Cholesterol makes up cell membranes and is used to create hormones.
Cell membranes are the outer covering of the cell that protect it from the outer environment. A cell membrane is a bilayer of lipid, composed of protein and cholesterol as well. The cholesterol is essential to maintain the proper integrity of the cell membrane.
Hormones are the chemical messengers that are released at one site and they perform their function at another location of the body. Hormones can be made up of several macromolecules like polypeptides, amine acids or cholesterol. The example of hormones made up of cholesterol are: glucocorticoids, mineralocorticoids, and sex hormones.

Explanation:
ALTERNATION OF GENERATIONS is a unique phenomenon whereby certain organisms switch between a diploid state and a haploid state in their reproductive life cycle. It is a feature of plants (higher and lower).
A plant is a diploid organism (2n) i.e. contains two set of chromosomes. This diploid state of the plant is called the SPOROPHYTE. The diploid sporophyte (2n) of a plant undergoes meiotic division (reduction division) to produce haploid spores. These haploid spores germinates and grows via mitosis (duplication division) to form the haploid GAMETOPHYTE.
The haploid gametophyte (n), via structures called GAMENTAGIA, produces haploid gametes. The male gametophyte produces male gametes (sperm) while the female gametophyte produces female gamete (egg). These haploid gametes eventually fuse in a process called FERTILIZATION to produce a diploid ZYGOTE (2n) i.e. sperm (n) + egg (n) = zygote (2n). The ZYGOTE undergoes series of mitotic divisions (growth) to form the diploid SPOROPHYTE (2n) of the plant. The cycle restarts again in that order, hence it is called ALTERNATION OF GENERATIONS.
N.B: Mitosis maintains the number of chromosomes of the parent cell while meiosis reduces the chromosomal number of the parent cell by half.
