How Water Travels Through a Plant (Year 3) | CGP Plus - Free Printable

Problem Analysis:

The task involves understanding how water is transported in a plant and correcting statements related to this process. Let's break it down step by step.

#### Part 1: Adding Arrows to Show Water Transport
The image shows a plant with roots, a stem, leaves, and flowers. The task is to add arrows indicating the direction of water movement through the plant. One arrow has already been provided (likely pointing upward from the roots).

- Correct Direction of Water Movement:
- Water enters the plant through the roots.
- It travels upward through the stem.
- It reaches the leaves and flowers.
- Excess water is released into the atmosphere through the leaves via transpiration.

Thus, the arrows should point:
1. From the soil into the roots.
2. Upward from the roots through the stem.
3. To the leaves and flowers.

#### Part 2: Identifying the Correct Sentence
Four sentences are provided, and only one is correct. Let’s analyze each:

1. "Plants take in water through their leaves."
- Incorrect: Plants primarily absorb water through their roots, not their leaves. Leaves are involved in transpiration (water loss), but they do not actively take in water.

2. "Water travels through a plant's flowers before it goes through the stem."
- Incorrect: Water first travels through the stem and then reaches the flowers. Flowers are at the top of the plant and receive water that has already traveled up the stem.

3. "A plant's roots take in water from the soil."
- Correct: Roots have specialized structures called root hairs that absorb water and nutrients from the soil. This is the primary way plants obtain water.

4. "Water travels down a plant's stem to the roots."
- Incorrect: Water moves upward through the stem, not downward. The upward movement is driven by transpiration pull (evaporation of water from leaves) and capillary action.

#### Part 3: Writing Correct Versions of the Wrong Sentences
For the three incorrect sentences, we need to rewrite them correctly:

1. Original: "Plants take in water through their leaves."
- Corrected: "Plants take in water through their roots."

2. Original: "Water travels through a plant's flowers before it goes through the stem."
- Corrected: "Water travels through a plant's stem before it reaches the flowers."

3. Original: "Water travels down a plant's stem to the roots."
- Corrected: "Water travels up a plant's stem to the leaves and flowers."

Final Answer:

1. Arrows for Water Transport:
- Add arrows pointing:
- From the soil into the roots.
- Upward from the roots through the stem.
- To the leaves and flowers.

2. Correct Sentence:
- Tick the box next to: "A plant's roots take in water from the soil."

3. Corrected Versions of Incorrect Sentences:
- "Plants take in water through their leaves." → "Plants take in water through their roots."
- "Water travels through a plant's flowers before it goes through the stem." → "Water travels through a plant's stem before it reaches the flowers."
- "Water travels down a plant's stem to the roots." → "Water travels up a plant's stem to the leaves and flowers."

Final Boxed Answer:
\[
\boxed{
\text{1. Add arrows as described.}
\text{2. Tick: "A plant's roots take in water from the soil."}
\text{3. Corrected sentences:}
\text{- Plants take in water through their roots.}
\text{- Water travels through a plant's stem before it reaches the flowers.}
\text{- Water travels up a plant's stem to the leaves and flowers.}
}
