What the Heck Is That? Ordinary Things That Look Insane Microscopic!

Microscopic Brick Walls of Bananas

Slice into a banana and look at it through a lens, and it’s not just soft mush—it’s a surprisingly tidy grid of plant cells. The inside shows rows of rectangular cells packed with starch granules, each one looking like a tiny jellybean or grain of rice. These starches break down into sugars as the banana ripens, which explains why it tastes sweeter over time.

Zooming in, you can also spot cell walls holding everything together like brick and mortar. There’s structure hidden inside that squishy fruit, and it’s doing way more than just bruising easily. Turns out, bananas come with a built-in science lesson.
