why carbon dioxide nessary for plant . and what is used to remove the carbon dioxide in bell jar expirement
Answers
Answer:
Plants carry out photosynthesis to make food from the raw materials they gather from their environment. We can investigate the conditions needed for this process and the factors which affect its rate.

Does a plant need carbon dioxide for photosynthesis?
To investigate if a plant needs carbon dioxide for photosynthesis, we need to create conditions for the plants where carbon dioxide is present in one test and absent in another. The air contains 0.04% carbon dioxide. Scientists can use sodium hydroxide to absorb carbon dioxide from the air so that it is unavailable for the plants to use in photosynthesis.
Question
In this particular experiment, a de-starched plant is covered using an airtight transparent plastic bag. The chemical sodium hydroxide is placed in the bag with the plant to absorb the carbon dioxide. The plant is left for 24 hours and the leaves are tested for starch using iodine. The leaves will show that no starch has been made as no photosynthesis occurred without carbon dioxide.
An experiment to investigate photosynthesis in a de-starched plant. 2 glass jars are labelled Experiment, which contains a beaker of Sodium hydroxide, and Control, which contains a beaker of water.

Answer:
carbon dioxide is necessary for the plants because it helps in photosynthesis. It is the most basic raw material.
potassium hydroxide is used to remove carbon dioxide in the cell had experiment
