Brick Fortress Wall 🧱
Cell Wall
A rigid outer skeleton outside the membrane. Gives trees and plants their upright, crisp structure.
🌿 Animal cells do NOT have a cell wall (that's why our skin is soft and flexible!).

Chloroplast
Contains green chlorophyll to capture sunlight and perform photosynthesis (making sugar food).
🍃 Plants make their own food; humans must eat meals!
