To determine the correctness of the statements, let's analyze each one:
Statement I: Parenchyma is living but collenchyma is dead tissue.
Analysis: Parenchyma is indeed a living tissue found in plants and is known for storage and metabolic functions. On the other hand, collenchyma is also a living tissue, providing support with flexibility in growing parts of the plant. Therefore, this statement is false because both parenchyma and collenchyma are living tissues.
Statement II: Gymnosperms lack xylem vessels but presence of xylem vessels is the characteristic of angiosperms.
Analysis: Gymnosperms generally lack xylem vessels; instead, they have tracheids that aid in water transport. Angiosperms, however, possess xylem vessels, which are specialized for efficient water transport. This statement is true.
Based on the analyses, the correct answer is that Statement I is false, but Statement II is true. Hence, the correct option is:
Statement I is false but Statement II is true
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
