Start studying Sexual reproduction in plants and the menstrual cycle Learn vocabulary, terms, and more with flashcards, games, and other study toolsThe evolution of seeds allowed plants to decrease their dependency upon water for reproduction Seeds contain an embryo that can remain dormant until conditions are favorable when it grows into a diploid sporophyte Seeds are transported by the wind, water, or by animals to encourage reproduction and reduce competition with the parent plantNov 16, 16 · The flower is a pretty complicated plant, with lots of little parts which help it reproduce (or make more of itself) For that reason it's probably best to look at the basics of flower reproduction before we get into the more difficult stuff like the parts of the flower, its life cycle, and how to grow your own flowers

Because vegetative reproduction is a form of asexual reproduction in plants, it can result in offspring that are genetically distinct from parent plants (via genetic recombination);Especially when we look at their life cycle, from first growth to reproduction It all starts with a seed that cracks open and starts to grow when it has the right amount ofNonRecurrent Apomixis (Haploid Seed/Plant Formation) Here the seed/plant develops from the unfertilised egg cell or any other unfertilised haploid cell of embryo sac In this type of apomixis the first event of normal sexual cycle, meiosis takes place, the embryo sac is formed normally, but due to various reasons the fertilisation does not

Reproduction in plants takes place sexually and asexually as well But the majority of the flowering plants reproduce sexually The flower is the reproductive part of a plant ie, both male and female gametes are produced by flowersThe reproductive cycle of a flowering plant is the regular, usually seasonal, cycling back and forth from sporophyte to gametophyte The flower produces two kinds of gametophytes, male and female The female gametophyte arises from a cell within the ovule, a small structure within the ovary of the flowerAfter meiosis it is haploid (haplophase) The two

THE CONIFER LIFE CYCLE AN EXAMPLE OF SEED PLANT REPRODUCTION As with ferns, the dominant plant is the sporophyte, which in this case, is the conifer tree •Since all these trees ultimately produce seeds, it may seem contradictory that they represent the sporebearing generation or sporophyte •Actually, conifers produce two kinds of sporesMar 05, 18 · Evolution of Gymnosperms The fossil plant Elkinsia polymorpha, a "seed fern" from the Devonian period—about 400 million years ago—is considered the earliest seed plant known to dateSeed ferns produced their seeds along their branches, in structures called cupules that enclosed and protected the ovule—the female gametophyte and associated tissues—which develops into a seedA plant's life cycle involves two alternating multicellular stages – a Diploid (2n) sporophyte stage and a Haploid (1n) gametophyte stage
