Text Solution

AI Generated Solution

### Step-by-Step Text Solution: 1. **Understanding the Statement**: The statement claims that diffusion is the only means for gaseous movement within the plant body. This implies that no other mechanisms, such as active transport or bulk flow, are involved in the movement of gases. 2. **Lack of Circulatory System**: Plants do not possess a circulatory system like animals. This means there are no blood vessels or specialized fluids to transport gases and nutrients throughout the plant body. 3. **Gaseous Exchange**: Plants need to exchange gases, primarily oxygen and carbon dioxide, for processes like photosynthesis and respiration. This exchange occurs at the cellular level. ...
