Let's solve the fill-in-the-blanks exercise on
"The Process of Photosynthesis" step by step. We are given a list of words to choose from:
Word Bank:
- water
- carbon dioxide
- food
- transpiration
- process
- xylem
- phloem
- sunlight
- guard cells
- stomata
- chlorophyll
Now, let’s go through each question and determine the correct answer.
---
1. Photosynthesis is the process by which plants make their own _________.
- Plants produce their own food through photosynthesis.
-
✔ Answer: food
---
2. Plants use _________, __________ and __________ to produce glucose and oxygen.
- The raw materials for photosynthesis are:
- Carbon dioxide (from the air)
- Water (from the soil)
- Sunlight (energy source)
- These are used to make glucose and oxygen.
-
✔ Answer: carbon dioxide, water, sunlight
*(Note: Order may vary, but these three are required.)*

3. The green substance called _________ helps in absorbing sunlight.
- Chlorophyll is the green pigment in plant cells that captures light energy.
-
✔ Answer: chlorophyll
---
4. The small pores called _________ help in absorbing carbon dioxide.
- Stomata are tiny openings on the leaf surface that allow gas exchange (CO₂ enters, O₂ exits).
-
✔ Answer: stomata
---
5. The _________ helps in controlling the rate of transpiration.
- Guard cells surround the stomata and open or close them, regulating water loss (transpiration).
-
✔ Answer: guard cells
---
6. Water is transported from the roots to the stem and leaves via the _________.
- Xylem is the vascular tissue responsible for transporting water and minerals upward from roots to leaves.
-
✔ Answer: xylem
---
✔ Final Answers:
1.
food
2.
carbon dioxide, water, sunlight
3.
chlorophyll
4.
stomata
5.
guard cells
6.
xylem

🌿 Summary of Key Concepts:
-
Photosynthesis: A biological process where plants convert light energy into chemical energy.
-
Equation:
Carbon dioxide + Water + Sunlight → Glucose + Oxygen
-
Chlorophyll captures light.
-
Stomata allow CO₂ entry and O₂ exit.
-
Guard cells regulate stomatal opening.
-
Xylem transports water;
phloem transports food (glucose).
