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.
Is pollar nuclei a haploid or a diploid?
Polar nuclei are typically haploid. In the context of plant reproduction, specifically within the embryo sac of angiosperms, polar nuclei are formed from the fusion of two haploid nuclei. These nuclei eventually contribute to the formation of the triploid endosperm when fertilization occurs.
During fertilization the nuclei of two haploid gametes join to form a diploid?
During fertilization, the nuclei of two haploid gametes—one from each parent—fuse to form a diploid zygote. This process restores the diploid chromosome number, which is crucial for the development of a new organism. The resulting zygote contains a unique combination of genetic material from both parents, contributing to genetic diversity. This diploid zygote will then undergo cell division and differentiation to develop into an embryo.
What is the ploidy of ascocarp?
The ploidy of ascocarps is typically diploid, meaning they have two sets of chromosomes. This is because ascocarps are reproductive structures formed during sexual reproduction in fungi, where haploid nuclei from two different mating types fuse to form a diploid zygote.
Is a mushroom diploid or 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.
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 pollar nuclei a haploid or a diploid?
Polar nuclei are typically haploid. In the context of plant reproduction, specifically within the embryo sac of angiosperms, polar nuclei are formed from the fusion of two haploid nuclei. These nuclei eventually contribute to the formation of the triploid endosperm when fertilization occurs.
Describe the processes of plasmogamy and karyogamy in fungi?
Plasmogamy is the fusion of cytoplasm from two haploid fungal cells, resulting in the formation of a dikaryotic cell with two separate haploid nuclei. Karyogamy is the fusion of the two haploid nuclei within the dikaryotic cell, leading to the formation of a diploid nucleus, which eventually undergoes meiosis to produce haploid spores.
During fertilization the nuclei of two haploid gametes join to form a diploid?

What is the fusion of nuclei in fungi?
A form of sexual reproduction. The gametes of fumgi are not termed male and female but rather, + and -. They bring + and - nuclei into the same cell. Sfter a period of development, these nuclei form a diploid zygote.
What is the dikaryotic stage of a fungus life cycle?
The dikaryotic stage in a fungus life cycle is characterized by cells containing two genetically distinct nuclei that are not yet fused. This stage follows the fusion of haploid nuclei from two mating strains but precedes the formation of diploid nuclei through nuclear fusion. Dikaryotic cells are essential for the development of fruiting bodies and sexual reproduction in fungi.
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.
What is haploid nuclei?

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.
