True or false carbon dioxide and water in the presence of sunlight will react to form sugar and oxygen gas?
False. Plants do that, but the reaction won't happen without plants.
Why is photosynthesis necessary in order for us to breathe?
Photosynthesis is necessary for us to breathe because it produces oxygen as a byproduct. During photosynthesis, plants take in carbon dioxide and water and convert them into glucose and oxygen using sunlight. The oxygen released by plants during this process is what we breathe in to survive. Without photosynthesis, oxygen levels in the atmosphere would significantly decrease and make it difficult for us to breathe.
Who discovered that plants add oxygen to air?
Jan Ingenhousz, a Dutch scientist, is credited with discovering that plants release oxygen during photosynthesis. His experiments in the 18th century demonstrated that plants produce oxygen in the presence of sunlight.
What are two reasons humans depend on plants for survival?
Because plants produce our oxygen and we can't live without oxygen, therefore we need plants to survive.
What can live with or without atmospheric oxygen?
Plants and anaerobic bacteria.
Can we get the oxygen without sunlight?
Probably not. No sunlight, no plants, and plants create oxygen . . . but we'd probably starve to death first if the sun went out.
What do plants produce in the presence of sunlight?
It will produce oxygen.
Can you produce oxygen without trees?
We can't produce oxygen without plants... That's why we need plants.. =D
Is it possible to create oxygen without plants?
Yes, oxygen can be produced through chemical reactions such as electrolysis of water or decomposition of hydrogen peroxide. These methods do not involve plants, but they require energy input to facilitate the reactions.
Can plants survive without oxygen?
No, a plant could not grow without oxygen.
How is life affected by the presence or absence of plants animals minerals and other resources?
animals need oxygen and plants produce oxygen. if there is no light for photosynthesis, then plants can not produce oxygen and animals cannot survive
What is the main purpose of plants?
To create oxygen to breathe
What produces oxygen in?
Photosynthetic leaves of the plants.
What two important things do plants provide for the living world?
The two important things that plants provide for the living world are oxygen and food. Plants are responsible for the presence of oxygen which is needed for most organisms on the planet. Plants are also a source of food, whether directly (vegetables and fruit) or indirectly (eating what ate the plants). Without plants humans would not exist.
What is a sentence for oxygen?
Plants need oxygen for photosynthesis to create energy.
What supplies oxygen?
Plants and certain types of bacteria are responsible for producing oxygen through the process of photosynthesis. Plants take in carbon dioxide and water, using sunlight to create oxygen as a byproduct. Additionally, algae in the ocean also contribute to the production of oxygen through photosynthesis.
How does the balance between CO2 and oxygen benefit the both plants and animals?
co2 helps the plants which create oxygen which helps us
