🔍 Summary Explanation:

This cloze activity teaches key concepts about plant importance, photosynthesis, and plant structure:
- Plants produce oxygen and food.
- They use sunlight, carbon dioxide, and water to make sugars via photosynthesis.
- Chlorophyll captures light energy.
- Roots absorb water and minerals; stems transport them.
- Flowers are reproductive organs.

All answers come directly from the word bank and scientific knowledge appropriate for Year 3 Science.
