Sure! If you’re preparing for a 7th-grade science unit test on plants, I can help you with some sample questions and key concepts you might want to study. Here are some categories of questions that could be relevant:
### Sample Questions:
#### Multiple Choice:
1. **What is the process by which plants make their own food using sunlight?**
a) Respiration
b) Photosynthesis
c) Transpiration
d) Germination
2. **Which part of the plant is responsible for absorbing water and nutrients?**
a) Stem
b) Leaf
c) Root
d) Flower
3. **Which of the following is NOT a type of plant tissue?**
a) Xylem
b) Phloem
c) Dermal
d) Nervous
4. **What is the main function of the stomata in leaves?**
a) To support the plant structure
b) To exchange gases
c) To store water
d) To anchor the plant
#### True or False:
5. **True or False: All plants reproduce sexually by producing seeds.**
6. **True or False: Angiosperms are plants that produce flowers.**
#### Short Answer:
7. **Describe the role of chlorophyll in photosynthesis.**
8. **List the three main parts of a flower and their functions.**
#### Fill in the Blanks:
9. **In the process of photosynthesis, plants take in __________ and release __________.**
10. **The male reproductive part of a flower is called the __________.**
### Key Concepts to Study:
1. **Photosynthesis:** Understand the process, equation (6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂), and the role of chlorophyll.
2. **Plant Structures:** Know the functions of roots, stems, leaves, flowers, and fruits.
3. **Plant Classification:** Be familiar with the differences between angiosperms (flowering plants) and gymnosperms (non-flowering plants).
4. **Reproduction in Plants:** Study both sexual reproduction (seeds, pollination) and asexual reproduction (cuttings, runners).
5. **Plant Processes:** Learn about transpiration, respiration, and nutrient uptake.
6. **Plant Adaptations:** Recognize how plants adapt to their environments, such as xerophytes in deserts.
7. **Life Cycle of Plants:** Understand the stages of a plant life cycle from seed germination to maturity.
### Tips for Test Preparation:
- Review your notes and textbook sections on plants.
- Use flashcards to memorize key terms and definitions.
- Participate in group study sessions to quiz each other.
- Take practice tests if available.
If you have specific topics you want to focus on or need more examples, let me know! Good luck on your test!
