D. Vascular tissue

Answer

To solve the question regarding the characteristics attributed to a specific type of tissue, we can analyze each statement step by step:

### Step-by-Step Solution:

1. **Identify the Major Component within Organs**:
- The first statement mentions that the tissue forms a major component within organs. This is a characteristic of **parenchyma** tissue, which is found in various organs and is essential for their structure and function.

**Hint**: Think about which type of tissue is commonly found throughout different plant organs.

2. **Cell Wall Composition**:
- The second statement indicates that the cell wall is thin and cellulosic. Parenchyma cells are known for having thin cell walls made primarily of cellulose.

**Hint**: Recall the structural features of different plant tissues and their cell wall compositions.

3. **Shape of Cells**:
- The third statement describes the shape of the cells as generally isodiametric, meaning they have equal dimensions in all directions. Parenchyma cells typically have this shape.

**Hint**: Consider the typical morphology of plant cells and how they differ among various tissue types.

4. **Intercellular Space**:
- The fourth statement mentions the presence or absence of intercellular space. Parenchyma cells often have intercellular spaces, allowing for gas exchange and storage.

**Hint**: Think about how cell arrangement affects gas exchange and nutrient storage in plants.

5. **Function of the Tissue**:
- The fifth statement highlights that the tissue can be photosynthetic, storage, or secretory in function. Parenchyma tissue serves multiple functions, including storage (e.g., in fruits) and photosynthesis (e.g., in chlorenchyma, a type of parenchyma containing chlorophyll).

**Hint**: Reflect on the various roles that different plant tissues play in plant physiology.

### Conclusion:
Based on the analysis of all the statements, the characteristics listed are attributed to **parenchyma** tissue.

### Final Answer:
The above characters are attributed to **parenchyma**.
