What is a key difference between early wood spring wood and late wood summer wood ?
A: Early wood has thick-walled cells that provide more support, while late wood has large-diameter cells for water transport.
B: Early wood is produced in dry seasons and late wood in wet seasons.
C: Early wood consists of cells with large diameters and thin walls, maximizing water delivery, whereas late wood has thick-walled cells providing more support.
D: Late wood contains vessel elements, while early wood only contains tracheids.
Explanation
Early wood, formed in spring when water is abundant, has cells with large diameters and thin walls, optimizing water transport. Late wood, formed later in the growing season, has smaller, thick-walled cells that provide structural support.
