Cell structure and function quiz Grade 7

📚 Quick Study Guide

• 🔬 Cells: The basic building blocks of all living things. Think of them like tiny LEGO bricks that make up everything!
• 🧱 Cell Structure: Cells have different parts called organelles, each with a specific job.
• 🧠 Nucleus: The "brain" of the cell, containing DNA. It controls everything the cell does.
• 🛡️ Cell Membrane: The outer layer of the cell that controls what enters and exits. It's like a gatekeeper!
• ⚡ Cytoplasm: The gel-like substance inside the cell where all the organelles are located.
• 💪 Cell Wall (Plant Cells): A rigid outer layer that provides support and protection to plant cells. Animal cells don't have this.
• ☀️ Chloroplasts (Plant Cells): Where photosynthesis occurs, allowing plants to make their own food using sunlight.
• 📦 Vacuoles: Storage bubbles that can hold water, nutrients, or waste.
• 🌱 Cell Function: Cells carry out life processes like growth, reproduction, and energy production.
