How do mushrooms grow?

Mushrooms are wonderful plants. They have no roots, stems, leaves. They grow so fast that you think they are growing before your eyes. They belong to the fungal family, so they don't have the chlorophyll to make food for themselves. Some of them are delicacies, while others are so poisonous that to eat them means certain death.

The part of the mushroom that rises above the ground is the edible part. The rest of the plant lies underground as a mass of white intertwined threads. These threads are called mycelium, or mycelium. Mycelial filaments grow out of spores, and spores are tiny, dusty particles that fall from the cap of a fully mature mushroom. Whitish buds appear on these threads in the form of cones, they begin to grow, develop, and eventually they open in the form of an umbrella or other form characteristic of the fungus.

Most mushrooms have small round holes at the bottom of the cap, very close to each other. It is in these holes that spores develop. When ripe, the spores fall out and are carried by the wind. When the spores land on favorable soil, they develop into new fungi. Most mushrooms grow in moist shady forests or in gorges, where there is always a lot of shade, warmth and moisture.

There are mushrooms that, unlike these, grow in open areas, in the sun. But since mushrooms are made up mostly of water, most of them cannot live in dry, hot winds or in the hot summer sun.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Chlamydomonas as a draft force 04.12.2005

Biologists from Harvard University (USA) made the single-celled alga Chlamydomonas carry heavy loads.

Algae, moving with the help of two flagella, swim towards the light. Near the light source, the experimenters placed polystyrene beads coated with a special adhesive that decomposes under ultraviolet light.

When the chlamydomonas touches the ball, it sticks to the algae. The light is turned off and a new beacon is lit at the other end of the aquarium. When chlamydomonas with a load, the mass of which can reach the mass of the cell itself, swims up to the light, they give a flash of ultraviolet light. The load is peeling off. The light is turned on again at the other end of the path, and the empty seaweed is sent for a new load.

So far, this is just an interesting experiment, but in the future, chlamydomonas may serve as assemblers of nanotechnological devices.
