Grade 7 plant cell organelles quiz with answers.

📚 Quick Study Guide

• 🌿 Cell Wall: Provides support and protection to the plant cell. Made of cellulose.
• ☀️ Chloroplasts: Where photosynthesis happens. Contains chlorophyll. Equation: $6CO_2 + 6H_2O + Light \rightarrow C_6H_{12}O_6 + 6O_2$
• 🧠 Nucleus: The control center of the cell. Contains DNA.
• 💧 Vacuole: Stores water, nutrients, and waste. Large central vacuole in plant cells.
• ⚡ Mitochondria: The powerhouse of the cell. Site of cellular respiration.
• 📦 Endoplasmic Reticulum (ER): Transports materials within the cell. Can be rough (with ribosomes) or smooth (without ribosomes).
• 🔬 Ribosomes: Site of protein synthesis. Found on rough ER and in the cytoplasm.
• 🎯 Golgi Apparatus: Processes and packages proteins and lipids.
• 💡 Cytoplasm: Jelly-like substance inside the cell where organelles are located.
