    From this video, I would like to summarise that scientists wanted to prove that plants have animal-like behaviours, they have their own self-defence strategy and also they have their own secret social life which interacts with other plants.
    Plants do not have eyes or ears neither brain but they are smart enough to find their own sources of food. They also communicate and cooperate with each other to find sources together. So here comes a question, do plants behave like animals? Researchers and scientists proved that plants do behave just like animals do. Plants move (roots, stems and shoots) might as well as animals. To be simplified, it is called “Growth”. Plants response to stimuli such as sunlight, and it fights for light to grow through photosynthesis. Another example for an animal-like behaviour was that the root of a plant. All plants have complex eating behaviour. Plants do not just need light to thrive but also nutrients and food in the soil. 80% of the total mass of plants lives below the ground. Concentrate on the roots of the plant, it is more animal-like compared to the stems and shoots. How they do it? How they can search food under the ground? The roots of the plants will thrive downwards due to the gravity force attracted and extend to its maximum until it has already found the most suitable and nutritious condition inside the soil. Same goes to the animals like grizzly bears, they keep moving forward and searching for its prey in order to survive and grow. When it found its favour place and sources, it stops, stays and lives.
    How do plants have their own self-defence strategy? There are two ways. One is that plants interact and find another host plants. Plants compete each other for food. But sometimes there are limitations of food sources. For example, plants need nutrients and water to grow and stay alive. But with too much competitions, both parties will die or have no benefits. To prevent this from happening, they will find a host from another type of species of plants which that might attract them to host them. There is a scientifically prove that plants feast on a host is actually depends on the scent of that plants released. This reaction is between both plants. In other ways, it is a relationship between plants and organisms such as insects. Insects feast on leaves of a plant and plants will defend and protect themselves by providing signals to another predators to go against that enemy. The signals given is very unique which is that the plants will produce green leaf volatile (a type of chemical scent or gas which will be released into the atmosphere when they breathe). When this happened, the scent will attract the predator of that insects to attack them.
    Last but not least, plants have their secret social life and interact with each other. There is a statement stated by researches and scientists that stranger grows more roots to compete food while siblings politely restrain their root growth. There is an evidence of family (plants or trees) sharing resources. There is an experiment did by scientists that they wrapped a leaf of a big tree by using a plastic and injected carbon because plants need carbon to undergo some processes. The carbon only injected on that tree but not the others. And few days after, they detected that the percentage of the carbon of that plants reduces but as for the surrounding of other small plant trees, the percentage of the content of the carbon is more than the originally injected tree. So it was proved that plants do act like a family by sharing its resources to help others to grow.
    In a conclusion, plants have a very complex ecosystem. Plants do behave like animals. Not all plants are selfish and competitive but some still are very considerate and sharing.

    Dokumentari ini menceritakan tentang tingkahlaku dan bagaimana tumbuhan berkomunikasi antara sesama tumbuhan. Tingkah laku tumbuhan ditakrifkan sebagai tindak balas morfologi atau fisiologi pesat kepada peristiwa-peristiwa yang berlaku disekeliling, berbanding dengan jangka hayat seseorang individu. Darwin merupakan ahli biologi telah menyedari bahawa tumbuh-tumbuhan bertindak tetapi ia telah di bawah fenomena dihargai.

    Tingkah laku tumbuhan dikaji melibatkan makanan, cahaya, nutrien, dan air yang membolehkan semua tumbuhan mendapatkan semua sumber-sumber ini. Tumbuh-tumbuhan juga dapat menyesuaikan banyak ciri pembiakan dan pertahanan sebagai tindak balas kepada kepelbagaian alam sekitar dalam ruang dan masa. Banyak tingkah laku tumbuhan bergantung kepada meristems aktif lelaran yang membolehkan tumbuh-tumbuhan untuk cepat berubah menjadi pelbagai bentuk. Kerana pembinaan modular ini, banyak respon tumbuhan setempat walaupun tahap integrasi dalam tumbuhan keseluruhan tidak difahami dengan baik. Tingkah laku tumbuhan telah disifatkan sebagai lebih mudah dan terbaik. Tumbuh-tumbuhan dapat menjangkakan keadaan masa depan dengan tepat dan bertindak balas terhadap isyarat alam sekitar yang berada di sekelililng mereka. Tumbuhan mempamerkan memori, mengubah tingkah laku mereka bergantung kepada pengalaman sebelum mereka atau pengalaman ibu mereka. Cara tumbuh-tumbuhan berkomunikasi dengan tumbuhan lain ialah mereka mengeluarkan isyarat yang menyebabkan reaksi diramalkan dalam tumbuhan lain dan bertindak balas terhadap isyarat itu sendiri. Tumbuh-tumbuhan juga berkomunikasi dengan tumbuhan lain walaupun dengan tumbuh-tumbuhan daripada spesies lain melalui rangkaian bawah tanah kompleks yang termasuk rhizosphere (akar) tumbuh-tumbuhan, pelepasan udara (gas-gas yang tidak menentu yang dipancarkan oleh tumbuh-tumbuhan) dan rangkaian miselium dalam tanah. Tumbuhan mempamerkan banyak satu tingkah laku yang sama seperti haiwan walaupun mereka tidak mempunyai sistem saraf pusat. Kedua-dua tumbuhan dan haiwan menghadapi ruang dan terbatas masa persekitaran berlainan dan kedua-duanya telah berkembang sistem tindak balas yang positif.

    Kesimpulannya, tumbuh-tumbuhan juga merupakan ciptaan Tuhan yang sepatutnya kita hargai dan sayangi.
