Haploid and diploid are terms which refer to the number of copies of a chromosome that are found in the genome of an organism.
In humans, for example, there are two copies of each (of our 23) chromosomes. Thus, we are diploid. If there is only one copy of a chromosome, this is called haploid. Human sex cells as well as most plant sex cells (sperm/ pollen, ovum/ oval) are haploid.
This is how you end up with a complement of chromosomes that is half your father's, half your mother's. Two haploid cells come together to form a diploid cell, and this cell eventually becomes a person.
Diploid is a full set of chromosomes inherited from both parents. In humans this would be 46 chromosomes, or 23 pairs in, mostly, somatic cells.
Haploid is half this number of chromosomes and is the result of meiosis, where as diploid is the result of normal cellular mitosis (as well as the result of fertilization).
In genetic notation haploid is depicted with "n" and diploid "2n"

∙ 13y agoDiploid is 2n while haploid is n. The actual number (represented by n) varies by species. In humans, n = 23. A haploid gamete (sex cell, e.g. egg or sperm) is n (23 chromosomes). An autosome (body cell) is 2n, diploid, which is 2x23, equaling 46 chromosomes in the human body cells.

What is meant by a haploid Cell?
A sex cell that has only half ("ha" = half) one set of chromosomes. Once this cell were to join with the other haploid cell (either an egg or sperm, dependant on what the original haploid cell was) and fertilisation was to occur it would then become a diploid cell ("d" = double)
Does crossing over produces chromosomes that carry genetic information from both homologous chromosomes?
The question is not proper. Please define more. I assume you meant whether the genetic information is transferred between homologous chromosomes. Yeah it does. When the two homologous chromosomes pair up to form bivalents, crossing over occurs between them.
When the cell is preparing to divide the material that thickens and becomes the chromosomes is what material?
Its not exactly that there's a material that thickens and becomes chromosomes as much as that the Chromatin (DNA) gets wrapped around certain proteins (Histones), which condenses it, and makes it visible in the form of Chromosomes (long strands of DNA that have been wrapped tight enough around proteins that they are visible),So the answer you're looking for is either chromatin or DNA (i think that's what you meant by your question)
Can a fertilized egg survive if it has ninety two chromosomes?
From the category the question was placed in I assume you meant a human egg cell. In which case, the short answer is no. The longer version would be that a tetraploid zygote might survive for a while but it will not make it through the embryonic stage. The fetus will not form, the embryo will not survive that long.
What beneficial biological processes involve mitosis?
The processes which use Mitosis are life in general. It is the separation on chromosomes during the develop meant of life according to the DNA which it follows.
What is meant by diploid chromosomes number?
Diploid mean double.Two set of chromosomes (23) from father and (23) from mother.
What is meant by a haploid Cell?
A sex cell that has only half ("ha" = half) one set of chromosomes. Once this cell were to join with the other haploid cell (either an egg or sperm, dependant on what the original haploid cell was) and fertilisation was to occur it would then become a diploid cell ("d" = double)
What is meant by haploid number of cells?
Haploid= Half.
Example of a human diploid cell?
Homp sapien cell are diploid. all except the sex cells i.e sperm in males and eggs in females. Trypanosomes - parasitic protozoa that cause African sleeping sickeness are also diploid organisms.
What is meant by a triploid organism?
The diploid cell is one wherein each chromosome has its homologous counterpart for pairing during meiosis. Diploid cells are formed by gametic union and after completion of meiosis in a diploid cell haploid cells are formed. These haploid cells get converted into gametes to unite again to form the diploid cell.
What is the number of a hapliod?
There is no such word as a "hapliod". If you meant haploid, the answer depends on the species.There is no such word as a "hapliod".

In plants what is meant by saying that the cells of a sporophyte phase are dipliodor 2n?
it just means that the gamete has a complete set of chromosomes. haploid means that the gamete does not have a complete set of chromosomes and needs another haploid cell (typically this is sperm and egg) to fuze with it and create a zygote with a complete set of chromosomes.
How many chromosomes would be in a zygote if the bird has 30 chromosomes?
A zygote is a fertilized egg cell, so it is diploid and thus has a full set of DNA. If the adult has 30 pairs of chromosomes, the zygote would have 30 pairs. If there are 30 chromosomes, then the zygote will have 60 (30 from the mother and 30 from the father). It comes down to whether you meant individual chromosomes or pairs of chromosomes.
What is a geonome?
I think you meant "genome." The definition of genome is: The total genetic content contained in a haploid set of chromosomes in eukaryotes, in a single chromosome in bacteria, or in the DNA or RNA of viruses. Source: American Heritage Dictionary (link below)
What is meant by synapsis?
A synapsis is the pairing of 2 homologous chromosomes.
What is meant by the word Chromosome?
chromo= coloured somas=bodies colour bodies = chromosomes
Are chromosomes and genes the same or not in the original cell?
Your question is not clear. If you meant to ask, "Do chromosomes and genes remain the same in the original cell? (i.e. after cell division)" then yes.
