What is this?
Chloroplasts are like tiny green food factories found inside plant cells. They use sunlight, water, and carbon dioxide from the air to make sugary food for the plant, a process called photosynthesis.
Key Parts to Explore
Outer Membrane
This is the protective skin that forms the outermost boundary of the chloroplast.
Inner Membrane
This second layer controls what materials enter and leave the chloroplast.
Stroma
This is the jelly-like fluid filling the chloroplast, where the plant builds its sugar food.
Thylakoid
These are small, flat, disc-shaped sacs inside the stroma where sunlight energy is first captured.
Did You Know?
Did you know chloroplasts have their very own DNA, just like they were tiny independent creatures that joined plant cells long ago?
