Two green plants are kept separately in oxygen-free containers, one in the dark and the other in sunlight. It was observed that plants kept in the dark could not survive longer. Give a reason for this observation.
Question
Two green plants are kept separately in oxygen-free containers, one in the dark and the other in sunlight. It was observed that plants kept in the dark could not survive longer. Give a reason for this observation.
Solution
The reason for this observation is due to the process of photosynthesis. Photosynthesis is the process by which green plants convert light energy, usually from the sun, into chemical energy in the form of glucose or other sugars. This process requires light, carbon dioxide, and water.
In the case of the plant kept in the dark, it does not have access to light, which is a crucial component for photosynthesis. Without light, the plant cannot produce glucose, which is its primary source of energy. As a result, the plant cannot survive for long.
On the other hand, the plant kept in sunlight can perform photosynthesis because it has access to light. Even though both plants are in oxygen-free containers, they can still perform photosynthesis as long as they have access to light and water because oxygen is a byproduct of photosynthesis, not a reactant.
Therefore, the plant in the dark dies sooner because it cannot perform photosynthesis and produce the energy it needs to survive.

Consider the following investigation. A healthy plant is placed in a sealed container overnight when the plant is in darkness. The oxygen concentration in the trapped air is measured at the start of the night and again in the morning.Justify whether the oxygen concentration in the morning will be higher, lower or the same as at night.
All plants give out oxygen during the day and carbon dioxide during night do you agree with the statement give reasons
Can photosynthesis occur if a leaf is placed in the dark?
Plants need light to photosynthesize. With too little light, plants will not have enough energy to survive and grow. However, too much light can damage leaves and slow the rate of photosynthesis.
The dark reactions of photosynthesis are independent of light. However, if plants are deprivedof light, then dark reactions would NOT occur because they need some molecules to proceedwith, which form in the presence of light.These molecules areA. ADP and NADP.B. water and oxygen.C. ATP and NADPH.D. glucose and oxygen
