Autumn wood can be differentiated from spring wood by

• A. Broad vessels and tracheids
• B. Narrow vessels and tracheids
• C. Red colour of xylem
• D. Cambium

Answer 1

The correct option is B Narrow vessels and tracheids

Early wood or spring wood is formed during spring season. It is formed early in a year. It consists of xylem tissues with wider vessels. They are produced more in amount, less dense.

Late wood or autumn wood is formed during winter season. It is formed after the early wood. It consists of xylem elements with narrow vessels. They are produced less in amount, more dense. They are stronger than early wood, due to larger volume of wall materials.
