Q1:植物有哪些?


植物包括藻菌类、苔藓类、蕨类和种子类,其中藻菌类植物属于较为原始的低等生物,主要的展现形态是叶状体,苔藓类是一种小型植物,不能独立生存,而蕨类植物的进化水平较高,能够分化出根、茎以及叶。


1、藻菌类植物特征


藻菌类植物大约有三万中,主要生长在淡水或海水中,常见的种类通常有小球藻、团藻和海带,其中小球藻属于单细胞植物,团藻属于群体性植物,而海带呈现叶状体。


2、苔藓类植物特征


苔藓类植物属于进化水平较高的类别,现存种类约有一万两千种,在世界各地均有分布,其中热带、亚热带以及温带的种类较多,苔藓类植物主要吸附在土壤、石头以及部分植物的根部。


3、蕨类植物特征


裸蕨植物是一种体型矮小,结构简单的植物。因无叶而得此名。这类植物曾在距今3.9~3.7亿年前的早、中泥盆纪盛极一时,广布全球,是当时陆生植物的优势种。直到距今3.6亿年的晚泥盆纪才趋于绝灭。


4、种子类植物特征


种子植物(拉丁学名:Spermatophyta),又叫显花植物,种子植物分布于世界各地,是植物界最高等的类群,所有的种子植物都有两个基本特征,就是体内有维管组织——韧皮部和木质部、能产生种子并用种子繁殖。

    浙江" When Branstad was receiving a Chinese trade delegation as Iowa governor in March, he remarked that he would like to be able to enjoy a bite of US beef at the US embassy in Beijing

    省发视防The Chinese Navy's hospital ship Peace Ark arrives on Tuesday in Freetown, Sierra Leone, on an eight-day mission to deliver free medical services to 2,000 people in the West African nation布近The visit marks the first time the ship has visited West Africa, Xinhua said

    浙江省发布近视防控意见

    控意[Photo/Xinhua]The Chinese Navy's hospital ship Peace Ark is providing humanitarian medical services to the people of Sierra Leone during an ongoing port call in the West African nation, Chinese media reported浙江The vessel arrived on Tuesday in Freetown, Sierra Leone's capital and largest city, which is a major port on the Atlantic Ocean省发视防A nurse from China draws blood as part of an examination of a boy on the Peace Ark on Sept 21,2017布近Sierra Leone is the second destination for Peace Ark in its "Harmonious Mission 2017" tour控意Medical personnel began examining and treating local residents immediately, Xinhua News Agency reported

    浙江It carries a total of 115 doctors and nurses, most of them from the People Liberation Army's Naval Medical University and Navy General Hospital省发视防Each day hundreds of Sierra Leone residents line up outside Peace Ark waiting for their turn to be diagnosed by Chinese doctors, the report said, noting that at least 2,000 residents would receive medical services during the ship's eight-day stay in Freetown布近In return, the United States promised not to use nuclear weapons or conventional weapons to attack or invade the DPRK

    控意In the statement, the DPRK reaffirmed its commitment to abandoning nuclear weapons and existing nuclear programs浙江"We believe if the parties concerned can adhere to those consensus, abide by the spirit of the joint statement and seek ways to address the reasonable concerns of concerned parties, we will find a way out," said the spokesperson省发视防Lu said the parties concerned should learn from experience in reaching the agreement, which includes holding that the core of the Korean Peninsula nuclear issue is over security issues, the key lies with the United States and the DPRK, and concerns of all parties should be resolved in a balanced way布近BEIJING -- China said Tuesday that the six-party talks are still an efficient platform to address the Korean Peninsula nuclear issue

    Launched in 2003, the six-party talks were suspended in December 2008Lu said the joint statement, signed on Sept 19, 2005, is the most important progress in addressing the Korean Peninsula nuclear issue through negotiations, and is of milestone significance

    浙江省发布近视防控意见

    China also proposed a dual-track approach to denuclearization on the peninsula on the one hand and establishing a peace mechanism on the otherChina has put forward the "double suspension" proposal, which requires the DPRK to suspend its missile and nuclear activities in exchange for the suspension of large-scale US-ROK military drillsThe DPRK walked out of the talks in April 2009 in protest against UN sanctionsAbe, who also heads the LDP, is set to provisionally dissolve the lower chamber of Japan's bicameral system of parliament on Sept 28, as this is when the extraordinary Diet session will be convened, according to LDP sources close to the matter

    However, the prime minister has the authority to dissolve the lower chamber and call a general election at willThis scenario would see official campaigning for the national poll kick off on Oct 10, with voters thereafter casting their ballots on Oct 22A lower house election must be held by December 2018 as this is when the four-year terms of current lower house lawmakers expireIf Abe goes ahead with his plan to call a snap election, then three by-elections that have been slated to take place on Oct 22 would be replaced by the general election

    The opposition camp, however, has criticized Abe's move to call a snap election, with some accusing him of merely trying to escape from the influence-peddling scandals he is currently implicated in and engineering his stay in power"Nikai on Tuesday, during a meeting of ruling LDP executives reportedly conveyed Abe's intentions and relayed the party's determination to get all of its candidates fielded in the race

    浙江省发布近视防控意见

    Prior to Abe's departure Monday for a five-day trip to New York to attend the UN General Assembly, Abe told Nikai during a meeting that he "will decide on the timing of the snap election after returning from the UN General Assembly on FridayAbe last dissolved the lower house of parliament in November 2014 and thereafter led the ruling coalition to a sweeping victory in the following election in December

    In addition, the fact that new opposition parties in the process of being formed will not have time to organize themselves and mount a serious challenge to Abe and the LDP in such a short space of time, has made many political watchers question Abe's regard for democracy and the will of the peopleTOKYO - Japanese Prime Minister Shinzo Abe is gearing up to dissolve the lower house of parliament and call a snap general election, Liberal Democratic Party (LDP) Secretary General Toshihiro Nikai confirmed on TuesdayThe support rate for Abe's cabinet has improved moderately recently, and the opposition camp has accused the prime minister of taking advantage of this and have slammed the possible general election as being unnecessary and serving Abe's personal, not political objectivesThe application for UNESCO heritage status submitted by more than 10 groups from China, the Republic of Korea and other countries and regions will "allow the world to fully understand the brutality of the war of agrression, remember history, cherish peace and defend human dignity," Chinese Foreign Ministry spokesperson Lu Kang said at a regular news briefingBEIJING -- Japan should act correctly towards an application for records of comfort women to be listed as UNESCO heritage, instead of threatening not to pay its UNESCO membership fees, a Chinese spokesperson said MondayIf the submitted documents are approved for the UNESCO Memory of the World Register next month, domestic pressure for Japan to cancel payment of its UNESCO membership fees will grow, according to Japanese media

    "The members of international organizations are obliged to pay their membership fees on time and in fullChina demands Japan reflect on its history of aggression, and take a correct attitude towards and do not smear or meddle with the application," Lu said

    The move serves the purposes of the UNESCO, he saidForceful recruitment of comfort women, or sex slaves, was a grave crime committed by the Japanese militarism during WWII

    There is solid evidence and no room for denying that, Lu saidHe said that Japan should handle the issue properly and in a responsible way to gain trust from its Asian neighbors and the international community

    People from the DPRK and the ROK belong to the same ethnic group, and China has always supported the two countries in strengthening exchanges, improving ties and promoting reconciliation, he saidLu's comment came after ROK President Moon Jae-in suggested that his country could go ahead with humanitarian aid to the DPRK "regardless of political situations," despite Japanese Prime Minister Shinzo Abe's request for consideration of the timing of the proposed aidBEIJING -- China hopes that concerned parities can understand and respect the emotions of the people and support normal exchanges between the Democratic People's Republic of Korea (DPRK) and the Republic of Korea (ROK), Foreign Ministry spokesperson Lu Kang said Monday"All the UN Security Council resolutions that imposed sanctions on the DPRK, including the newly adopted Resolution 2375, have stated clearly that they are not intended to have a negative effect on the livelihoods and humanitarian needs of the people there," Lu said at a daily press briefing

    "I think this is not only good for China, but will also be a positive influence to the whole international system," he saidFor example, Singapore can become a launchpad for Chinese companies to march into international markets, and they can make the best of Singapore's trade and service facilities as a financial center and transport hub

    Singapore's cooperation with China concerning the Belt and Road Initiative, Lee said, is focused on infrastructure inter-connectivity, financial projects and third-country programs such as personnel training, which Singapore believes can combine advantages of both sidesThe two sides are expected to exchange views on bilateral ties and issues of common concern, the Chinese Foreign Ministry announced Friday

    In the interview, Lee said the Initiative-related cooperation in sectors such as infrastructure investments, trade and tourism can help further "integrate China into regional and international economic systems while greatly boosting the prosperity and development in other countriesThe Belt and Road Initiative, put forward by Chinese President Xi Jinping in 2013, is aimed at building the Silk Road Economic Belt and the 21st Century Maritime Silk Road through concerted efforts of all related countries to benefit all participants by promoting unimpeded trade, financial integration, infrastructure inter-connectivity and closer people-to-people exchanges

    The Singaporean leader will pay an official visit to China on Sept 19-21 at the invitation of Chinese Premier Li Keqiang"The Initiative will help foster closer cooperation among China and its neighboring countries as well as its trade partners in Europe, Asia and even Africa," he added"We deem the Belt and Road Initiative as positive," Lee said Saturday in an interview with Xinhuanet, Xinhua's official website, noting that China's continuous economic growth has made China an increasingly larger and more important part in the international systemSINGAPORE -- Singaporean Prime Minister Lee Hsien Loong has said that the Belt and Road Initiative of China is positive to the world since it can help further integrate China into regional and international economic systems while boosting growth in other countries

    " In his opinion, the Initiative can help China make more and better contributions to global economic and trade cooperation as well as the international relationsOne option is to hold a snap election on Oct 22, when three by-elections are scheduled, the sources said

    TOKYO - Japanese Prime Minister Shinzo Abe is considering calling a snap election for as early as next month to take advantage of his improved approval ratings and disarray in the main opposition party, government and ruling party sources said on SundayOther possibilities are later in October or after an expected visit by US President Donald Trump in early November

    "Until now, it appeared the election would be next autumn, butAbe's ratings have recovered to 50 percent in some polls
