To solve this problem, we need to analyze the given statements about springwood and identify the correct set of statements. Let's evaluate each statement:$\newline \bullet$(a) It is also called the earlywood:$\newline$ - Springwood is indeed referred to as earlywood because it is formed during the spring season when growth is rapid.$\newline$ - This statement is correct.$\newline \bullet$(b) In spring season, cambium produces xylem elements with narrow vessels:$\newline$ - In the spring season, the cambium is active and produces xylem elements with larger vessels to facilitate efficient water transport.$\newline$ - This statement is incorrect.$\newline \bullet$(c) It is lighter in color:$\newline$ - Springwood is lighter in color compared to autumnwood due to the larger size of the vessels and less dense structure.$\newline$ - This statement is correct.$\newline \bullet$(d) The springwood along with autumnwood shows alternate concentric rings forming annual rings:$\newline$ - The combination of springwood and autumnwood forms the annual rings, which are used to determine the age of a tree.$\newline$ - This statement is correct.$\newline \bullet$(e) It has lower density:$\newline$ - Springwood has a lower density compared to autumnwood due to the larger vessel size and less compact structure.$\newline$ - This statement is correct.$\newline$Now, let's identify the correct set of statements:$\newline$Option 2: (a), (c), (d) and (e) Only$\newline$This corresponds to the correct option, which is Option 2.
