In order for plants to make their own food, they must go through a process called photosynthesis. This process occurs in the chloroplasts of a cell. To begin this process, all items needed must go to the cells of a plant. Water and nutrient are absorbed from the soil through the roots. A tube called the xylem carries only water up the stem to the rest of the plant. Gas exchange in the plants occur in the tiny pores of a leaf called the stomata. This is opened and closed by the guard cells. The food produced by this process is called ATP and it is a macromolecule known as a nucleic acid.
Answer:
This is how cells gene regulation occur.
Explanation:
Regulation of gene expression is very very important thing to maintain the normal levels of all body proteins according to our body"s requirement.
During positive gene regulation enzymes of various metabolic pathways of the target cell is being activated,thus supplying the cellular need of various metabolites and proteins.
During negative regulation various enzymes are turned off thus blocking the formation of metabolites or proteins not required by the cell.
