Plants use more than one method of reproduction. The first life forms on Earth were photosynthetic. They used light from the sun to make sugar, and then consumed the sugar to reproduce. The leap from single cell organisms to multi cell organisms is unknown, and there are many theories.&nbsp;<\/p>\n<p>I think the plants you refer to have roots and leaves and reproductive organs that produce seeds. Evolution states that these plants evolved from simpler plants, but nobody knows the exact evolutionary path from single cells, to plants without seeds, to plants with seeds.

is a pretty broad term covering a wide range of organisms, not all of which reproduce sexually.The simplest plants are single-celled green algae.\u00a0 They don\u2019t have separate seeds; they\u2019re just a single cell.\u00a0 Some algae have just a single set of chromosomes; others chromosome pairs.\u00a0 You get double chromosomes when two algae merge, giving you a unique organism that can the reproduce.\u00a0 Sometimes it will reproduce by simple fission, giving you two new organisms with unique single-chromosome genomes.<\/p>\n<p>The history of plants goes from single-celled algae to simple clusters of algae (with different genomes) to multicellular algae with a single genome but different cells performing different tasks called Charophytes.\u00a0 They spawn special cells with half genomes (like our own sperm and egg cells) that go out and find other gametes from other charophytes, but they don\u2019t distinguish separate male and female genders.\u00a0<\/p>\n<p>You can think of these as alternating between half-genome generations (&#8220;haploid&#8221;) and full-genone generations (&#8220;diploid&#8221;).\u00a0 Looked at that broadly, animals do the same thing: you give rise to a generation of haploid cells (sperm or eggs) that merge with somebody else\u2019s next generation to form the subsequent generation of diploid humans.\u00a0 It\u2019s only our conceit that makes the human generations more important than the haploid generations; as far as the sperm and egg are concerned, humans are just ways to make more sperms and eggs.<\/p>\n<p>Actual seeds and pollen came even later, with the seed plants called &#8220;spermatophytes&#8221;.\u00a0 That involved several different evolutionary steps, but it started with the charophytes developing specialized male and female gametes.\u00a0 Later, after the development of the other characteristics of true plants (embryophytes).\u00a0<\/p>\n<p>The embroyphytes are actually relatively recent; they evolved on land rather than in the sea. There are some aquatic embryophytes, but in fact they&#8217;ve moved into the sea from land rather than the other way around. They have specialized sex organs, unlike the charophytes, but they don&#8217;t have separate egg and pollen cells.<\/p>\n<p>That was yet another evolutionary step, the spermatophytes, which is what you think of when you say &#8220;plant&#8221;.\u00a0 That happened when some of the plant&#8217;s reproductive system (the rest of the organs) began to encase the fertilized seeds for greater durability, enabling them to spread a lot further inland.\u00a0 They conquered the world.<\/p>\n<p>That&#8217;s why you think of them as &#8220;plants&#8221;, even though there are so many plants without seeds.\u00a0 The charophytes had other descendants that don\u2019t produce seeds, like ferns and mosses.\u00a0 These may actually have derived from the seed plants.\u00a0 Tracing down the evolutionary path is best done with gene sequencing, and while they\u2019re sequencing things as fast as they can it\u2019s still an expensive and time-consuming process.<\/p>\n<p>The upshot is that no, &#8220;seeds&#8221; didn&#8217;t just mysteriously appear one day.\u00a0 The evolutionary history of plants is long and complicated, with a lot of side journeys and dead ends along the way.\u00a0 I&#8217;ve only barely touched on it, what you&#8217;d find in any introductory biology textbook.\u00a0 There&#8217;s a lot more to know about it, but I&#8217;ve let this answer go on long enough.<\/p>\n<\/div>\n<p>&nbsp;<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<div>\n<div><a href=\"http:\/\/askville.amazon.com\/SignIn.do?action=\/plant\/AnswerViewer.do?requestId=9858319\" rel=\"nofollow\">Sign in to report abuse or send a compliment<\/a><\/div>\n<div><a href=\"http:\/\/askville.amazon.com\/UserProfile.do?userId=1234711\" rel=\"nofollow\">PamPerdue <\/a>53 months ago<\/div>\n<\/div>\n<div>\n<div>Please <a href=\"http:\/\/askville.amazon.com\/SignIn.do?action=%2fplant%2fAnswerViewer.do%3frequestId%3d9858319\">sign in <\/a>to give a compliment.<\/div>\n<\/div>\n<div>\n<div>Please <a href=\"http:\/\/askville.amazon.com\/MobileVerificationRequestV2.do?action=%2fplant%2fAnswerViewer.do%3frequestId%3d9858319\">verify your account <\/a>to give a compliment.<\/div>\n<\/div>\n<div>\n<div>Please <a href=\"http:\/\/askville.amazon.com\/SignIn.do?action=%2fplant%2fAnswerViewer.do%3frequestId%3d9858319\">sign in <\/a>to send a message.<\/div>\n<\/div>\n<div>\n<div>Please <a href=\"http:\/\/askville.amazon.com\/MobileVerificationRequestV2.do?action=%2fplant%2fAnswerViewer.do%3frequestId%3d9858319\">verify your account <\/a>to send a message.<\/div>\n<\/div>\n<div>\u00a0<\/div>\n<div>\u00a0<\/div>\n<\/div>\n<div>\u00a0<\/div>\n<div>\n<div>\n<div>\n<table width=\"100%\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td valign=\"top\" width=\"1%\">\n<div><img loading=\"lazy\" src=\"http:\/\/g-ecx.images-amazon.com\/images\/G\/01\/askville\/1234711_profile\/12_1234711_profile._V01__SY65_.jpg\" alt=\"\" width=\"60\" height=\"74\" \/><\/div>\n<\/td>\n<td align=\"left\" valign=\"top\">\n<div>\n<div>PamPerduePamPerdue<\/div>\n<\/div>\n<div><img loading=\"lazy\" src=\"http:\/\/g-ecx.images-amazon.com\/images\/G\/01\/askville\/elements\/bs-loader._V01_.gif\" alt=\"ajax\" width=\"16\" height=\"16\" \/> Loading stats&#8230;<\/div>\n<div>\u00a0<\/div>\n<div><img loading=\"lazy\" src=\"http:\/\/g-ecx.images-amazon.com\/images\/G\/01\/askville\/elements\/bs-loader._V01_.gif\" alt=\"ajax\" width=\"16\" height=\"16\" \/> Loading awards&#8230;<\/div>\n<div>\u00a0<\/div>\n<table cellspacing=\"6\">\n<tbody>\n<tr>\n<td><a href=\"http:\/\/askville.amazon.com\/SignIn.do?action=%2Fplant%2FAnswerViewer.do%3FrequestId%3D9858319\">Sign in<\/a> and you can:<\/td>\n<td>\u00a0Private message<\/td>\n<\/tr>\n<tr>\n<td>\u00a0Become a friend<\/td>\n<td>\u00a0Follow<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n<div><img loading=\"lazy\" src=\"http:\/\/g-ecx.images-amazon.com\/images\/G\/01\/askville\/1234711_profile\/12_1234711_profile._V01__SY65_.jpg\" alt=\"\" width=\"40\" height=\"49\" \/><\/p>\n<div>\u00a0<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><a name=\"answer3\"><\/a><a id=\"response_id_9859478\" name=\"response_id_9859478\"><\/a><\/p>\n<div>Answer from Ancient_Hacker<\/div>\n<div>4 people found this helpful<\/div>\n<div>\n<div>\n<h2 id=\"answer_summary_9859478\">Well&#8230;<\/h2>\n<table width=\"100%\" cellspacing=\"0\">\n<tbody>\n<tr>\n<td colspan=\"2\">\n<div><!--  mywrite content -->Well first you have to define &#8220;Plant&#8221;.\u00a0\u00a0 Let&#8217;s go with a living thing that uses chlorophyll to capture energy.The first &#8220;plants&#8221;
