The word “cell” was used by Robert Hooke when he observed cork under his microscope. The compartments reminded him of small rooms or cells where monks lived, so he named them “cells.” This term has since become central to biology, representing the basic unit of life in all living organisms.

Inside a round-bottom flask, water takes on a convex shape, meaning it bulges outward. When light passes through this curved water surface, it bends or refracts, focusing the rays and enlarging the view of the object beneath. This natural refraction mimics how magnifying lenses work, allowing tiny dRead more
Inside a round-bottom flask, water takes on a convex shape, meaning it bulges outward. When light passes through this curved water surface, it bends or refracts, focusing the rays and enlarging the view of the object beneath. This natural refraction mimics how magnifying lenses work, allowing tiny details of an object to become more visible and clearer.
