Sexual reproduction in flowering plants: Pollination, fertilization

It involves an event development of anther and Microsporogenesis, development of male gametophyte, female reproductive whorl, structure of ovule Or megasporangium, development of ovule, development of pollen grains, development of endosperm.  Introduction Sexual reproduction Pre fertilization structures and events Male reproductive whorl – Androecium consists of a stamen. The number and length of stamen are […]

A seed is an embryonic plant that has a protective coat around it. Seed development is a stage in the reproduction of spermatophytes (seed plants), such as gymnosperms and angiosperms. After pollen fertilisation and some growth within the mother plant, the mature ovule produces seeds. The zygote produces the embryo, while the integuments of the

Latest: NEET 2024 Paper Analysis Recommended: NEET Rank Predictor 2024 See more: NEET Result 2024 Plants have a generational cycle in which the diploid sporophyte and the haploid gametophyte alternate. The haploid male and female gametes fuse to generate the diploid zygote. The zygote gives rise to the sporophyte generation. Males and females develop gametophytes in various ways.

Introduction In seed biology, double fertilisation results in endosperm and embryo development. Double fertilisation occurs when two male gametes of a pollen grain fuse with two distinct parts of the ovary. The endosperm plays a pivotal role in supporting embryonic growth. It supplies nutrients, protects the embryo, and controls embryonic growth by acting as a

The embryo develops from the zygote at the micropylar end of the embryo sac, which is located at the end of the embryo sac. Syngamy is the process by which a male gamete unites with an egg cell, and this is how it is generated. The embryo is present in the seed and is made

A ripened, mature ovary, as well as the contents of the ovary, is referred to as a fruit. The ovary is the reproductive component in the plant flower that contains the ovules. From the earliest stages of flower development until the ovules are fertilized and convert into seeds, the ovary functions to encapsulate and preserve the

The generative cell and the sperm spend their entire natural lives enclosed within the vegetative cell’s protective shell.  It is generated during the first division of the microspore and divides in the pollen grain or pollen tube to form two sperm cells, which are then released into the surrounding environment. As a result, the generative

Introduction It has been ten years since this journal published a review on apomixis, or asexual seed formation (Koltunow, 1993). The emphasis in that article was on the similarities known among apomictic processes in terms of sexual reproduction events. Apomixis inheritance had been established in some species, and molecular mapping studies had begun. However, the
