Molecules called steroids, which include cholesterol, are membrane components that aid in membrane fluidity.
<h3>What is
steroids?</h3>
A steroid is an organic molecule with four rings arranged in a specific chemical structure that has physiological activity. The two primary biological functions of steroids are as signaling molecules and important cell membrane components that influence membrane fluidity. Animals, plants, and fungus all contain a variety of steroid species. All steroid molecules are made in cells using either lanosterol (opisthokonts) or cycloartenol (plants). Lanosterol and cycloartenol are created via the cyclization of the triterpene squalene.
The majority of the seventeen carbon atoms that make up the steroid core structure are arranged in three six-member cyclohexane rings (rings A, B, and C in the first picture) and one five-member cyclopentane ring (the D ring). The degree to which these functional groups are entangled with this four-ring core.

Answer:
A specialized cell means that even though they are similar, cells differ in size, shape or function depending on their role in our bodies. Each type of cell is modified to work in the way our bodies need it to. Specialized cell group together to form tissues.
