What else can I help you with?
Are pollen grains haploid or diploid if they have two nuclei the generative and the tube nuclei?
Pollen grains with generative and tube nuclei have two haploid nuclei.
Does mitosis create haploid nuclei?
No. Haploid cells/nuclei can only be created in meiosis.
What event occurs during telophase 2?
Formation of 4 haploid nuclei
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.
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.
Are pollen grains haploid or diploid if they have two nuclei the generative and the tube nuclei?
Pollen grains with generative and tube nuclei have two haploid nuclei.
Does mitosis create haploid nuclei?
No. Haploid cells/nuclei can only be created in meiosis.
What structure contains two haploid nuclei?
Ascus is the structure that contains two haploid nuclei in fungi, particularly in the Ascomycota division. These nuclei are produced by the fusion of two haploid nuclei during sexual reproduction and can undergo meiosis to produce spores.
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.
Which event occurs in telophase II?
formation of four haploid nuclei.
What event occurs during telophase 2?
Formation of 4 haploid nuclei
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 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 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.
Which event occurs in telophase 2?
Formation of four haploid nuclei. ignore nova net = scam
How many pairs of the nucleus occur in meiosis?
in meiosis, two new haploid sex cells are "born" by the division of two other haploid sex cells. So, at the end, there are 4 nuclei.
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.
