What is photosynthesis? - eschooltoday

Every living creature needs food or energy to survive. Some depend on others for food and energy, whiles others can produce their own food.

Plants make their own food, glucose, in a process called photosynthesis. We say that plants can photosynthesise.

Photosynthesis and respiration go hand in hand. The result of photosynthesis is glucose, which is stored as chemical energy in the plant cells.
This stored chemical energy comes from the conversion of inorganic carbon (carbon dioxide) into organic carbon. Respiration releases the stored chemical energy.

Photosynthesis is a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy.

Photosynthesis/Cell Respiration Flashcards | Quizlet

Carbon dioxide, is a waste product that is released during Cellular Respiration.

Light energy is absorbed by the green chemical chlorophyll. This energy allows the production of glucose by the reaction between carbon dioxide and water. Oxygen is also produced as a waste product.

Photosynthesis is a process used by plants in which energy from sunlight is used to convert carbon dioxide and water into molecules needed for growth. These molecules include sugars, enzymes and chlorophyll.

What Is The Main Waste Product Of Photosynthesis? - …

With less trees in the environment, less carbon dioxide is taken out of the air and less oxygen is produced.

This breaks the balance of cycle between Photosynthesis and Cellular Respiration and leads to problems such as global warming.

Carbon Dioxide emissions- humans rely heavily on vehicles which give off carbon dioxide.

Without this carbon balance, there would be steady climate change affecting the environment (the greenhouse effect).
Through Photosynthesis, plants emit oxygen into the environment which is needed by all living things.

There would be no plant or animal life without Photosynthesis, so life on Earth would dwindle.
How do current human endeavors threaten the balance between Photosynthesis and Cellular Respiration?
Photosynthesis is a process in which plants take in carbon dioxide from the environment.

In leaves, photosystem 1 (PS1) absorbs light and its energy is finally utilized for the conversion of carbon dioxide to biomass.

Raw Materials of Photosynthesis: Carbon Dioxide …

Photosynthesis does the opposite of respiration. Carbon dioxide is absorbed and oxygen is produced. In order to study respiration in green plants we must block out the light, because although green plants respire all the time they only photosynthesize in the light.

photosynthesis, they take in carbon dioxide and ..

Plants do breathe - they give out carbon dioxide and absorb oxygen from the air that surrounds them. Their tissues respire just as animal tissues do. Plants, however, do not have lungs or a blood stream, so we cannot say that they breathe in the same way as animals.

carbon dioxide during the process of photosynthesis.

To unlock the energy in the produced in photosynthesis, green plants need to , just as animals do. Respiration takes place in the plant's cells, using oxygen to produce energy and giving off carbon dioxide as a waste product. So in terms of the gas taken in and the gas given out, respiration is the opposite of photosynthesis.

Photosynthesis, Respiration, and Carbon Dioxide

The result is that during the day when the plant is both respiring and photosynthesising there is a two-way traffic of oxygen and carbon dioxide both into and out of the plant. During the night when the plant is respiring but not photosynthesising, oxygen is being taken in but not given out - and carbon dioxide is being given out but not taken in.

Photosynthesis, Respiration, and Carbon Dioxide

This process is extremely important for life on earth as it provides the oxygen that all other life depends on.

Just like humans and other living things, plants also need this food for many things. Let's see a few:

Glucose resulting from photosynthesis is used during respiration to release energy that the plant needs for other life processes.

The plant cells also convert some of the glucose into starch for storage. This can then be used when the plant needs them. This is why dead plants are used as biomass, because they have stored chemical energy in them)

Glucose is also needed to make other chemicals such as proteins, fats and plant sugars that are all needed for the plant to carry out essential growth and other life processes.

What is the chemical formation for carbon dioxide

Luckily, plants use up more carbon dioxide in photosynthesis than they produce in respiration, and produce more oxygen while photosynthesising than they use up while respiring - otherwise there would not be enough oxygen in the atmosphere for us animals to breathe!
