Layers, laminae
An onion bulb is made up of several layers. Cutting an onion in half, from the top to the root, will reveal the various layers.
it is 7 layers
An onion can be considered a vegetable with many layers. Each layer is thin and distinct, contributing to the overall flavor and composition of the vegetable.
The outermost layer of an onion is called the "skin" or "papery skin." This layer is typically dry and thin, serving as a protective covering for the layers beneath. It is usually brown or purplish in color, depending on the type of onion. The skin helps to keep the onion fresh and prevents moisture loss.

There are actually many layers inside the earth, much like an onion. The very center of the earth however, is called the core.
Onion skin weathering is a Geological process that happens mainly in deserts. As the rock heats up and expands by day, and cools and contracts by night, stress is often exerted on the outer layers. The stress causes the peeling off of the outer layers of rocks in thin sheets. Though this is caused mainly by temperature changes, thermal expansion is enhanced by the presence of moisture. Onion skin weathering has to do with rocks mostly in the desert. It is when the hot temperature of the day is then reduced to a cold temperature at night. This change in temperature causes layers of the rock to peel off like onion skin coming off. Therefore it is called onion skin weathering. Conclusion: Onion skin Weathering is when a rock heats up and expands (mostly deserts) And at night it cool and contract and layers of skin peels off
The many layers of an onion serve several purposes, primarily protection and nourishment. Each layer is made up of tightly packed cells that shield the inner layers from pests and environmental factors while also retaining moisture. Additionally, these layers store nutrients, allowing the onion to grow and thrive. This structural design helps the onion adapt to its environment and survive until it's ready to sprout.
There is only a single layer of cells in onion tissue. However, sometimes the tissue can fold over itself and appear to have two layers.
