Plants are another perspective for us humans to understand and explore the world. In their own world, their growth, blooming, fruiting, withering and prosperity, and their life processes are all very clearly visible. However, some of the characteristics they have developed in order to survive really feel like their ultimate secret. This kind of life process is very clear. This phenomenon makes us humans feel inferior and can be called miraculous.
, A single tree makes a forest
We have an old saying, "A single tree does not make a forest", that is to say, an ordinary tree can only be a tree and can never become a forest. But in tropical areas, there is a Tree can make this sentence untrue, that is banyan tree . We know that the aerial roots of the banyan tree are very developed and have very strong vitality. As long as they can touch the ground, they can penetrate deeply into the soil and become new trunks. The bigger the tree, the more trunks these aerial roots turn into. In addition to normal absorption of nutrients, they also have a function of supporting the huge crown of the banyan tree. The larger the crown, the more aerial roots. Naturally, the trunk will also When there are more trees, the canopy will increase. This is a cycle, and gradually a single tree becomes a forest.
. Plant killers
In tropical rainforests, plant killers can be found everywhere, especially Ficus plants. Their unique aerial roots are the killer tools. These aerial roots will attach to other big trees. These aerial roots along the They extend upward or downward along the trunks of other big trees, intertwined together, and finally become a network, wrapping the trunks of other big trees. These aerial roots will also penetrate into the soil, robbing water and nutrients. Above the ground, the network of aerial roots will compete for space and sunlight, which can effectively block the growth of the big tree. Eventually, the big tree will die, and the remains of the big tree will be used as a tree by the aerial roots of the ficus plant. Nutrients are slowly absorbed.
. Carnivorous plants
Ficus plants can kill the big trees around them over time. Some plants, like animals, can hunt, as long as they catch mosquitoes, insects and other small animals, they are also called carnivorous plants . They mainly accomplish hunting through their own special structure, and then rely on their own secreted digestive enzyme and bacteria to complete decomposition and absorption. This type of plant needs to kill animals to maintain the absorption and growth of nutrients. Naturally, it can only be seen in areas with relatively poor nutrients, or in areas lacking nitrogen element . These predatory plants can often be seen in swamps and desert areas. Our common flytrap is one of them, as well as pitcher plant , Sarracenia and so on.
. Symbiotic plants
Anyone who lives in rural areas or has grown crops knows one thing. When planting soybeans, there is no need to fertilize or fertilize too much. This is because something called rhizobia will grow on the roots of soybean flour . This is a rod-shaped bacterium with a long flagellum. It can invade from the root hairs of leguminous plants into the inside of the rhizome, forming many nodule. These root nodules have a symbiotic relationship with soybeans. They can absorb nutrients and water like roots, and can also absorb free nitrogen in the air and solidify it into nitrogen fertilizer that plants need. To put it simply, soybeans provide carbohydrates to rhizobia, and rhizobia provide nutrients and moisture to soybeans, especially nitrogen that ensures the growth of soybeans.
5, self-protection ability
can also be called the defense ability of plants. In nature, plants will face various challenges at any time to survive. In the long process of survival competition, various abilities have gradually evolved. The defense ability that allows plants to survive allows plants to play a certain defensive role when attacked by foreign objects.For example, plants containing toxins are the most common means of defense and are also very powerful in self-protection. There are also some plants covered with spikes, and some mimic plants that can grow into various scary postures. These are effective means for plants to defend themselves against foreign enemies.
6. Sleep needs
We know that both humans and animals need sleep, which can quickly replenish the energy and physical energy consumed every day. What we don’t know is that plants actually need sleep too. Plants have a phenomenon that scientists call "sleep movement." By observing the leaves and flowers of plants, we can find that the leaves or flowers of plants always open during the day and close at night, or close during the day and open at night. This is the "sleep movement" of plants. Like albizia tree , water lily , sorrel and so on, they are all flowers with obvious "sleep movement". This phenomenon is mainly to reduce its own heat loss and water evaporation, and is a kind of self-protection.
Conclusion:
In the magical nature, magical plants also have many magical phenomena that we need to discover, such as the epiphytic phenomenon, that is, some plants are attached to other plants, the root phenomenon Because the higher they grow, the original normal root system gradually turns into a plate-like root system, which penetrates deeply into the ground and becomes stronger, etc. There are many more. If you are interested, I will chat with you next time. I’m here first. It’s Xiaogui, thank you all!
