A mature corn plant absorbs almost …...of…... water in ...

Options

A. 5 litres ,in a day
B. 1 litres ,one hour
C. 5 litres in a half day
D. 3 litres , a day

Answer

To solve the question regarding how much water a mature corn plant absorbs, we can follow these steps:

### Step 1: Understand the Question
The question asks how much water a mature corn plant absorbs in a given time frame. We need to identify the correct quantity of water absorbed per day.

### Step 2: Analyze the Options
The options provided are:
- A) 5 liters in a day
- B) 1 liter in 1 hour
- C) 5 liters in a half day
- D) 3 liters a day

### Step 3: Consider Plant Water Relationships
Plants, including corn, require water for various metabolic activities, including nutrient transport and photosynthesis. Transpiration also plays a significant role in water loss.

### Step 4: Focus on Mature Corn Plants
Research indicates that mature corn plants typically absorb a significant amount of water daily.

### Step 5: Evaluate Each Option
- **Option A (5 liters in a day)**: This is likely too high for a mature corn plant.
- **Option B (1 liter in 1 hour)**: This would amount to 24 liters in a day, which is excessive.
- **Option C (5 liters in a half day)**: This would also be too high, equating to 10 liters in a full day.
- **Option D (3 liters a day)**: This is consistent with the known absorption rates for mature corn plants.

### Step 6: Conclusion
The correct answer is **D) 3 liters a day**.
