Where does a plants mass come from worksheet
Vascular plants = winning! – crash course biology #37
Students do research into plants in the light and dark, as well as mass transitions. The aim of this lesson is for students to make observations and gather data to support their explanations in Lessons 4 and 5.
In Lesson 3, you have the option of taking one of two paths. Please refer to the Front Matter for the Plants Unit and/or the Context Information section below for more information before making this instructional decision.
Students make assumptions about how they will use their investigation tools—digital balances and BTB—to detect movements and changes in matter by creating theories about how matter moves and changes, as well as how energy changes, when radishes move and grow.
Students (a) create evidence-based arguments about how matter moves and changes, and how energy changes, as plants grow, shift, and work, using data from their investigations; and (b) recognize unanswered questions about matter movement and change that the data are inadequate to resolve.
This lesson gives students opportunities to observe and collect data, which will help them create theories about photosynthesis and cellular respiration in the next lesson. They’ll notice that plants “breathe” (exchange gases with air) in various ways in the light and in the dark.

Have you ever thought about where trees get their mass? One of the more common responses, as seen in a 2012 video, is that a tree’s mass (increasingly larger size) is derived from the soil. Isn’t that reasonable? After all, we’ve been told that plants need soil (improved “dirt”) to survive. Problems usually occur when asked to clarify why there isn’t a wide hole around a tree, according to Michigan State University Extension. There must be less soil around the tree if it is using soil. However, studies show that the amount of soil in a pot when a seed is planted is nearly equivalent to the amount of soil in the same pot when the plant from that seed is harvested. So, where does all this weight come from?
Carbon makes up the bulk of a tree’s mass. The carbon comes from the photosynthesis of carbon dioxide. Plants transform the sun’s energy into chemical energy, which is trapped within the bonds of carbon molecules formed from atmospheric carbon dioxide and water during photosynthesis. Yeah, carbon dioxide in the air we breathe ends up in “food” molecules (called glucose), each of which has six carbon atoms (and 12 hydrogen atoms and 6 oxygen atoms).

The Union of Concerned Scientists contributed to the creation of A Balanced Concept of Renewable Biomass, which are practical and efficient sustainability requirements that can help ensure that woody biomass harvests are sustainable.
In the Green Mountain State, there’s a lot of green energy.
In 1998, the first biomass gasification plant in the United States opened near Burlington, Vermont. The Joseph C. McNeil Generating Station generates about 50 megawatts of electricity from low-quality trees and harvest residue, which is nearly enough to power Burlington, Vermont’s largest city.

The massive Beijing Deqingyuan chicken farm, located outside of Beijing, China, produces 220 tons of manure and 170 tons of wastewater per day. The farm will turn chicken manure into 14,600 megawatt-hours of electricity per year thanks to GE Energy’s gasification technology.
While meanings vary, a group of trees and shrubs that have not been harvested for timber or other purposes in about 200 years. A primeval forest is also known as a primary forest, primal forest, or ancient woodland.
The simple story of photosynthesis and food – amanda ooten
Photosynthesis is the conversion of light energy into chemical energy through a sequence of chain reactions. Photosynthesis also results in the production of energy-dense carbohydrates such as starch. The chloroplast of a plant cell is where photosynthesis takes place… more
Have you ever wondered how plants grow so big? All of those leaves and branches had to come from somewhere, so where did they come from? Water, air, and energy appear to be the most important factors in plant development.
Oxygen and carbon dioxide are two compounds contained in air. You might believe that oxygen is the most essential molecule since we need it to live. Carbon, on the other hand, is crucial. Carbon is present in all living things on the earth.
Nitrogen, oxygen, and carbon dioxide make up the bulk of air. So, how do plants obtain the carbon they need to thrive? They take in carbon dioxide from the atmosphere. Carbon is the most common building material used by plants to create new leaves, stems, and roots. Carbon dioxide also provides the oxygen needed to build glucose molecules.
Water is another essential element for plant growth, which they obtain by absorbing it through their roots. Two hydrogen atoms and one oxygen atom make up water. Water contains hydrogen, which is used to assist in the creation of glucose molecules.
