Explanation:
Detailed explanation-1: -So, the correct answer is, ‘autumn wood’.
Detailed explanation-2: -In autumn wood, the xylem elements i.e. tracheids and vessels are more thickened due to deposition hence narrower compared to springwood. The cambium is more active during the spring and forms xylem vessels with wider cavities referred to as spring wood or earlywood.
Detailed explanation-3: -Fewer xylary elements with narrow vessels. Hint:The vascular cambium tissue which is present between the xylem and phloem of plants causes secondary growth. Secondary growth of xylem results in the formation of springwood and autumn wood. Springwood is produced inwardly and has lighter wide circles.
