Why we Cannot conduct an experiment on plant respiration during day time?
Answer: We cannot conduct an experiment on plant respiration during daytime because during daytime they carry out photosynthesis and thus the carbon dioxide is released during respiration gets absorbed during photosynthesis and the oxygen released during photosynthesis gets absorbed during respiration.
Does respiration occur only at night or the entire day?
When does respiration occur in plants? It is a common misconception that photosynthesis occurs during the day and respiration only happens at night. In fact, respiration in plants occurs all the time – both day and night, as respiration in plants is like breathing in humans.
What is the purpose of the cell respiration lab?
Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple: it provides cells with the energy they need to function.
What is the difference between photosynthesis and respiration?
While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
Why is it not possible to observe respiration in a green plant kept in the sunlight?
When a plant is kept in sunlight, CO2 released by respiration gets used by photosynthesis to synthesize food. So no carbon dioxide is liberated, and respiration cannot be demonstrated.
Why is respiration said to be the reverse of photosynthesis?
Respiration and Photosynthesis are almostopposite processes because photosynthesis removes carbon dioxide from the atmosphere while respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it’s waste product of carbon dioxide (CO2).
Why does respiration occur at night?
Dark – Only respiration takes place. Oxygen is consumed while carbon dioxide is released in plant respiration at night. Bright sunlight – Photosynthesis uses carbon dioxide and makes oxygen faster than respiration produces carbon dioxide and consumes oxygen. Extra oxygen is released into the atmosphere.
Why is cellular respiration a vital process for all cells?
Cellular respiration is important because it provides the energy for living organisms to perform all of the other necessary functions to maintain life. Glycolysis breaks down glucose and releases ATP for cellular respiration.
Where does cellular respiration occur within the cell?
While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.
In what part of the cell does photosynthesis and respiration occur?
mitochondria
Photosynthesis occurs in the chloroplasts, whereas cellular respiration occurs in the mitochondria. Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration.
Which experiment will demonstrate the production of carbon dioxide in aerobic respiration?
Experiment to demonstrate the production of carbon dioxide in aerobic respiration: Bottle, germinating seeds, cork, stopper, glass tube, water, wide-mouthed tube with a stopcock, lime water. 1. Take a wide-mouthed bottled and place some germinating seeds in it.
Why is there no respiration in the first apparatus?
In the first apparatus there is no change because the respiratory susbstrates, i.e., seeds, are dry and not respiring. If the respiration would have been there the CO 2 released would have been absorbed by the caustic potash. Thus, ultimately the solution must have rushed into the tube of retort. So, there is no respiration.
How do you measure cellular respiration in a lab?
Measuring carbon dioxide production is an indirect way of measuring whether or not cellular respiration is occurring. Your task in this lab is to determine whether or not various sets of bean seeds are going through cellular respiration. Fill one flask about 1/3 full of the bean seeds labeled “Germ.”
Is respiration a physical or chemical process?
When you breathe, you are taking in oxygen with each inhale and releasing carbon dioxide with each exhale. This gas exchange is important for respiration, but while breathing is a physical process, respiration can be thought of as more of a chemical process. All organisms, from a single bacterial cell to a coral reef colony…
