Which of the following statements is false?

Options

A. Stems and leaves depend on the water and minerals absorbed by the roots.
B. Roots depend upon sugars produced in photosynthetic organs such as leaves.
C. Plant roots absorb carbon dioxide needed for photosynthesis from the soil.
D. The terminal bud in many plants produces hormones that inhibit growth in the axillary buds

Answer

To determine which statement is false, let's analyze each option step by step:

1. **Option 1: "Stems and leaves depend on the water and minerals absorbed by the roots."**
- **Analysis:** This statement is true. Roots absorb water and minerals from the soil, which are then transported to the stems and leaves for growth and photosynthesis.

2. **Option 2: "Roots depend upon sugar produced in the photosynthetic organs such as leaves."**
- **Analysis:** This statement is also true. The leaves perform photosynthesis and produce glucose, which is then transported to the roots in the form of sucrose. The roots rely on this sugar for energy and growth.

3. **Option 3: "Plant roots absorbed carbon dioxide did it for photosynthesis from the soil."**
- **Analysis:** This statement is false. In photosynthesis, carbon dioxide is absorbed from the air, not from the soil. The roots do not absorb carbon dioxide; they primarily absorb water and minerals.

4. **Option 4: "Terminal bud in a plant produces hormone that inhibits the growth of axillary bud."**
- **Analysis:** This statement is true. The terminal bud (apical bud) produces auxin, a plant hormone that inhibits the growth of axillary buds, promoting apical dominance.

**Conclusion:** The false statement is **Option 3**.
