I learned something new tonight. While exploring nature, I often find leaves with bumps on them. But I haven't researched it before, and tonight I found the answer here. Thank you Mom, for sharing.

Some bumps on leafs are called galls and are caused by insects.
They happen when a tiny organism (like a mite, insect, or fungus) feeds on or lays eggs in a developing leaf. The plant reacts to the chemical irritation by rapidly growing abnormal tissue around the invader—essentially building a little protective room for it.
Leaf Galls are typically the same color as the leaf or turn bright red, yellow, or brown: Mites, aphids, or tiny wasps can cause them
The good news is they rarely harm the overall health of an established plant or tree.
Yes, the color is the same as the leaves, and I often find these bumps on aging leaves. Thank you, Mom, for the explanation. It means a lot to me, as someone who loves exploring the outdoors.
