What did the experiments of van Helmont Priestley and Ingenhousz reveal about how plants grow?
Van Helmont proved that soil was not responsible for a tree's increase in mass by doing an experiment with a willow tree. He found that the tree grew by 74.4 kg without a comparable decrease in the soil's mass. Priestly discovered that plants release a gas into the air that supports combustion. Ingenhousz discovered that the plant in Priestley's experiment is depended on light and that the gas released by the plant is oxygen. Carbon dioxide was the source of carbon in plants.
What do conifers eat?
Conifers are trees. They derive nourishment from the soil .
Did van Helmont's experiment supports or disprove Aristotle's hypothesis?
His data contradicted Aristotle's hypothesis that a plant gains mass from soil.
Which type of soil do bean plants grow the best in?
in clay soil or wet soil has diameter of 0.22mm to 0.66mm
How are plants that are grown in poor soil likely to differ from plants that are grown in good soil?
Good soil has a lot of good nutrients that your plants need. Poor soil usually lacks nutrients for the plants so the difference is great. Good soil: The leaves will be nice and green, ( if you water it well) Poor soil: they will be yellow Good soil: The produce will have out bursting flavor. Poor soil: It will be tasteless.
What did van helmont discover plants?
Van Helmont proved that plants got most of they're mass from water and nutrients in the soil. he also proved that plants release a combustible gas.
Which scientist concluded that most of a growing plants mass comes from water?
Jan Van Helmont. in his 5-year experiment he planted a seedling in soil and watered it. it grew to a small treegaining 75kg. mass of soil didn't change. since water was all he added, he concluded it was from the water. - from Prentice Hall Texas Biology Book (9th grade)
Who measured the mass of the soil in which a plant grew?
Van Helmont
How else does soil help plants?
Soil is essential to most plants because it provides the plant with food, water, vital minerals, nutrition and nourishment that the plant needs in order to survive.
Who discovered that most of plant biomass does not come from the soil?
Von Helmont
What scientist measured the mass of the soil in which a plant grew?
Van Helmont

What is the importance of soil to living organisms?
Soil incorporate many essential macro and microelements and nourishes the plants and microbes. The plants and microbes, on the other hand, provide nourishment to the animals. Thus the entire living world is dependent on soil (directly or indirectly) for availability of essential elements.
What conditions relate to the research of van Helmont?
He grew a willow tree in a carefully weighed amount of soil. He noticed that little of the soil was consumed, but that the weight of the tree greatly increased. He concluded that the extra weight came from the water. His willow tree experiment was one of the first to use quantitative measurements. Van Helmont wanted to understand digestion chemically, believed all substances could be reduced to air and water, and thought that acid/base reactions were fundamental.
What plant grow in peat soil?
Plants that like acidic soil or that rely on other ways of nourishment, like the Sundew, with its sticky leaves, which catches and lives on insects.
How was the way plants feed discovered?
Aristotle was a Greek scientist who thought that plants ate soil and sucked it up through their roots. Most people believed this until the 17th century. In the 17th century, a scientist called Jan van Helmont tested Aristotle's theory. He measured the masses of a small tree and some soil in a pot. He planted the tree and watered it for 5 years In van Helmont's experiment the mass of the soil did not go down much (0.06kgs/ 0.132lbs) but the mass of the tree went up a lot (74.47kg/163.834lbs). This showed that Aristotle's theory was wrong. Van Helmont suggested that the tree got all of its food from water. In 1782, Jean Senebier showed that plants need carbon dioxide gas from the air and suggested that plants only use this gas to make food. In 1804, Nicholas de Saussure did van Helmont's experiment again, but he carefully measured the amounts of carbon dioxide and water he gave to the plant. He showed that both carbon dioxide and water are needed.
What was the living tree experiment?
The "living tree" experiment was a scientific study performed originally by Jan Baptiste van Helmont (1580-1644) and thereafter repeated by several other scientists in the decades and centuries following. Van Helmont measures the weight of the tree at the start of the experiment (five pounds) as well as the weight of the soil (200 pounds). After five years of regularly watering the tree, van Helmont noted that the soil only lost about 2 ounces of weight while the tree weighed an astonishing 164 pounds. He concluded that because the tree did not gain all this weight from the soil, it must have gained it from the water intake. Although we now know that plants gain much of their mass from photosynthesis/carbon dioxide as well as soil, van Helmont's experiment has been lauded as an early example of strict attention to detail and experimental controls.
