), while Haplontic and Haplo-diplontic correspond to those with dominant haploid or alternating phases.

Answer 1

The Correct Option is C

Step 1: Understanding life cycle types
- Diplontic (A-IV - Fucus):
- In the diplontic life cycle, the diploid phase (sporophyte) is dominant.
- Fucus follows this type of life cycle.
- Diplo-biontic (B-III - Polysiphonia):
- In the diplo-biontic life cycle, both haploid and diploid phases are prominent.
- Polysiphonia exhibits this type of life cycle.
- Haplo-diplontic (C-II - Laminaria):
- The haplo-diplontic life cycle involves an alternation of generations where both haploid and diploid stages are multicellular.
- Laminaria exhibits this type.
- Haplontic (D-I - Spirogyra):
- In the haplontic life cycle, the haploid stage is dominant, and the diploid phase is short-lived.
- Spirogyra follows this life cycle.
Step 2: Examining the given options
- Option 1 (A-IV, B-I, C-II, D-III) → Incorrect (Mismatch in B and D).
- Option 2 (A-III, B-IV, C-II, D-I) → Incorrect (Mismatch in A and B).
- Option 3 (A-IV, B-III, C-II, D-I) → Correct, as it matches the classification properly.
- Option 4 (A-II, B-III, C-IV, D-I) → Incorrect (Mismatch in A and C).
Step 3: Conclusion Since the correct matching is A-IV, B-III, C-II, D-I, the correct answer is Option (3).
