What cells are haploid?
Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
Examples of Haploid Cells
Sperm and egg cells (the reproductive cells of humans) Spores (the reproductive cells of fungi, algae, and plants) Pollen (the reproductive cells of male plants)
Meiosis is the process by which replicated chromosomes undergo two nuclear divisions to produce four haploid cells, also called meiocytes (sperms and eggs).
Haploid cells: Gametes, egg and sperm (contain a single set of chromosomes).
At the end of meiosis II, four haploid cells are formed.
The zygote is diploid because two haploid sex cells are significantly combined to create a diploid zygote. The zygote undergoes various changes and finally results in the formation of a new life or a baby. Hence, according to the question, the option that is not haploid is the zygote.
The zygote is endowed with genes from two parents, and thus it is diploid (carrying two sets of chromosomes). The joining of haploid gametes to produce a diploid zygote is a common feature in the sexual reproduction of all organisms except bacteria.
And what type of cells are diploid? The chromosomal diploid number in humans is 46 (i.e. 2n=46 chromosomes or 23 pairs of chromosomes). All the body cells like, blood cells, skin cells, muscle cells are diploid. Only sex cells or gametes are not diploid; sex cells are haploid.
Thus, the correct answer is 'Microsporangia. '
Skin, liver, and hair cells are all types of body cells. Therefore, answers a, b, d, and f are all diploid cells. Haploid cells are also referred to as sex cells. These cells contain one set of chromosomes.
Does mitosis produce 4 haploid cells?
Mitosis produces two genetically identical diploid cells, whereas meiosis produces four non-identical haploid cells.
In reproductive sex gametes, the sperm and the eggs, the number of chromosomes is reduced. In humans it is reduced from 46 down to 23. This is the haploid number of chromosomes and consists of one each of the homologues. It is often represented by the letter "n".
Human gametes (egg and sperm cells) are haploid, containing 22 autosomes and one sex chromosome.
A human brain cell has 23 pairs of chromosomes, for a total of 46 chromosomes. Brain cells are called diploid cells because they have chromosomes that are in pairs.
Three haploid antipodal cells (1) occur at the upper end of the emryo sac. A large endosperm mother cell containing two haploid polar nuclei (2) occupies the central portion of the embryo sac. At the lower end (nearest the micropyle and funiculus) are two haploid synergid cells (3) and one haploid egg.
In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.
They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.
Diploid vs. Haploid Cells - YouTube
In microbiology, a haploid cell is the result of a diploid cell replicating and dividing twice through meiosis. Haploid means "half." Each daughter cell produced from this division is haploid, meaning that it contains half the number of chromosomes as its parent cell.
Are gametes the only haploid cells?
There are three main categories of sexual life cycles. In a diploid-dominant life cycle, the multicellular diploid stage is the most obvious life stage, and the only haploid cells are the gametes.
The process of meiosis, which produces sex cells, splits the 4n parent cell into four haploid (n) daughter cells, which can then be combined in sexual reproduction to form a diploid offspring.
A sporophyte (/ˈspɔːr. əˌfaɪt/) is the diploid multicellular stage in the life cycle of a plant or alga. It develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent.
In terms of chromosomes, the gametophyte is haploid (has a single set of chromosomes), and the sporophyte is diploid (has a double set). In bryophytes, such as mosses and liverworts, the gametophyte is the dominant life phase, whereas in angiosperms and gymnosperms the sporophyte is dominant.
Diploid cells contain two sets of chromosomes, one set obtained from each biological parent. On the other hand, sex cells (gametes – eggs and sperm cells) are haploid cells containing only a set of chromosomes. Examples of diploid cells in humans are nerve cells, muscle cells, bone cells, skin cells, etc.
6. An example of a haploid cell is: A red blood cell. A cell found in any part of your body except sex cells (and red blood cells)
Diploid describes a cell that contain two copies of each chromosome. Nearly all the cells in the human body carry two homologous, or similar, copies of each chromosome. The only exception is cells in the germ line, which go on to produce gametes, or egg and sperm cells.
Both haploid and diploid cells can undergo mitosis. When a haploid cell undergoes mitosis, it produces two genetically identical haploid daughter cells; when a diploid cell undergoes mitosis, it produces two genetically identical diploid daughter cells.

How is Meiosis I Different from Meiosis II?
| Meiosis I | Meiosis II |
|---|---|
| Starts as diploid; ends as haploid | Starts as haploid; ends as haploid |
Each gamete contains only one chromosome from each homologous pair. This makes the cell haploid, meaning that it has half the chromosome number of the original diploid cell.
Is a nerve cell haploid?
That means, the cells that participate in the process of reproduction contain only one set of chromosomes and hence are haploid. These are the cells that undergo meiosis. Examples of diploid cells are: Somatic cells like Skin cells, muscle cells, blood cells , heart cells, nerve cells.
Definition. Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). In humans, body (or somatic) cells are diploid, containing two sets of chromosomes (one from each parent).
Human eggs are haploid cells. They are produced by meiotic division and contain 23 chromosomes (n=23). All cells in the human body other than gametes are diploid cells.
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).
For the most part, in mitosis, diploid cells are partitioned into two new diploid cells, while in meiosis, diploid cells are partitioned into four new haploid cells.

| Organism | Diploid Chromosome Number (2n) |
| Lily | 24 |
| Frog | 26 |
| Humans | 46 |
The diploid (2n) number of chromosomes is the number of chromosomes in a somatic, body cell. This number is double the haploid(n) or monoploid (n) number. The haploid (n) number of chromosomes is the number of chromosomes found in a gamete of reproductive cell. This number is half of the diploid (2n) number.
At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.
Sperm refers to male gametes, whilst ova or egg cells refers to female gametes. Gametes are haploid cells, meaning they have only one copy of each chromosome. These reproductive cells are created through meiosis, a type of cell division.
What's a diploid number?
The diploid number is the number of chromosomes required for two complete copies of the organism's genome (the entirety of its genetic information). In animals, this is the number of chromosomes in most cells (gametes being an important exception).
Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our 'haploid' number 23. Of the 23 pairs, 22 are known as autosomes. The 23rd pair is made up of the sex chromosomes, called the 'X' and 'Y' chromosome.
Diploid cells have two homologous copies of each chromosome, usually one from the mother and one from the father. All or nearly all mammals are diploid organisms.

During fertilisation, an egg and sperm (gametes) combine to form a cell that contains a complete complement of DNA. In humans, these gametes are haploid as they have one copy of each chromosome, contributed from each parent.
Each gamete contains only one chromosome from each homologous pair. This makes the cell haploid, meaning that it has half the chromosome number of the original diploid cell.
Skin, liver, and hair cells are all types of body cells. Therefore, answers a, b, d, and f are all diploid cells. Haploid cells are also referred to as sex cells. These cells contain one set of chromosomes.
Humans are diploid, and most of the body's cells contain 23 chromosomes pairs. Human gametes (egg and sperm cells), however, contain a single set of chromosomes and are said to be haploid.
