What is spread by what?

Question 1: What spreads seeds through wind (dandelion), insects (pollen) and water (Ceratophyllum)? There are also their own explosions (beans). Man-made transmission, animals carry (Xanthium sibiricum), information: flies, do you know the mystery of catkins flying in spring? Grab a group of catkins and observe carefully, and you will find some small particles inside, which are willow seeds. Willows spread their seeds far away to settle down through flying catkins. Also flying are the seeds of poplar and dandelion. You see, this plant belonging to Cucurbitaceae has formed a small "melon" with burrs. When the melon is ripe, it will fall off at the slightest touch, and the seeds in the melon will gush out from it with mucus, which can reach five meters. You may have seen the plant Xanthium sibiricum. Whenever its fruit matures in autumn, it will find opportunities to firmly hook people or animals that meet it and take the opportunity to travel far. If you look closely, you will find that there are barbs at the top of its bristles, and you have done your duty for its seed spread unconsciously. Some plants spread seeds by mechanical means, and Oxalis is one of them. It is a very common wild weed with small yellow flowers or small red flowers. After the flower, it has a pentagonal capsule. When it ripens, the fruit splits along the back of the chamber, the shell shrinks and the seeds pop out. The fruit of Impatiens balsamina will also crack, which is more severe than oxalis, and it is another example of mechanical seed transmission.

Question 2: What spreads seeds by what? Dandelion spreads seeds through the wind.

Question 3: I also know how to spread seeds. There are many of them.

1, spread by water

Coconut: spread by water. When the coconut is ripe, it falls into the sea and floats away with the sea water.

Water lily: The fruit of the water lily sinks to the bottom when it matures. After the pericarp decays, the seeds covered with spongy exocarp will float and drift to other places.

2, spread by birds or other animals

Cherry, wild grape, wild ginseng: Birds or other animals eat seeds in their stomachs, but because they can't be digested, they are discharged with feces and spread in all directions.

Pine nuts: They were taken away by squirrels when storing winter grain.

3, spread by the wind

Hongliu: It is the flying catkins that spread seeds far away.

dandelion

There are many ways to spread seeds mechanically.

Impatiens: The fruit of Impatiens will bounce off, crack and shoot a bullet in all directions. This is a method of mechanical sowing.

There are many legumes that spread seeds by machinery.

1, dandelion seeds spread by wind,

2. Aquatic plants such as lotus root spread through water and aquatic animals, and coconuts also spread through water.

3. Xanthium sibiricum, Bidens bipinnata and so on. When animals pass by, they are spread on animal fur by adhesion.

4. The fruits of some plants are delicious, but their seed coats are relatively corrosion-resistant. They are usually mixed into animal excreta through the intestines and stomach of animals to achieve the purpose of transmission, such as watermelon, melon and Ligustrum lucidum.

5. There are also some plant fruits with strong ejection ability, which can eject seeds to distant places for reproduction, such as impatiens and tropical plants.

Question 4: What spreads seeds and flowers through butterflies?

Question 5: What are the ways of network communication?

1, online media (national comprehensive, local and industry vertical media)

2. Network community (BBS).

3. Search engines (Baidu, Google, Soso, sogou)

4. Weibo, an online blog,

5. Video sharing website

6. Social networking sites (blogosphere, social circle)

7.IM (Instant Messaging Tool)

8. Digital reading

9. E-mail.

Question 6: 1, what is communication? What are its basic characteristics? 1. Information dissemination is a two-way direct communication between members of small groups.

2. Group communication plays an important role in the formation of group consciousness. The stronger the group consciousness, the stronger the cohesion of the group, and the more conducive to the realization of the group goals.

3. The consensus formed in group communication will produce group tendency, and this group pressure can change the different opinions of individuals in the group, thus producing herd behavior.

4. "Opinion leaders" in the group can guide people's cognitive and behavioral changes, and are often the starting point of healthy communication.

Question 7: What is the major of communication? This major is based on humanistic tradition, with solid basic knowledge and broad humanistic vision. Based on reality, the course not only emphasizes practical content, establishes close contact with various media, but also highlights academic background, broadens international horizons, and combines theory with practice to form a news communication education system with China characteristics, so as to cultivate journalists with profound humanistic accomplishment and meet the needs of the industry. After graduation, students can widely adapt to the different needs of various media, undertake news, editing and management work in newspapers, magazines, radio and television, internet and other departments, and also adapt to the news propaganda and public relations work of party and government organs at all levels and departments at all levels.

The core courses of this major include: introduction to journalism, introduction to communication, introduction to network communication, introduction to visual communication, news interview and writing, in-depth reporting, research on TV program form, audio-visual language, news photography, picture editing and layout design, media social history, humanistic reading, literature appreciation, mass communication, etc. During the study period, experts and scholars at home and abroad will be invited to give lectures, and students will be organized to practice in various media units to improve their comprehensive quality and practical ability.

Question 9: How does elm spread? The seed of elm is samara, which is mainly spread by wind.

Elm (scientific name: elm): also known as spring elm and white elm. , commonly known as "elm pimple", is a deciduous tree of Ulmus, with smooth bark of young trees, grayish brown or light gray, dark gray bark of big trees, irregular deep longitudinal cracks and rough epidermis; Branchlets glabrous or hairy, without swollen cork layer and raised cork wings; Winter buds are nearly spherical or ovoid. Leaves are oval, oval, etc. The leaves are smooth and hairless, the back of the leaves is pubescent when they are young, then they become hairless or some veins have tufted hairs, and the petiole surface is pubescent. Flowers bloom first, and they cluster on the leaf arcs of branches. Samara sparsely obovate, rounded. The flowering and fruiting period is from March to June (later in Northeast China).
