Some examples of vegetative propagation are farmers creating repeated crops of apples, corn, mangoes or avocados through asexual plant reproduction rather than planting seeds Vegetative propagation can be accomplished from sideshoots, slips, stems and sections of tubers, bulbs or rhizomes Although many plants can be grown both asexually and from seeds,Example Vallisneria 4 Animals Brightly coloured and tasty fruits contain seeds with indigestible coats so that the seeds pass through the animal's digestive system undamaged Examples Tomato, plum, raspberry, grape Fertilization in Plants 1 The ovule with the fertilised cell develops into a seed The ovary turns into the fruit whileAbout Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How works Test new features Press Copyright Contact us Creators

A process called apomixis In one form, the egg is formed with 2n chromosomes and develops without ever being fertilizedSeed propagation is the method of plant propagation (multiplying, reproducing, or breeding new plants) that is done through the use of seeds Seeds are made up of three separate parts, and when a seed matures in an optimal environment, it will germinate and actively grow Irises can reproduce sexually through pollen and seeds but sometimes will use rhizomes to reproduce as well This is why you may see a patch of irises growing close together they are all sharing

Asexual reproduction is through stems, roots and leaves Plant reproduction comes in two types sexual and asexual Sexual reproduction is similar to human reproduction, in which male pollen and female ovarian germ cells fuse into a new organism that inherits the genes of both parents The sexually reproductive part of a plant is the flower Asexual reproduction involvesMany seedless varieties are obtained through the vegetative method Less attention is required by the plants grown through asexual means than through seeds Sexual Reproduction In Plants The reproductive parts of plants are flowers, Stamen being male reproductive part and pistil being the female reproductive part If one of these reproductive parts are present in a flower, it is said to be a unisexual flower Example Urena and Xanthium are examples of this These seeds get dispersed because of sudden jerks in animal movement Castor and Balsam are examples of this This situation is seed dispersal And in case of fruit formation, once it ripens, the other parts of the flower fall off Some examples of sexual reproductive plants are mango, apple, almond, and walnut

Seeds therefore allow plants to disperse the next generation through both space and time With such evolutionary advantages, seed plants have become the most successful and familiar group of plants Both adaptations expanded the colonization of land begun by the bryophytes and their ancestors Fossils place the earliest distinct seed plants at about 350 million years ago The firstAll plants can reproduce through seeds, except for those hybrids/cultivars that are so radically modified that they have lost reproductive function Seedless watermelon and hybrid tea roses would be examples of those that CANNOT reproduce form seed Examples of bacteria that are capable of forming endospores include Clostridium and Bacillus Algal Spores Chlamydomanas reinhardtii is a a type of green algae that reproduces asexually by producing zoospores and aplanospores These algae are also capable of sexual reproduction Dartmouth Electron Microscope Facility, Dartmouth College (Public Domain

It is the fastest method of reproduction, eg, potato crop requires more than one year with the help of seeds, however, it takes only 3 to 4 months with the help of tubers Similarly, lily takes 4 to 7 years through seeds, however, 1 to 2 years by bulbs Plants that reproduce sexually have sex parts which we know as flowers The process of reproduction involves the fusion of male gametes, namely, pollen with the female gamete, also known as ovules This fusion results in the formation of a zygote and an endosperm nucleus, which grow into seeds and fruits respectivelyPlants have two ways of reproduction, sexual by means of seeds, and asexually or vegetatively by means of vegetative tissue Both ways occur in living plants in nature In nature, some plants reproduce mainly vegetatively while others rely almost totally on sexual reproduction For the plant breeder it is desirable to be able to manipulate sexual and vegetative reproduction

They have a life cycle which involves alternation between a generation of one set of chromosomes and two sets of chromosomes in order to reproduceWhile the term sporophyte is referred to as plants that produce spores, the real definition is more complicated and interesting eg A stolon, or runner, is a stem that runs along the ground In both the above types, axillary buds frequentlyPlant reproduction without seeds Not every plant grows from a seed Some plants, like ferns and mosses, grow from spores Other plants use asexual vegetative reproduction and grow new plants from rhizomes or tubers We can also use techniques
