In conifers fibers are likely to be absent in

• A) Secondary Phloem
• B) Secondary Xylem
• C) Primary Phloem
• D) Leaves

In conifers, fibers are typically absent in the Secondary Phloem. This is because conifers primarily rely on tracheids for water conduction and support, rather than fibers, which are more common in angiosperms. Here’s a brief overview of the options:

Understanding the Options

• Secondary Phloem: Lacks fibers in conifers, focusing on sieve elements and companion cells.
• Secondary Xylem: Contains tracheids and may have some fibers, but not as predominant as in angiosperms.
• Primary Phloem: Present in young plants, but fibers are not a significant feature.
• Leaves: Primarily involved in photosynthesis, not in the conduction of water or nutrients.

Thus, the correct answer is A) Secondary Phloem.
