How do plants actually make their own food?
You eat to get energy, but plants can't order takeout or snack on chips. Instead, your typical plant grabs energy straight from sunlight and turns it into food , a process called photosynthesis. When sunlight hits the green parts of a plant, your plant uses that energy to turn carbon dioxide from the air and water from the soil into glucose, a sugar it can use for energy or growth. Oxygen is released as a byproduct, which you end up breathing.
Inside each leaf, there are tiny green structures called chloroplasts. These are packed with chlorophyll, the pigment that makes leaves look green. Chlorophyll is like a solar panel, catching sunlight and starting the whole food-making process. Most of these chloroplasts are crammed into the upper layer of the leaf, called the palisade mesophyll, where they can soak up the most light.
When a plant uses sunlight to build glucose from water and carbon dioxide, that's called <b>photosynthesis</b>. It's how plants make their own food.
Imagine your phone charging from sunlight, but instead of just storing power, it actually builds itself a snack using that energy. That's basically what a plant does with photosynthesis.
Here's a twist: plants look green because chlorophyll doesn't absorb green light , it reflects it, so that's what you see.
