#### Part 1: Matching Plant Needs to Plant Parts

We are asked to match each plant need with the part of the plant that helps meet that need.

Here’s how they connect:

1. Water → Root
- The roots absorb water from the soil and transport it upward through the plant.

2. Air → Leaf
- Leaves take in carbon dioxide (a component of air) during photosynthesis, and exchange gases (CO₂ and O₂) through tiny openings called stomata.

3. Minerals → Root
- Roots absorb essential minerals and nutrients from the soil, which are dissolved in water.

4. Sunlight → Leaf
- Leaves contain chlorophyll, which captures sunlight for photosynthesis.

5. Reproduction → Flowers
- Flowers are the reproductive structures of plants; they produce seeds and help in pollination.

#### Matching Summary:

| Plant Need | Plant Part |
|----------------|---------------|
| Water | Root |
| Air | Leaf |
| Minerals | Root |
| Sunlight | Leaf |
| Reproduction | Flowers |

#### Part 2: Answering the Questions

1. How do roots help a plant survive?
Roots help a plant survive by:
- Absorbing water and minerals from the soil.
- Anchoring the plant firmly in the ground.
- Storing food in some plants (like carrots or beets).

✔ Answer:
*Roots help a plant survive by absorbing water and minerals from the soil and anchoring the plant in place.*

2. Why do plants need sunlight?
Plants need sunlight to perform photosynthesis, the process by which they make their own food. During photosynthesis:
- Sunlight is used to convert carbon dioxide (from the air) and water (from the soil) into glucose (food) and oxygen.

✔ Answer:
*Plants need sunlight to make their own food through photosynthesis.*

---

✔ Final Answer Key:

Matching:
- Water → Root
- Air → Leaf
- Minerals → Root
- Sunlight → Leaf
- Reproduction → Flowers

Written Answers:
- How do roots help a plant survive?
Roots absorb water and minerals from the soil and anchor the plant in place.

- Why do plants need sunlight?
Plants need sunlight to make their own food through photosynthesis.
