What is this energy used for in plants?
During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
How does Elodea carry out photosynthesis?
How can I use Elodea to study photosynthesis? During photosynthesis, the plant absorbs carbon dioxide from the water and releases oxygen. Since oxygen is much less soluble in water than is carbon dioxide, the water quickly saturates with oxygen and bubbles form.
How does the structure of the Elodea plant helps it collect energy from the sun?
Plant cells contain chloroplasts, which are round, green organelles that use sunlight to make sugar. (Using sunlight to make sugar is called photosynthesis.) Also, all cells are filled with a jelly-like fluid called cytoplasm. It helps cells move nutrients and chemicals around the cell.
What gas did the Elodea plants release?
carbon dioxide
They produce carbon dioxide during cellular respiration.
How is food converted into usable energy?
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
What do Elodea cells look like?
This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). The central vacuole takes up most of the volume of the cell.
What kind of energy does an Elodea plant need?
The energy source is light energy. Explanation: The greater the distance from the light source, the less production of gas bubbles. Therefore, the Elodea plant needs light energy to photosynthesize. A group of students separated 16 bean plants into four equal groups. They exposed each group to a different number of hours of light.
What is the process of photosynthesis in Elodea lab?
Photosynthesis in Elodea Lab Essay. Elodea & PhotosynthesisPhotosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
Why did I put too much water on my Elodea plant?
Some possible mistakes that could have occurred during this experiment can include the following: Miscalculating the distance between the Elodea plant and the light source. Putting in too much water.Putting in too much sodium bicarbonate.Elodea plant may be dry or not developed.
