Strawberry plants can reproduce through sexual reproduction with fruit and seed, as well as through asexual reproduction by sending out runners to create new plants, according to Garden Guides Runners, also called stolons, are sent out from the crown of a strawberry plant along the ground Nodes begin to appear on each stolon at set intervalsReproduction is an essential characteristic of all living organisms • eg mango and coconut Pome • juicy part is swollen receptacle • is usually a false fruit • example is a pear membrane inside the testa Hilum • a scar • spot where the seed was attached to the fruit or pod Micropyle • small hole through which water andPlant reproduction without seeds is present in mosses and ferns These plants combine sexual and asexual reproduction When the female and male gamete meet, structures are formed called spores These spores, once they are developed and mature, are then impulsed by wind until they fall on the floor and germinate, then new plants are born

Sporophyte Definition Plants may look simple, but the way they preserve their species is anything but 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 complicatedAll 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 490 viewsTrees reproduce sexually through seeds (female) and pollen (male) Gymnosperms produce a naked seed whereas angiosperms (flowering plants) produce a true seed

Biology Reproduction Notes
Agamospermy, asexual reproduction through seeds, occurs in flowering plants through many different mechanisms and a simple hierarchical classification of the different types is not possible Consequently, there are almost as many different usages of terminology for apomixis in angiosperms as there are authors on the subject Apomixis Citrus trees and many other species of angiosperms use their seeds as a method of asexual reproduction;Asexual reproduction does not involve the production and fusion of male and female gametes Asexual reproduction may occur through binary Fission, budding, fragmentation, spore formation, regeneration and vegetative propagationPlants have two main types of asexual reproduction in which new plants are produced that are genetically identical clones of the parent individual

A twocelled microgametophyte (called a pollen grain) germinates into a pollen tube and through division produces the haploid sperm An eightcelled megagametophyte (called the embryo sac) produces the egg Fertilization occurs with the fusion of a sperm with an egg to produce a zygote, which eventually develops into an embryoGymnosperms are any type of vascular plant that reproduce via an exposed seed While most flowering plants, known as angiosperms, have a seed enclosed in an ovary or fruit, gymnosperms (which means "naked seeds") do not have covers on their seeds Some examples of nonflowering plants that are classified as gymnosperms include Vegetative reproduction is a type of asexual reproduction found in plants This type of reproduction occurs when new individuals are formed without the production of seeds or spores The formation of new plants out of rhizomes or stolons is an example of vegetative reproductive, such as in the strawberry plant
