Question

Identify the correct statement.

NISHANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
**Primary Concept**: Plant Tissue Systems and their functions.
**Related Topics**: Secondary Growth, Vascular Bundle Arrangement, Tissue Repair, Grafting.
**Prerequisites**: Basic knowledge of plant anatomy, especially different tissue types (parenchyma, sclerenchyma, xylem, phloem), their functions, and secondary growth in plants.
## SOLUTION PATHWAY
**Given Information**:
   *  The question tests understanding of plant tissue functions and their role in plant growth/repair
   * The correct answer is provided.
**Method & Steps**:
 1. **Analyze each statement**: Evaluate each statement based on known concepts of plant biology.
   Reasoning: Understanding the typical characteristics of plants and the function of plant tissues is necessary.
 2. **Statement A**: Plants near the sea shore can still experience seasonal changes and produce annual rings. So, this statement is incorrect.
   Reasoning: Annual rings are a result of seasonal variations in xylem production.
 3. **Statement B**: Plant height is influenced by many factors, not only age. It's not a reliable indicator of age.
   Reasoning: Height is impacted by environment, genetics, and other factors.
 4. **Statement C**: Sclerenchyma cells are primarily for support and not involved in tissue repair. Parenchyma cells are involved in healing.
   Reasoning: Parenchyma cells are responsible for regeneration and repair.
 5. **Statement D**: Monocots have scattered vascular bundles, making grafting difficult. Dicots have a ring-like arrangement, aiding grafting.
    Reasoning: Grafting requires vascular cambium contact, which is difficult due to the scattered nature in monocots
**Final step**:
   Result: Statement D is the only correct statement.
   Verification: The provided answer matches the conclusion from the analysis.
## OPTION ANALYSIS
[A] :x: Incorrect. Plants near the seashore can still form annual rings due to seasonal variations.
[B] :x: Incorrect. Plant height is not a reliable indicator of age.
[C] :x: Incorrect. Sclerenchyma provides support, not healing. Parenchyma cells are involved in repair.
[D] ✓: Correct. Scattered vascular bundles in monocots make grafting difficult due to the lack of a continuous cambium layer.
## LEARNING AIDS
**Common Mistakes**:
 1. Confusing sclerenchyma with parenchyma functions: Remember, parenchyma is for repair, while sclerenchyma is for support.
 2. Assuming plant height correlates directly with age: Plant height is affected by many environmental and genetic factors.
**Quick Tips**:
 1. Remember that dicots (with vascular cambium in a ring) are easier to graft than monocots.
 2. Annual rings are caused by seasonal variations in xylem growth, not just location.

NISHANTH · Answer

Because of marked climatic variations, plants growing near the sea shore do not produce annual rings

NISHANTH · Answer

The age of the plant can be determined by its height

NISHANTH · Answer

Healing of damaged tissue is because of the activity of sclerenchyma cells

NISHANTH · Answer

The correct Option is "Grafting is difficult in monocot plants as they have scattered vascular bundles "
