Go through the following statements
(i) Phloem parenchya is absent in most of the monocot
(ii) Phloem fibres store food material and other substance like resins, latex and mucilage
(iii) Phloem fibre are generally absent in the primary phloem but are found in the secndary phloem
(iv) Gymnosperms lack sieve tubes and albuminous cells.
Which of these are correct ?

Options

A. (i), (ii) and (iii)
B. (ii), (iii) and (iv)
C. (i) and (iii)
D. (i), (iii) and (iv)

Answer

To determine which of the statements regarding phloem and gymnosperms are correct, we will analyze each statement step by step.

### Step 1: Analyze Statement (i)
**Statement:** Phloem parenchyma is absent in most of the monocots.

**Analysis:**
Phloem parenchyma is a type of tissue found in the phloem that is responsible for storing food. In monocots, phloem parenchyma is indeed present, although it may be less prominent compared to dicots. Therefore, this statement is **incorrect**.

### Step 2: Analyze Statement (ii)
**Statement:** Phloem fibers store food material and other substances like resins, latex, and mucilage.

**Analysis:**
Phloem fibers primarily provide mechanical support to the phloem rather than storing food. The storage of food is mainly the function of phloem parenchyma. Thus, this statement is also **incorrect**.

### Step 3: Analyze Statement (iii)
**Statement:** Phloem fibers are generally absent in the primary phloem but are found in the secondary phloem.

**Analysis:**
This statement is **correct**. Phloem fibers typically do not develop in the primary phloem; they are more commonly found in the secondary phloem, which forms during secondary growth.

### Step 4: Analyze Statement (iv)
**Statement:** Gymnosperms lack sieve tubes and albuminous cells.

**Analysis:**
Gymnosperms do lack sieve tubes; instead, they have sieve cells for the conduction of food. However, they do have albuminous cells, which are similar in function to companion cells found in angiosperms. Therefore, this statement is **incorrect**.

### Conclusion
Based on the analysis:
- Statement (i) is incorrect.
- Statement (ii) is incorrect.
- Statement (iii) is correct.
- Statement (iv) is incorrect.

Thus, the correct statements are **(iii)** only.

### Final Answer
The correct statements are: **(iii) only.**
