22. D, that means the soil uhhhh helps the roots to grow??? Also because sunlight causes photosynthesis- sorry i’m not good at this hope it helps
The answer to this question is yes
Answer:
A plant takes in carbon dioxide ( CO2 ) and water ( H2O ) and comes out with oxygen ( O2 ) and sugar/glucose ( C6H12O6 ). But Whats the science behind it all?
Explanation:
Once we humans breath out carbon dioxide, the plants open the pores in their leaves to take it in and to obtain water, the plants absorb water and nutrients through the xylem: a tissue made up of thin tubes located just below the surface of the plant's stems. The molecules in this tissue attract water molecules from the soil, so that the water is pulled upwards. This process is called capillary action. Some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. The green leaves of plants carry out both photosynthesis (in light) and respiration (all the time). Photosynthesis uses carbon dioxide to make sugar and produces oxygen as a byproduct. Respiration uses oxygen to release energy from stored sugar and produces carbon dioxide as a byproduct.
