9 Best Worksheets For Exploring The Wonders Of Photosynthesis ... - Free Printable

Let's solve the fill-in-the-blanks exercise on "The Process of Photosynthesis" step by step. Here is the completed version with explanations for each answer.

---

1. Photosynthesis is the process by which plants make their own ________.

✔ Answer: *food*

🔹 Explanation:
Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose (a type of sugar), which serves as food for the plant.

---

2. Plants use ________, ________, and ________ to produce glucose and oxygen.

✔ Answer: *water, carbon dioxide, sunlight*

🔹 Explanation:
The raw materials for photosynthesis are:
- Water (H₂O) – absorbed from the soil through roots.
- Carbon dioxide (CO₂) – taken in from the air through stomata.
- Sunlight – captured by chlorophyll in the leaves.

These are used to produce glucose (C₆H₁₂O₆) and oxygen (O₂) as byproducts.

3. The green substance called ________ helps in absorbing sunlight.

✔ Answer: *chlorophyll*

🔹 Explanation:
Chlorophyll is the green pigment found in chloroplasts of plant cells. It absorbs light energy, especially red and blue wavelengths, and converts it into chemical energy during photosynthesis.

---

4. The small pores called ________ help in absorbing carbon dioxide.

✔ Answer: *stomata*

🔹 Explanation:
Stomata (singular: stoma) are tiny openings on the surface of leaves that allow gas exchange. They open to let carbon dioxide enter and oxygen exit during photosynthesis.

---

5. The ________ helps in controlling the rate of transpiration.

✔ Answer: *guard cells*

🔹 Explanation:
Guard cells surround each stoma and regulate its opening and closing. When guard cells swell with water, the stoma opens; when they lose water, the stoma closes. This controls transpiration (loss of water vapor) and also affects CO₂ intake.

---

6. Water is transported from the roots to the stem and leaves via the ________.

✔ Answer: *xylem*

🔹 Explanation:
The xylem is a vascular tissue in plants responsible for transporting water and dissolved minerals from the roots upward to the stems and leaves. This movement is driven by transpiration pull and root pressure.

---

✔ Final Answers:

1. food
2. water, carbon dioxide, sunlight
3. chlorophyll
4. stomata
5. guard cells
6. xylem
