The correct Answer is:
To solve the question, "Identify the living plant tissues whose main function is to provide buoyancy to the plant," we can follow these steps: ### Step 1: Understand Plant Tissues Plant tissues are generally categorized into two main types: simple tissues and complex tissues. Simple tissues consist of one type of cell, while complex tissues are made up of multiple cell types. **Hint:** Remember the two main categories of plant tissues: simple and complex. ### Step 2: Identify Simple Permanent Tissues The simple permanent tissues include: - Parenchyma - Collenchyma - Sclerenchyma **Hint:** Focus on the characteristics of these simple tissues to determine their functions. ### Step 3: Analyze the Function of Each Tissue - **Parenchyma:** This tissue is living and has various functions, including storage, photosynthesis, and providing buoyancy in aquatic plants due to its large air cavities. - **Collenchyma:** This tissue provides support to growing parts of the plant but does not contribute to buoyancy. - **Sclerenchyma:** This tissue is dead at maturity and provides structural support, so it does not provide buoyancy. **Hint:** Consider which tissues are living and their specific functions related to buoyancy. ### Step 4: Focus on Aquatic Plants In aquatic plants, the parenchyma tissue is modified to form a specialized type called aerenchyma, which contains large air cavities that help the plant float. **Hint:** Look for the specific adaptation in aquatic plants that aids in buoyancy. ### Step 5: Conclusion Based on the analysis, the living plant tissue that provides buoyancy is **parenchyma**, specifically the modified form known as **aerenchyma**. **Final Answer:** The correct answer is **parenchyma**.
