Student Worksheet: The Plant Life Cycle
Teacher Note: Students can watch the video lesson above and answer the questions. Click the “Teacher Answer Key” dropdown below when you are ready to review the solutions!
Key Concepts:
• Seed: A tiny baby plant resting inside a seed coat; it needs water and warmth to wake up.
• Germination: Germination means sprouting — the first root grows down into the soil, and the stem grows up toward the light.
• Growth: The plant grows leaves and gets bigger, using sunlight, water, air, and space.
• Mature Plant: The plant grows flowers, which help make new seeds, and the life cycle repeats.
Instructions: Read each question carefully and write your answer in the space provided.
- Question 1: What are the four stages of the plant life cycle, in order?
- Question 2: What does a seed need to wake up and germinate?
- Question 3: During germination, which way does the root grow, and which way does the stem grow?
- Question 4: Name three things a plant needs to grow strong and green.
- Question 5: How do flowers help the plant life cycle start again?

1. Seed, germination, growth, mature plant (with flowers).
2. Water and warmth.
3. The root grows down into the soil; the stem grows up toward the light.
4. Water, sunlight, air, and space (any three).
5. Flowers help make new seeds, and those seeds can be planted again to start the cycle over.
