The typical "fern" plant the, sporophyte, is diploid.
gametophyte
The diploid number is "2n" and the haploid number is "n". Humans have 46 chromosomes, which are equal to the diploid number. half of these chromosomes are the haploid number, which is = 23.
A haploid cell only contains 23 chromosomes, whilst a diploid cell contains 23 x 2 chromosomes. When an egg cell (haploid) and a sperm cell (haploid) merge, a diploid cell is formed. Added: Called a zygote.
Four megaspores are formed from meiotic division of megapore mother cell which is diploid. We know that diploid cells undergo meiosis to give haploid cells. So, it seems to me that megaspores are haploid.

They are haploid. As meosis produces sex cells (sperm and eggs) they must have half the genetic material, so when fertilisation occurs the gamete formed has one full set of chromosomes, it is diploid.

Somatic (body) cells are diploid. Sex cells (gametes) are haploid.
Fingers are made of diploid cells. Haploid cells are the reproductive cells.
Meiosis produces 4 haploid cells.
ova is haploid
Haploid
There are two types of cells in the body - haploid cells and diploid cells. The difference between haploid and diploid cells is related to the number of chromosomes that the cell contains.
