What is Haploid? – Meaning and Definition

Definition:

A haploid cell is a cell that contains only one complete set of chromosomes. In humans and many other organisms, haploid cells have half the number of chromosomes as body (somatic) cells.

Scientific Definition:

“A haploid cell is a cell that has a single set of unpaired chromosomes (n), typically found in gametes such as sperm and egg cells.”

In Simple Words:

A haploid cell is like half a recipe book—it has only one copy of each chromosome. When two haploid cells (like a sperm and an egg) combine during fertilization, they form a diploid cell with a full set of chromosomes.

Symbol for Haploid:

n (represents one set of chromosomes)

Examples of Haploid Cells:

Sperm Cell (Male Gamete)
Egg Cell (Ovum – Female Gamete)
Pollen Grains in Plants
Spores in Fungi and Algae

Haploid vs Diploid:

Feature	Haploid (n)	Diploid (2n)
Chromosome sets	1 set (single)	2 sets (paired)
Found in	Gametes, spores	Somatic (body) cells
Example (Humans)	23 chromosomes	46 chromosomes
Produced by	Meiosis	Mitosis

Importance of Haploid Cells:

Ensure genetic diversity through sexual reproduction.
Help in reducing chromosome number during reproduction so that offspring maintain the correct number of chromosomes.

Short Exam Note:

Haploid refers to a cell that has only one set of chromosomes (n). These are usually gametes (like sperm and egg cells), which combine during fertilization to form a diploid (2n) zygote.
