Plant Growth and Needs
Investigate what plants need to grow and how their life cycle progresses from seed to mature plant.
What You Need to Know
Key Concept Diagram
Plants need sunlight, water, air (carbon dioxide), warmth, and soil nutrients to grow.
Photosynthesis is the process by which plants use sunlight to make food from water and carbon dioxide.
A plant's life cycle includes: seed, germination, seedling, mature plant, flowering, pollination, and seed dispersal.
Roots absorb water and nutrients; leaves capture sunlight; stems transport materials through the plant.
Key Vocabulary
germination

photosynthesis
The process plants use to convert sunlight, water, and carbon dioxide into food (sugar) and oxygen.
nutrients
Substances found in soil that plants absorb through their roots to help them grow.
life cycle
The series of stages an organism passes through during its lifetime.
