Grade 1 quiz: Plants and sunlight energy with answers

🌿 Quick Study Guide

☀️
• Photosynthesis: The process where plants convert sunlight, water, and carbon dioxide into glucose (sugar) for energy and oxygen.
💧
• Chlorophyll: The green pigment in plants that absorbs sunlight. It's essential for photosynthesis.
💡
• Sunlight: Provides the energy needed for photosynthesis. Different colors of light affect the rate of photosynthesis.
💨
• Carbon Dioxide ($CO_2$): A gas taken from the air through tiny pores in the leaves (stomata) and used in photosynthesis.
🌱
• Water ($H_2O$): Absorbed by the roots and transported to the leaves; also essential for photosynthesis.
🌡️
• Optimal Conditions: Photosynthesis works best within certain temperature ranges. Too hot or too cold can slow it down.
🧪
• Glucose ($C_6H_{12}O_6$): The sugar produced during photosynthesis, which plants use as food.
