Which one of the statements is correct ?

Options

A. Leaves of conifers are perennial
B. All vascular plants have Sieve Tube Members
C. The red and edible flesh of strawberry is the carpel tissue
D. Conifers have motile gametes.

Answer

To determine which statement is correct, we will analyze each of the provided options step by step.

### Step 1: Analyze the first statement
**Statement:** Leaves of conifers are perennial.

- **Explanation:** Conifers, such as pines and firs, have needle-like leaves that are adapted to withstand harsh conditions. These leaves are indeed perennial, meaning they can last for several years (typically 3 to 8 years) before falling off. This statement is correct.

### Step 2: Analyze the second statement
**Statement:** All vascular plants have sieve tube members.

- **Explanation:** Sieve tube members are specialized cells found in the phloem of flowering plants (angiosperms). However, not all vascular plants possess these structures. For example, gymnosperms (like conifers) do not have sieve tube members. Therefore, this statement is incorrect.

### Step 3: Analyze the third statement
**Statement:** The red and edible flesh of a strawberry is a carpal.

- **Explanation:** The edible part of a strawberry is actually derived from the thalamus (the thickened part of the stem) and is classified as a false fruit. The carpal refers to the ovary of the flower, which is not the fleshy part we eat. Thus, this statement is incorrect.

### Step 4: Analyze the fourth statement
**Statement:** Conifers have multi-gamete.

- **Explanation:** This statement is misleading. Conifers produce male and female gametes, but they do not have multi-gamete structures. The male gametes (pollen) are non-motile, and the female gametes are contained within the ovules. Therefore, this statement is also incorrect.

### Conclusion
After analyzing all the statements, the only correct statement is:
- **Leaves of conifers are perennial.**

### Final Answer
The correct statement is: **Leaves of conifers are perennial.**
