Select the incorrect statement.

A

Phloem of gymnosperms have albuminous cells and sieve cells

B

Initiation of lateral roots and vascular cambium during the secondary growth takes place in pericycle

C

The abaxially placed palisade parenchyma in a dicot leaf is made up of elongated cell , which are arranged vertically and parallel to each other.

D

The cambial ring in dicot stem cuts off new cells, those cut off towards pith. Mature into secondary xylem and the cells cut off towards periphery mature into secondary phloem.

The correct Answer is:
To solve the question, "Select the incorrect statement," we need to analyze each of the provided options carefully. Here’s a step-by-step breakdown of the solution: ### Step 1: Analyze the First Statement **Statement:** The phloem of angiosperms has agglutinous cells and sieve cells. **Analysis:** This statement is incorrect because angiosperms have sieve tube elements and companion cells, not agglutinous cells and sieve cells. Therefore, this statement is true. ### Step 2: Analyze the Second Statement **Statement:** The initiation of the lateral root and the vascular cambium during secondary growth takes place in the pericycle. **Analysis:** This statement is correct. The pericycle is indeed the layer from which lateral roots and vascular cambium originate during secondary growth. ### Step 3: Analyze the Third Statement **Statement:** The abaxially placed parenchyma in dicot leaf is made up of elongated cells which are arranged vertically and parallel to each other. **Analysis:** This statement is incorrect. The abaxial side of a dicot leaf contains spongy mesophyll cells, which are not elongated and arranged vertically. Instead, the palisade mesophyll cells are found on the adaxial side. Therefore, this statement is false. ### Step 4: Analyze the Fourth Statement **Statement:** The cambial ring in dicot stem cuts off new cells, and those cut off towards the pith mature into secondary xylem, while those cut off towards the periphery become secondary phloem. **Analysis:** This statement is correct. The cambial ring does produce secondary xylem towards the pith and secondary phloem towards the periphery. ### Conclusion After analyzing all four statements, we find that the incorrect statement is **Option 3**: "The abaxially placed parenchyma in dicot leaf is made up of elongated cells which are arranged vertically and parallel to each other." ### Final Answer **The incorrect statement is Option 3.** ---
