Is carbon dioxide given off during photosynthesis and respiration?
It is given off during respiration but I don't know about photosynthesis. I think oxygen is actually given off by photosynthesis.
The plants in the bottle use oxygen for respiration. Explain why does the amount of oxygen and carbon dioxide in the bottle garden stay the same over a week?
Photosynthesis occurs in the chloroplast. During photosynthesis, carbon dioxide, water, and light energy is turned into glucose and oxygen. Cellular respiration occurs in the mitochondria. During cellular respiration, glucose and oxygen and turned into carbon dioxide, water, and energy. As you can see, the are both really a big cycle.
Plants absorb carbon dioxide by photosynthesis. They release carbon dioxide, usually at night, through respiration. Photosynthesis is a process that uses the energy of light (photo-) to fuel the conversion of carbon dioxide and water into sugars that can then be converted into plant material (-synthesis) as well as releasing oxygen. In the process of converting the sugars created by photosynthesis into other plant material, plants consume some oxygen and release carbon dioxide. This is…
During respiration (plants and animals) energy is released from sugar (glucose) by a series of chemical reactions. The sugar is broken down into carbon dioxide and water in a process which uses oxygen. Respiration is the chemical opposite of photosynthesis because it releases energy, using up food and oxygen and producing carbon dioxide. Photosynthesis requires engery (light) and produces food using up carbon dioxide and producing oxygen. Respiration is the release of energy from food…
There are 2 processes of gas exchange in plants, photosynthesis and respiration. Photosynthesis occurs during the day, plants take in carbon dioxide and expel oxygen into the environment. Respiration occurs at night and is similar to the way it occurs in animals. Plants absorb oxygen at night and expel carbon dioxide.
Cellular respiration is important to the biosphere because during the process, carbon dioxide is given off. This carbon dioxide can be used by plant cells during photosynthesis to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons
No, in general plants use carbon dioxide in photosynthesis and give off oxygen. However, during cellular respiration (at night) they do produce a small amount of CO2, but not not near enough to offset the amount of O2 produced. This is why plants are good at sequestering Carbon Dioxide. During photosynthesis: 6CO2 + 12H2O -> C6H12O6 + 6H2O + 6O2 During respiration: C6H12O6 + 6O2 + 6H2O → 12H2O + 6 CO2
Photosynthesis is the process in which carbon dioxide is converted to glucose, so carbon is stored. Respiration is the process in which carbohydrates are converted to water and carbon dioxide, so that carbon is released again into the air. During these processes, both animals and plants help themselves survive by either releasing energy or storing it. Meanwhile carbon is returned back to the air.
During photosynthesis, carbon dioxide and water are used to produce sugars and oxygen. During respiration, the sugar glucose and oxygen and used to produce carbon dioxide and water.

Only when there is insufficient sunlight to perform photosynthesis. During the day, trees and other plants absorb carbon dioxide to extract the carbon to make their food. When there is not enough light present for photosynthesis, the process is reversed and plants use cellular respiration as animals do (absorbing oxygen and releasing carbon dioxide).
