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.

∙ 9y agoIt is called double fertilization because flowers can fertilize themselves and also get fertilized by other plants.

∙ 7y agoDouble fertilization is a complex fertilization process of flowering plants. During double fertilization the female gametophyte fuses with two male gametes.

What is the relationship between pollination and Fertilization?
No. The process of the joining of male and female reproductive cells is fertilization. The word is often misapplied to pollination which is a preliminary to fertilization in plants. The two are often confused.
When does fertilization in mitosis occur?
Fertilization does not occur in mitosis. Fertilization signals for the start of mitotic division in embryos.
What is fertilisation in plants?
In plants, fertilization is a process of sexual reproduction, which occurs after pollination and germination.Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote. It is a physicochemical process which occurs after the pollination of the carpel. The complete series of this process takes place in the zygote to develop into a seed.In the fertilization process, flowers play a significant role as they are the reproductive structures of angiosperms (flowering plants). The method of fertilization in plants occurs when gametes in haploid conditions fuse to produce a diploid zygote.In the course of fertilization, male gametes get transferred into the female reproductive organs through pollinators (honey bees, birds, bats, butterflies, flower beetles) and the final product will be the formation of the embryo in a seed.Fertilization ProcessIn flowers, the pollen grain germinates after the pollination of the carpel and grows into the style by creating the pathway for the pollen grain to move down to the ovary.The pollen tube opens into the ovule through the micropyle and bursts into the embryo sac. Here, the male nucleus unites with the nucleus of an egg inside the ovule forming a diploid zygote, which later swells up and develops into a fruit.Types of FertilizationFertilization process can be grouped into three types and are classified mainly based on the entry of the pollen tube into the ovule.PorogamyIt is the common type of fertilization carried out in all angiosperms or flowering plants. In this type of fertilization, the pollen tube enters the ovule through the micropyle.ChalazogamyThis type of fertilization is carried out on all Casuarina species of plants. In this condition, the pollen tube enters the ovule through the pollen tube.MesogamyThis type of fertilization is seen in all Cucurbit plants, such as pumpkin, ridge gourds, bitter gourd and other gourd plants. In this type of fertilization, the pollen tube enters the ovule through its middle part or through the integuments of the ovule.Double FertilizationDouble fertilization is a process of fertilization characterized by the fusion of a female gametophyte with two male gametes. In this mechanism, one sperm cell fuses with the egg-producing zygote, and the other fuses with the two polar nuclei to make the endosperm. All angiosperm plants undergo double fertilization process.Seed plants can go through the process of fertilization, when seedless plants cannot. If the seedless plants do go through fertilization they would require a flower for fertilization to occur.
How does water aid the fertilization of some organisms?
Depending on the species, fertilization can occur internally or externally. Water aids the fertilization of some organisms because organisms that reproduce externally need water for fertilization to occur.
Does double fertilization occur in the Division Anthophyta?
Mi verga es la mas grande del mundo ! quien la mamaria ?
Do all plants need water to make fertilization occur?
All plants need water.

How do independent assortment crossing over and random fertilization affect the rate of evolution?
They will determine how the fertilization will occur. These can allow for some interesting changes to occur with the different plants.
How does fertilization in a seed plants differ from fertilization in seedless plants?
Seed plants produce seeds to overcome the adverse environmental conditions whereas seedless plants overcome the adverse environmental conditions by vegetative parts such as tubers, gemma cups or even spores. Since formation of seed involves genetic advance seed formation for reproduction is more successful in nature.
Which process must occur before any division can take place?

Which process must occur before any cell division can take place?
Fertilization
Where in the plant does fertilization occur?
In most cases, the roots of the flower plants are treated with fertilizers.

In the leaves of flowering plants were does the process of photosynthesis occur?
chilorplasts
Describe where pollination and fertilization occur?
Fertilization occurs in the ovule
Why are bryophytes considered incompletely adapted to the terrestrial environment when compared with other plants?
They require moisture for fertilization to occur. Their sperm are flagellated.
