Asthma is a chronic condition, which alters the airways (bronchial tubes). The bronchial tubes function by permitting the entry and exit of air into the lungs. This syndrome is characterized by inflammation in airways, causing difficulty in breathing.

Photosynthesis includes series of chemical reactions which are carried out in chloroplast,i.e.The specialized structures found on cells of plants. In these series of reaction, water and carbon dioxide are converted into glucose and in this reaction energy from sunlight is used. Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Because plants that have chlorophyll and do photosynthesis are also plants that use carbon dioxide. Using solar energy to turn carbon dioxide and water into sugar and oxygen is what happens during photosynthesis. So if all plants do photosynthesis then the answer to your question is yes, all plants use carbon dioxide.

Sometimes a few chromosomes have non-staining secondary constrictions at a constant location. This gives the appearance of a small fragment called the satellite or trabant. These chromosomes are called sat (satellite) chromosome. Nucleolus is formed by sat chromosome.
