Is a mushroom diploid or haploid?
The thallus is haploid. It depends on the three basic life cycle of sexually reproducing fungi, in haplobiontic A life cycle, the thallus is haploid, in haplobiontic B life cycle the thallus is diploid and in diplobiontic life cycle, it has two thallus, a sporophytic thallus which is diploid and a gametophytic thallus which is haploid.
Does mitosis create haploid nuclei?
No. Haploid cells/nuclei can only be created in meiosis.
What is the dikaryotic stage of a fungus life cycle?
This dikaryotic stage in fungi reproduction involves the formation of two haploid nuclei, which later merge into a single nucleus

What is the process by which gametes are formed from diploid nuclei?
Meiosis creates four haploid cells, or gametes, from one diploid cell. Each gamete contains half of the chromosomes theorganismusually has. Gametogenesis creates mature gametes, being able to reproduce.

Is an ovule diploid or haploid?
The ovule largely consists of diploid cells except in its embrosac where egg apparatus, polar nuclei and antipodal cells are haploid.
Is the end product of mitosis haploid or diploid?
Mitosis produces DIPLOID cells- remember in mitosis your INCREASING the number of CELLS but the chromosome number is the SAME as the parentso a parent that has a (DIPLOID number of 10)will produce at the end of mitosis will produce 2 children with a diploid number of (10)That is why Mitosis is CONSERVATIVE.So in actuality, 1 diploid cell will produce 2 diploid cells in mitosisThe above is only true if the starting cell is itself diploid. However there are plenty of instances, especially in plants, in which cells that are haploid (the ones that give rise to pollen and egg, and endosperm nuclei, for example) or multiploid (hexaploid wheat, for example) undergo mitosis, and the cells that are produced have the same ploidy as the starting cell. Always. As noted above, mitosis is conservative. However, you ought not assume that you started with a diploid cell.
Does mitosis create haploid nuclei?
No. Haploid cells/nuclei can only be created in meiosis.
What is the process that results in 4 haploid gametes?
Meiosis results in four haploid cells known as gametes.

Is the primary endosperm nucleus haploid or diploid?
I am sure it is (3n).This is because In angiosperms most common type of embryo sac formation, there is fusion of 1 sperm nuclei + 2 polar nuclei=triple fusion resulting in a triploid primary endosperm nuclues.
What is a diploid parent cell undergoes mitosis then afterwards there will be?
Two diploid daughter cells with 46 chromosomes each. In Meiosis, there would be 4 haploid cells with 23 chromosomes each. Edited answer; A zygote undergoes mitosis to form an young embryo, which ultimately develops in to a new plant
Why are egg and sperm cells haploid?
are little more than flagellated nuclei. Each consists of a head, which has an acrosome at its tip and contains a haploid set of chromosomes in a compact, inactive, state.
What is the process by which gametes are formed from diploid nuclei?
Meiosis creates four haploid cells, or gametes, from one diploid cell. Each gamete contains half of the chromosomes theorganismusually has. Gametogenesis creates mature gametes, being able to reproduce.
Where does the process of double fertilization occur in plants?
The Generative nucleus arrives at the embryo sac inside the ovule and undergoes division to produce two haploid male nuclei. One of the male nuclei fuses with the haploid female gamete nucleus and for a diploid zygote. The other Male nuclei fuses with 2 polar female gametes to produce the triploid nucleus. This is known as the endosperm nucleus and it acts as a food source for developing zygote.
