Post fertilization changes will be:
- Post fertilization involves a series of events that takes place after fertilization.
- Formation of diploid zygote and then it develops into an embryo.
- Endosperm cells serve as a source of nutrition.
- The ovule becomes the seed.
- The ovary becomes the fruit
- The outer and inner integuments of the ovule become the seed coat of the seed.
- Petals and sepals fall off.

In angiosperms, double fertilization takes place; one male gamete fuses with the egg cell to form the zygote and another male gamete fuses with the polar nuclei to form the endosperm.
Post Fertilization: Events and Changes in Plant - Collegedunia
The process of development of endosperm and embryo followed by the formation of fruit after fertilisation is called post fertilization. A series of events takes place to form seeds, including four different processes such as development of endosperm and embryo followed by the maturation of ovules into seeds and a fruit is developed from the ovary of female gametes.

Definition of Post Fertilization
Post fertilization is defined as a series of events that occurs to form a fruit from the plants. In this process, after the fertilization of plants, an embryo division takes place mitotically to produce a multicellular embryo. The endosperm in zygote breaks to form a mass of endosperm cells and give nutrition to the developing embryo.
Events of Post Fertilization
There are series of events that happen in the development of plants after their fertilization process to form a fruit from a diploid zygote. Below we have described about the four different developmental steps that occurs during post fertilization:
Things to Remember
The endosperm is a triploid primary nucleus which forms a nutritive tissue.
What are the changes that occur after fertilization?
In the reproductive system of a plant, after fertilization, several changes happen that causes the development of a fruit. Here are the four developmental steps to describe the post fertilization changes in a flower -. Endosperm. Embryogeny.
What is the process of fertilization?
Fertilization is the fundamental step to initiate the reproductive system in plants. In this process, the female and the male gamete merge to produce a diploid zygote. A series of post fertilization events take place in the zygote, and a seed develops. Angiosperm is the most developed species of plant that consists of flower, stems, leaves, ...
When does a zygote start dividing?
Mostly, after some endosperm formation, the zygote starts dividing. At first, the zygote develops to a pre-embryo and then it matures to a complete embryo. The stages of embryogeny are similar for dicot and monocot plants. However, they have different structures.
What is the development of endosperm?
The development of endosperm can be categorised into three types -. Nuclear formation .
How do fruits develop?
Development of Fruit. A fruit develops through differentiation and cell divisional process in the ovary. The ovary wall matures into pericarp (which is the fruit wall). In some fruits like guava, cucumber, etc. the pericarp is fleshy. However, in pea, mustard, etc. a leathery pericarp is found.
How does polysiphonia reproduce?
Ø Polysiphonia reproduces by means of vegetative, asexual and sexual methods.
Why is the thallus of Polysiphonia red?
Ø The thallus color of Polysiphonia is varied from red to purple. Ø The red coloration is due to the abundance of the pigment r-phycoerythrin.
How many phases are there in the life cycle of polysiphonia?
Ø The life cycle of Polysiphonia is completed in three phases.
What Is Post Fertilization?
Post-fertilization is a series of events that takes place after fertilization to develop a seed from an ovule and a fruit from an ovary.
What is the process of growth and development of an embryo from a zygote in the flowering plants?
Embryogeny. Embryogeny is defined as the process of growth and development of an embryo from a zygote in the flowering plants. Embryo development stages are the same in both monocot and dicot plants. In dicot plant embryo, an embryonal axis and two cotyledons are present. Two parts are present in the embryonal axis.
What is the tissue that is present in the seeds of flowering plants during the time of fertilization?
Endosperm. The endosperm is a type of tissue, which is present in the seeds of flowering plants during the time of fertilization. Reserve food materials fill in the cells of endosperm tissue. It provides nutrition to the developing embryo in the form of starch.
