Options

A. Synonyms of phellem
B. Lignified cork cells
C. Suberized cork cells
D. Non-suberzed cork cells

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Phallum":**
- Phallum refers to a type of protective tissue in plants, specifically the cork tissue.
- It is composed of non-living cells that provide protection to the plant.

2. **Composition of Phallum:**
- The walls of phallum cells contain a substance called subarin, which contributes to their protective qualities.

3. **Defining Phalloids:**
- Phalloids are essentially cork-like cells that are similar to phallum but have a key difference.
- They lack subarin in their cell walls, which distinguishes them from phallum.

4. **Analyzing the Options:**
- Option 1: Synonyms of phallum - This is correct because phalloids can be considered a type of phallum, but with the absence of subarin.
- Option 2: Lignified coccyx - This is incorrect as it does not relate to the definition of phalloids.
- Option 3: Subarised coccyx - This is incorrect because phalloids do not contain subarin.
- Option 4: Non-subarised coccyx - This is partially correct but does not capture the essence of phalloids being synonymous with phallum.

5. **Conclusion:**
- The correct answer is that phalloids are synonymous with phallum, with the distinction that they lack subarin in their walls.

**Final Answer:**
Phalloids are synonymous with phallum, but they lack subarin in their walls.
