The correct Answer is:
To determine which statement is not true regarding plant growth and development, we will analyze each option step by step. ### Step 1: Analyze the First Statement **Statement:** Growth is restricted to living cells. - **Explanation:** This statement is true. Growth in plants occurs in living cells where metabolic processes take place. Non-living cells do not exhibit growth. ### Step 2: Analyze the Second Statement **Statement:** The increased size of the dry seed soaked in water is the outcome of growth. - **Explanation:** This statement is not true. When a dry seed is soaked in water, it absorbs water and becomes turgid due to the process of imbibition, which is the absorption of water by the seed. This increase in size is not due to growth (cell division and expansion) but rather due to the physical absorption of water. ### Step 3: Analyze the Third Statement **Statement:** Growth is accomplished by metabolism. - **Explanation:** This statement is true. Growth in plants is indeed a result of metabolic processes, including respiration and photosynthesis, which provide the energy and materials necessary for growth. ### Step 4: Analyze the Fourth Statement **Statement:** The positive force of cell growth is turgor pressure. - **Explanation:** This statement is true. Turgor pressure, which is the pressure of the cell contents against the cell wall, is a significant factor in plant cell growth. It helps maintain cell shape and supports the plant structure. ### Conclusion After analyzing all the statements, we find that the second statement is the one that is not true. **Final Answer:** The statement that is not true is: "The increased size of the dry seed soaked in water is the outcome of growth." ---
