The correct Answer is:
To determine which features belong to xylem parenchyma, let's analyze each statement step by step. ### Step 1: Analyze Statement I - **Statement I**: "Cells are living and thin-walled and their cell walls are made up of cellulose." - Xylem parenchyma is a type of parenchyma tissue. Parenchyma cells are indeed living cells, characterized by thin walls made of cellulose. Therefore, this statement is true for xylem parenchyma. ### Step 2: Analyze Statement II - **Statement II**: "They store food material." - One of the primary functions of xylem parenchyma is to store food materials, particularly starch and other nutrients. Thus, this statement is also true for xylem parenchyma. ### Step 3: Analyze Statement III - **Statement III**: "The radial conduction of water in plants takes place by the help of these tissues." - While xylem as a whole is responsible for the conduction of water in plants, the radial conduction specifically refers to the movement of water through the xylem vessels and tracheids. Xylem parenchyma does play a supportive role in water conduction, but it is not primarily responsible for it. Therefore, this statement is somewhat misleading. However, xylem parenchyma does assist in the overall function of the xylem. ### Conclusion Based on the analysis: - Statement I is true for xylem parenchyma. - Statement II is true for xylem parenchyma. - Statement III is somewhat true but not the primary function of xylem parenchyma. Thus, all three statements can be associated with xylem parenchyma, making the correct answer that all features belong to xylem parenchyma. ### Final Answer All three statements (I, II, and III) belong to xylem parenchyma.
