What two plants have no true stem or roots or leaves?
Algae and mosses are two examples of plants that can lack true stems, roots, and leaves. These plants typically have simple structures that allow them to absorb nutrients and carry out photosynthesis.
How is mass conserved during the process of photosynthesis?
During photosynthesis, plants use carbon dioxide from the air and water from the soil to produce glucose and oxygen. The mass of the carbon atoms from the carbon dioxide that gets converted into glucose is conserved. Therefore, overall mass is conserved during photosynthesis by following the law of conservation of mass.
Which scientist concluded that most of the growing plants mass comes from water?
Jan Baptista van Helmont, a Flemish chemist, physician, and physiologist in the 17th century, conducted an experiment where he grew a willow tree in a weighed amount of soil and water, finding that the increase in mass came primarily from water, not soil nutrients. This led him to conclude that most of the plant's mass comes from water.
What is the changes of the eggs mass in term of osmosis?
When an egg is placed in a hypertonic solution (higher solute concentration outside the egg than inside), water will move out of the egg through osmosis, causing the egg to lose mass. Conversely, if the egg is placed in a hypotonic solution (lower solute concentration outside the egg than inside), water will move into the egg through osmosis, causing the egg to gain mass.
What two pieces of evidence did van Helmont use to reach his conclusion?
Van Helmont used the increase in mass of the willow tree and the water it was given as evidence to conclude that plants do not solely grow by taking up soil. This experiment led him to propose that plants primarily derive their nutrients from water.
Jan van Helmont concluded that plants gain most of their mass from what?
Its water :) Good luck :)
Jan Can Helmont concluded that plants gain most of their mass from where?
From water(It was Jan Van Helmont not Jan Can Helmont)
If you put a carrot in water will it gain or lose mass?
if anything it would be reasonable to expect it to lose mass.
What was the initial working hypothesis for how plants gained mass?
Plants gain mass by taking in nutrients from their roots. They gradually add more stem and leaves.
What was wrong with helmonts conclusion that when plants grow their increase in mass comes from water?
Increase of mass from water. Actually increase in mass is the result of increase in organic matter instead of water.
Does drinking of cold water help gain weight?
Temporarily by the mass of water drunk. This soon lost again.
How can the mass of a sample of water be increased?
i dont know figure it out yourself
What causes the mass of a plant to increase over time?
The mass of a plant increases over time primarily due to the process of photosynthesis, where plants use sunlight, water, and carbon dioxide to produce glucose and store it as energy. This leads to the formation of new plant cells and tissues, resulting in growth and an overall increase in mass. Water uptake from the soil also contributes to the plant's mass gain.
What does not gain or lose mass?
Energy does not have mass. It can be converted into mass (such as in nuclear reactions) or from mass (as in matter-antimatter annihilation), but the energy itself does not gain or lose mass.
Can you use hot water in mixing the serious mass weight gain supplement?
It is not recommended to use hot water when mixing Serious Mass weight gain supplement as it can potentially denature the protein in the supplement. It is best to use cold water or milk to mix the powder for optimal results.
Do potato cubes gain or lose mass in salt water solutions?
depends on the salt content of the potato and how concentrated the salt is. the more salt there is in the water than the potato- the more water will exit the potato which then loses mass.
What makes an egg soaked in water get bigger?
Eggs soaked in distilled water will gain mass and appear dramatically swollen. Eggs in dilute salt solutions will gain mass, and even those in very concentrated solutions might gain mass. Eggs buried in salt or other dry media should lose mass.
