The correct Answer is:
To solve the question regarding which of the options does not produce secondary tissues, let's analyze each option step by step. ### Step 1: Understand Secondary Tissues Secondary tissues are produced by the lateral meristems in plants, which include the vascular cambium and cork cambium (phellogen). These tissues contribute to the growth in thickness of the plant. ### Step 2: Analyze Each Option - **a) Fascicular cambium**: This is a type of cambium located between the xylem and phloem in vascular bundles. It is responsible for producing secondary xylem and phloem, thus it does produce secondary tissues. - **b) Interfascicular cambium**: This cambium forms in the regions between vascular bundles and also contributes to the formation of secondary xylem and phloem. Therefore, it also produces secondary tissues. - **c) Apical meristem**: This is located at the tips of roots and shoots and is responsible for primary growth (lengthening of the plant). It does not produce secondary tissues, as it is involved in the formation of primary tissues. - **d) Phellogen**: Also known as cork cambium, it produces the outer protective layer of the plant (cork) and contributes to secondary growth. Thus, it does produce secondary tissues. ### Conclusion The correct answer is **c) Apical meristem**, as it does not produce secondary tissues. ### Final Answer **c) Apical meristem** ---
