Q.23 Match List I with List II
| LIST I | LIST II |
|---|---|
| A. Lutoids | I. Sieve elements |
| B. Nacre wall | II. Idioblast |
| C. Cystolith | III. Cork cambium |
| D. Phelloid cell | IV. Laticifers |
Choose the correct answer from the options given below:
- A-II, B-IV, C-III, D-I
- A-IV, B-I, C-II, D-III
- A-I, B-III, C-IV, D-II
- A-III, B-II, C-I, D-IV
Lutoids are organelles in laticifers, cystoliths form in idioblasts (lithocysts), cystoliths are calcium carbonate deposits in specialized cells, and phelloid cells are non-suberized cells in cork cambium (periderm).
The correct option is A-IV, B-I, C-II, D-III.
Question Breakdown
This matching tests plant anatomy terms with their associations, focusing on cell types and structures.
-
List I: Terms (A. Lutoids, B. Nacre wall, C. Cystolith, D. Phelloid cell).
-
List II: Associations (I. Sieve elements, II. Idioblast, III. Cork cambium, IV. Laticifers).
Correct Matches
Term Matches Explanation [Citation] A. Lutoids IV. Laticifers Vacuolar organelles in latex-producing laticifers of Hevea (rubber). B. Nacre wall I. Sieve elements Mother-of-pearl-like callose wall on sieve plates in phloem sieve elements. C. Cystolith II. Idioblast Calcium carbonate crystals in lithocysts (specialized idioblasts). D. Phelloid cell III. Cork cambium Non-suberized cells produced by phellogen (cork cambium) in periderm. Option Analysis
-
A-II, B-IV, C-III, D-I: Wrong; Lutoids not idioblasts, nacre wall not laticifers.
-
A-IV, B-I, C-II, D-III: Correct, as per table.
-
A-I, B-III, C-IV, D-II: Wrong; mismatches all—lutoids not sieve elements.
-
A-III, B-II, C-I, D-IV: Wrong; phelloid not laticifers, cystolith not sieve.
Article Introduction
Ace your Match List I with List II on Lutoids, Nacre wall, Cystolith, and Phelloid cell in plant anatomy for NEET or botany exams. Discover the right pairing—A-IV (Laticifers), B-I (Sieve elements), C-II (Idioblast), D-III (Cork cambium)—with in-depth explanations of these specialized plant structures to excel in phloem, periderm, and cell inclusions topics.Key Concepts
These terms relate to plant cell specialization for latex, transport, protection, and storage.
-
Lutoids: Lysosome-like bodies in laticifer cytoplasm aiding latex coagulation.
-
Nacre wall: Shiny callose layer in sieve elements preventing phloem plugging.
-
Cystolith: CaCO₃ in epidermal idioblasts (lithocysts) for defense/calcium storage.
-
Phelloid cell: Thin-walled cells from cork cambium, unlike suberized cork.
Exam Tips
Focus on associations: Lutoids with latex cells, cystoliths with crystals/idioblasts. Practice similar matchings for secondary growth and vascular tissues.
